Constructing Print Queues
Once the LATprint ThinWire Ethernet Interface is installed, you need to set
up print queues that allow users to print files to the printers connected to the
LATprint interface. This chapter describes how to set up print queues using
the program on the diskette and manually, by entering commands.
See Section 2.1 for information if you are using the diskette to set up VMS
print queues. Section 2.2 contains the procedure to manually enter commands
to set up VMS print queues. Both LATSYM and DECprint Printing Services
procedures are covered in these sections.
See Section 2.4 for the procedures to set up ULTRIX print queues.

2.1 Setting Up VMS Print Queues Using the Diskette
To set up VMS print queues using the diskette you must first copy the setup
file from the diskette to a VMS directory.

2.1.1 Loading From Networked PC’s
To load from networked PC’s, copy the files to your VMS directory using
PATHWORKS or the Network File Transfer (NFT) utility. For example:
•

For PATHWORKS:
M:\ > copy b:\vms\setup.com

•

For NFT:
C:\ > nft copy b:\vms\setup.com vmsnode "username password"::

2.1.2 Loading From VMS Systems
To load from VMS systems that have a 3.5 inch disk drive, copy the files to
your VMS directory using the PCDISK utility. The following example describes
this procedure.
1. Enter PCDISK.
$ MCR PCDISK

Constructing Print Queues 2–1

2. Copy the file to your VMS drive.
pcdisk> use a: dka500:
In the example, dka500 is the VMS device specification of an RX23, or
RX23S, 3.5 inch disk drive.
3. Export the file.
A:\> export vms\setup.com
After completing the export command, the set.com file is automatically
transferred to your current directory.
4. Exit PCDISK.
A:\> exit
5. After the setup file is transferred to your directory, run the setup procedure
by entering this command:
$ @SETUP
The setup procedure collects information by prompting you to enter information
needed to construct print queues for printers connected to the LATprint ports.

2–2 Constructing Print Queues

After successfully running the setup procedure the following files are created
in your current directory.
Table 2–1 Files Created by LATprint Setup Procedure
File Name

Function

CQ.COM

Constructs LATprint queues.

DQ.COM

Deletes LATprint queues that were created by the
corresponding CQ.COM file.

MOP.COM

Establishes a LATprint management session.

You or your network manager can use the command in the MOP.COM file to
manage your LATprint interface. If you are not the system manager, deliver
the CQ.COM and DQ.COM files to your system manager.
NOTE TO SYSTEM MANAGER
To construct and start LATprint queues, incorporate commands from
CQ.COM into your system startup procedures. To stop or delete
LATprint queues created by CQ.COM, use the commands in DQ.COM
which provide a convenient means of "undoing" the actions of CQ.COM.
Commands in DQ.COM are provided for reference or utility use only.

Constructing Print Queues 2–3

2.2 Setting Up VMS Print Queues Manually
The following procedure may be used to manually set up print queues on VMS
systems for LATprint ThinWire Ethernet Interface connected printers. The
procedure takes you through the following tasks:
•

Determining prerequisite information, Section 2.2.1

•

Setting up print queues using LATSYM, Section 2.2.2

•

Setting up print queues using DECprint Printing Services, Section 2.2.3

To set up VMS queues manually, you can type in command lines. Use the
procedure outlined in Section 2.2.1 to obtain the necessary prerequisite
information, and then write the results in Table 2–3. The information from
this table is used to set up the print queues.
NOTE
You must have VMS OPER and PHY_IO privileges to execute the
commands used to set up the print queues. If you do not have these
privileges, ask your system manager to set up the print queues.

2.2.1 Determining Prerequisite Information
Use the following procedure to obtain the information necessary to set up VMS
print queues, and write the results from each step in Table 2–3.
1. Obtain the physical address that you recorded in Chapter 1.
Example: 08-00-2B-27-11-55
2. Derive the LATprint interface LAT node name from the physical address.
Example: LAT_08002B271155
Unless you or your network manager have changed the LATprint
interface LAT node name, the name is the physical address with the
prefix LAT_, without the hyphens.
3. Perform the following steps for each port you intend to configure.
a. Determine the LATprint interface port name.
Example: PORT_1
Unless you or your network manager have changed the LATprint
interface port names, the port name is PORT_1 for port 1, or
PORT_2 for port 2.

2–4 Constructing Print Queues

b. Choose a VMS LAT Port Name (LTAnnnn).
Example: LTA9999
A VMS LAT port name is needed for each LATprint port. The
required name has the form LTAnnnn, where nnnn is a unique
number. Choose a number between 1 and 9999. It is conventional
to number LAT printer ports downward from 9999, because LAT
port numbers for terminal services generally proceed upward from
1.
To show the VMS LAT port names already in use, type:
$ SHOW DEVICE LTA
c.

Create a queue name.
Example: LATPR1
The queue name may be a string of 1 to 31 characters. The
character string can include any letters, digits, the dollar sign ($),
and the underscore (_), and must include at least one alphabetic
character. To see a list of queue names already in use, type:
$ SHOW QUEUE/ALL

d. Determine the printer data type.
Use the following table as a guide to determine the printer data
type.
Example: Digital
Table 2–2 Selecting a Printer Type

For data types other than PostScript or Digital be sure to disable input flow control (Section 3.4.1).

Constructing Print Queues 2–5

Determine the queue processor.
Example: LATSYM
With printer data types other then PostScript, select LATSYM (see
Section 2.2.2).
For printers employing the PostScript data type, your choices for
queue processor include LATSYM and DECprint Printing Services
(CPS). If the printer has a DECprint license, choose DECprint
Printing Services, (see Section 2.2.3) otherwise select LATSYM to
obtain basic PostScript-only printing capability. DECprint Printing
Services offers additional printing features such as multiple data
types, user notification of printer error and status messages, and
more.

Create a description string.
Example: Dick’s printer
The description string may contain up to 255 characters.

2.2.2 Setting Up Print Queues for LATSYM
Use the following procedure to determine the commands you need to place in
system startup files to set up LATSYM print queues for LATprint interface
connected printers. Use the prerequisite information from Table 2–3 when
performing this procedure.
LAT startup information is usually located in a LAT startup file and queue
startup information in either a queue startup file or in the site-specific startup
file, typically SYS$MANAGER:SYSTARTUP_V5.COM.
Depending on your system configuration, the LAT startup file that you need to
modify is usually named LAT$SYSTARTUP.COM or LTLOAD.COM. This file is
typically located in the SYS$STARTUP: or SYS$MANAGER: directory.
Ensure that SYSTARTUP_V5.COM invokes LTLOAD.COM or LAT$STARTUP.COM,
which in turn invokes LAT$SYSTARTUP.COM. The LAT$STARTUP.COM or
LTLOAD.COM file must be executed after DECnet is running.
To assure that each print job begins with the printer in a known state, it is
necessary to instruct LATSYM to send a printer reset command between jobs.
A device control library containing reset commands for various printer data
types will be located in SYS$LIBRARY directory.

2–8 Constructing Print Queues

2.2.2.1 Modifying the LAT Startup File
This section describes the commands that you will need to place in
your LAT startup file. The name of the file is usually LTLOAD.COM or
LAT$SYSTARTUP.COM, depending on your system configuration.
1. Create the VMS LAT port.
Example: $ MCR LATCP CREATE PORT LTA9999
In the example, LTA9999 is the VMS LAT port name.
Format: $ MCR LATCP CREATE PORT vms-port-name
The CREATE PORT command of the LAT Control Program (LATCP)
creates a VMS logical port to connect with a physical port on a LAT
node.
2. Map the VMS LAT port to the LATprint node and port.
Example:
$ MCR LATCP SET PORT LTA9999 /NODE=LAT_08002B271155 /PORT=PORT_1 /QUEUED /APPLICATION
In the example, LTA9999 is the VMS LAT port name, LAT_08002B271155
is the LATprint interface LAT node name, and PORT_1 is the LATprint
interface port name.
Format:
$ MCR LATCP SET PORT vms-port-name /NODE=lat-node-name /PORT=lat-port-name /QUEUED /APPLICATION
The SET PORT command maps a VMS logical port to a physical port
on a LAT node.

Constructing Print Queues 2–9

2.2.2.2 Constructing the Reset Library
This section describes the commands you need to construct the LATprint
interface reset library. Because you need to enter the <ESC> and ^D
characters, Digital suggests you first use an editor such as EDT to create a
temporary file containing the commands and then execute the resulting file.
NOTE
In EDT, an easy way to insert ^D is to press PF1 , 4 on the main
keyboard, and then PF1 , 3 on the numeric keypad.
In EDT, an easy way to insert <ESC> is to press Ctrl +

[

twice.

1. Enter the editor. For example:
$ EDIT CONSTRUCT_RESET_LIB.COM
2. Copy the following commands into the file.
$ LIBRARY /TEXT /CREATE SYS$LIBRARY:LATPRINT
$ LIBRARY /TEXT /REPLACE SYS$LIBRARY:LATPRINT SYS$INPUT /MODULE=RESET_PS
$DECK
^D
$EOD
$ LIBRARY /TEXT /REPLACE SYS$LIBRARY:LATPRINT SYS$INPUT /MODULE=RESET_DEC
$DECK
<ESC>[!p<ESC>[<SP>s
$EOD
$ LIBRARY /TEXT /REPLACE SYS$LIBRARY:LATPRINT SYS$INPUT /MODULE=RESET_HP
$DECK
<ESC>]VMS;2<ESC>\<ESC>P<ESC>E<ESC>\
$EOD
$ LIBRARY /TEXT /REPLACE SYS$LIBRARY:LATPRINT SYS$INPUT /MODULE=RESET_IBM
$DECK
<ESC>]VMS;2<ESC>\<ESC>P<ESC>@<ESC>\
$EOD
3. Exit the editor.
4. Type @CONSTRUCT_RESET_LIB.COM to execute the commands.

2–10 Constructing Print Queues

2.2.2.3 Creating the Queue Startup Information
This section describes the commands you need to place in your queue startup
file or in your site-specific file to construct LATprint interface queues.
1. Construct a default form for LATprint interface queues.
Example:
$ DEFINE/FORM LATPRINT_DEFAULT 1 /NOTRUNCATE /WIDTH=80 /MARGIN=BOTTOM=0 /STOCK=DEFAULT /DESCRIPTION="LATprint default"
In the example, LATPRINT_DEFAULT is the name of the form, and 1 is
the number of the form.
Format:
$ DEFINE/FORM form-name, form-number /WIDTH=80 /MARGIN=BOTTOM=0 /STOCK=DEFAULT /DESCRIPTION="LATprint default"
LATprint interface queues requires a default form. In VMS each form
has a name and a number. Digital recommends the name LATPRINT_
DEFAULT for the default form of LATprint interface queues. You need
to select the number. A reasonable convention for form numbers is to
choose the lowest available form number.
To display the form numbers already in use type:
$ SHOW QUEUE/FORM
Form name
Number
-------------DEFAULT
0
CPS$DEFAULT (stock=DEFAULT) 1114

Description
----------System-defined default
CPS default

For compatibility with a wide range of printers and application
softwar,, the LATprint interface default form differs somewhat from
the typical system-defined default form. The width is 80 columns
instead of 132, there is no bottom margin instead of the usual 6 lines,
and there is no line truncation.

Constructing Print Queues 2–11

2. Set the VMS LAT port to receive no broadcast messages.
Example: $ SET TERMINAL /NOBROADCAST /PERMANENT LTA9999:
In the example, LTA9999 is the VMS LAT port name.
Format: SET TERMINAL /NOBROADCAST /PERMANENT vms-port-name
Note
The VMS operating system considers LAT ports to be terminals. The
SET TERMINAL command sets characteristics of a terminal.

3. Spool the queue to the system disk.
Example: SET DEVICE/SPOOLED LTA9999
In the example, LATPR1 is the queue name, and SYS$SYSDEVICE: is the
system disk for spooling.
Format: $ SET DEVICE/SPOOLED vms-port-name
4. Initialize and start the print queue.
Example:
$ INITIALIZE/QUEUE LATPR1 /START /PROCESSOR=LATSYM /LIBRARY=LATPRINT /FORM_MOUNTED=LATPRINT_DEFAULT /SEPARATE=RESET=RESET_DEC /ON=LTA9999
In the example,
LATPR1 is the queue name
LATPRINT_DEFAULT is the form name
RESET_DEC is the name of the reset module
LTA9999 is the VMS LAT port name
Format:
$ INIT/QUEUE queue-name/START /PROC=LATSYM /LIB=LATPRINT /FORM_MOUNTED= form-name /SEPARATE=RESET= reset-module /ON=vms-port-name
The INITIALIZE/QUEUE command creates the queue if it does not
already exist, it associates a name with the queue, and makes other
necessary associations with the queue such as the processor, a library
for setup and reset modules, a mounted form, a specific reset module,
and a port.
2–12 Constructing Print Queues

5. Set the queue description.
Example:
$ SET QUEUE LATPR1 /DESCRIPTION="LATprint Node LAT_08002B271155 port 1"
In the example, LATPR1 is the queue name, LAT_08002B271155 port 1 is
the node name and port you want to set up.
Format: SET QUEUE queue-name /DESCRIPTION=description-string
The SET QUEUE command changes the attributes of a queue. The
/DESCRIPTION qualifier specifies a string of up to 255 characters used
to provide information about the queue.
6. Set the queue default job separators and form options.
Example:
$ SET QUEUE LATPR1 /DEFAULT=(NOFEED,FORM=LATPRINT_DEFAULT)
In the example, LATPR1 is the queue name, and LATPRINT_DEFAULT is
the form name.
Format: $ SET QUEUE queue-name /DEFAULT=(option,NOFEED,FORM=form-name)
The SET QUEUE command changes the attributes of a queue. The
/DEFAULT qualifier establishes defaults for certain options of the
PRINT command. Defaults are specified by the list of options.
NOFEED instructs the queue processor to omit sending a form feed
character automatically when the printer reaches the bottom margin
of the form. The FORM option specifies the default form for jobs
submitted without a specific form request.
7. Start the queue.
8. The queue name can now be used in the print command.
Example: PRINT/QUEUE=LATPR1 TEST_FILE.TXT
In the example, LATPR1 is the queue name.
Refer to your VMS documentation, or online help for more information
about the PRINT command and its qualifiers.

Constructing Print Queues 2–13

2.2.3 Setting Up Print Queues Using DECprint Printing Services
Use the following procedure to determine the commands you need to set up
DECprint Printing Services print queues for LATprint interface connected
printers. Use the prerequisite information from Table 2–3 when performing
this procedure.
2.2.3.1 Modifying the LAT Startup File
This section describes the commands that you will need to place in
your LAT startup file. The name of the file is usually LTLOAD.COM or
LAT$SYSTARTUP.COM, depending on your system configuration. This file is
typically located in the SYS$STARTUP: or SYS$MANAGER: directory.
1. Create the VMS LAT port.
Example: $ MCR LATCP CREATE PORT LTA9998
In the example, LTA9998 is the VMS LAT port name.
Format: $ MCR LATCP CREATE PORT vms-port-name
The CREATE PORT command of the LAT Control Program (LATCP)
creates a VMS logical port to connect with a physical port on a LAT
node.
2. Map the VMS LAT port to the LATprint node and port.
Example:
$ MCR LATCP SET PORT LTA9998 /NODE=LAT_08002B271155 /PORT=PORT_2 /QUEUED /APPLICATION
In the example, LTA9998 is the VMS LAT port name, LAT_08002B271155
is the LATprint interface LAT node name, and PORT_2 is the LATprint
interface port name.
Format:
$ MCR LATCP SET PORT vms-port-name /NODE=lat-node-name /PORT=lat-port-name /QUEUED /APPLICATION
The SET PORT command maps a VMS logical port to a physical port
on a LAT node.

2–14 Constructing Print Queues

2.2.3.2 Modifying the DECprint Printing Services Startup File
Place the following command in your CPS$STARTUP.COM file and then
execute the command.
1. Place the execution queue command in your CPS$STARTUP.COM file.
Example: CPS$EXECUTION_QUEUE LATPR1 LTA9998
In the example, LATPR1 is the queue name and LTA9998 is the VMS LAT
port name.
Format: CPS$EXECUTION_QUEUE queue-name vms-port-name
2. Execute the command by typing:
$ @SYS$STARTUP:CPS$STARTUP

2.3 How to Delete a LATprint Queue
Use the following procedure when you want to delete a currently established
print queue.
1. Stop and reset the queue.
Example: $ STOP/QUEUE/RESET LATPR1
In the example, LATPR1 is the queue name.
This command abruptly stops the print queue and returns control
to the system. Any jobs that are currently executing are stopped
immediately.
2. Delete the queue.
Example: $ DELETE/QUEUE LATPR1
In the example, LATPR1 is the queue name.
The DELETE/QUEUE command takes effect only if the specified queue
(LATPR1) has been stopped first (Step 1.). Any pending jobs in the
queue will be deleted when the queue is deleted.

Constructing Print Queues 2–15

3. Unspool the device.
Example: $ SET DEVICE LTA9999 /NOSPOOL
In the example, LTA9999 is the VMS LAT port name.
This command controls whether files are spooled to an intermediate
disk. The /NOSPOOL qualifier stops the files from being spooled to the
disk.
4. Delete the VMS LAT port name assigned to the applications port.
Example: $ MCR LATCP DELETE PORT LTA9999
In the example, LTA9999 is the VMS LAT port name.
This command deletes a logical port from a VMS node.
5. Delete the LATPRINT_DEFAULT form.
Example: $ DELETE/FORM LATPRINT_DEFAULT
In the example, LATPRINT_DEFAULT is the name of the form.
This command deletes a form for the printer queue previously
established with the DEFINE/FORM command.
The print queue is now removed. See Section 2.2 for the procedure to
establish a new print queue.

2.4 LATprint Queue Setup Procedure for ULTRIX
The following procedure may be used to manually set up print queues on
ULTRIX systems for LATprint interface connected printers. The procedure
takes you through the following tasks:
•

Defining LAT terminal lines

•

Creating device special files using the MAKEDEV command

•

Updating the terminal initialization file (/etc/ttys), printer capability
database (/etc/printcap), using the lprsetup command
NOTE
You must be logged in as a superuser in order to configure print
queues. If you do not have these privileges, see your system manager
to set up the print queues.

The lta terminal driver provides support for remote terminals (which includes
printer terminal lines) using Local Area Transport (LAT) protocol. The LAT
protocol allows you to access printers connected to either port on the LATprint
interface. LAT lines are created in sets of 16, and the ULTRIX software
provides a default of 16 LAT lines, which corresponds to lta0. The LATprint
interface will use up to two of those lines; one for each port.

Constructing Print Queues 2–17

2.4.1 Verifying That LAT is in Your System Configuration
Use the following procedure to verify that LAT is in your system configuration.
1. Type the following command:
# egrep ’LAT|lat|lta’
/usr/sys/conf/vax/[hostname]
# egrep ’LAT|lat|lta’
/usr/sys/conf/mips/[hostname]
In the example, the pathname of the system configuration file is /usr/sys
/conf/vax, or /usr/sys/conf/mips, depending on whether you are configuring a
VAX or MIPS machine, and the system configuration file name is the host
name of the machine in uppercase.
•

You should observe the following output:
options
pseudo-device
pseudo-device

LAT
lat
lta

If the above command does not yield the output as shown, you must add
LAT devices to your system configuration by including the following lines
in the system configuration file, if they are not already there:
options
.
.
.
pseudo-device
pseudo-device

LAT

lat
lta

After changing the system configuration file, use the ‘‘doconfig’’ command to
reconfigure your system. For more information on adding LAT devices to your
system see the Guide to System and Network Setup.

2.4.2 Making Special Files for the LAT Ports
Use the following procedure to make the special files for lta0.
1. Enter this command:
# cd /dev ; MAKEDEV lta0
If the special files already exist, the MAKEDEV command will have no
effect. If the special files do not exist, MAKEDEV will create them.

2–18 Constructing Print Queues

2.4.3 Setting Up LAT Ports for Use With Printers
Use the following procedure to select the LAT Terminal Line(s) to use with
your printer(s), for example /dev/tty15.
1. Modify the LAT printer terminal lines listed in the /etc/ttys file that
correspond to the terminal lines you are using for your printer. For
example, you may already have an entry similar to the following:
tty15 "/etc/getty std.9600" vt100

on nomodem # LAT

If you have a similar entry (or no entry at all), modify it (or insert one) to
read as follows:
tty15 "/etc/getty 8bit.9600" vt100

off nomodem # LAT printer

Modify one or two LAT terminal entrys, depending on the number of
printers you have connected to the LATprint ThinWire Ethernet Interface.
2. Using the following example as a guide, place an lcp entry in the /etc
/rc.local file. Be sure the new entry appears after the "local daemons"
section:
if [ -f /etc/lcp ]; then
/etc/lcp -s -h /dev/tty14:LAT_08002Bxxyyzz:PORT_1 >/dev/console
fi
if [ -f /etc/lcp ]; then
/etc/lcp -s -h /dev/tty15:LAT_08002Bxxyyzz:PORT_2 >/dev/console
fi
In the example, tty14 and tty15 are the selected terminal, LAT_
08002Bxxyyzz is the LAT node name, and PORT_1 and PORT_2 are
the LAT port names.
3. To immediately effect the changes, you can enter the following command or
reboot the system:
# /etc/lcp -s -h /dev/tty14 ; /etc/lcp -s -h /dev/tty15 ; kill -HUP 1

2.5 Adding Printers With lprsetup
If you are not using PATHWORKS for ULTRIX, you can use the lprsetup
command to add printers to your system. The lprsetup command allows you
to add printers to your system. With information you provide, the lprsetup
command does the following:
•

Creates an /etc/printcap entry

•

Creates a spooling directory

•

Creates accounting files

•

Creates error log files
NOTE
The lprsetup command is a component of the optional software
subset ULTPRINTxxx (for VAX machines) or UDTPRINTxxx (for MIPS
machines). If you have not added the optional subset, you must do
so before using the lprsetup command. See the Guide to System
Environment Setup and the setld(8) reference page for information on
adding software subsets.

2.5.1 lprsetup Command
Before running the lprsetup command, you should determine the type of
printer you are adding. The lprsetup command provides default settings
based on the type of printer you specify.
The lprsetup command allows you great flexibility in setting up parameters
for your printer. For an explanation of the printer parameters, see the Guide
to System and Environment Setup, and the "printcap(5)" reference page. For
sample /etc/printcap entries, see the /etc/printcap.examples file.
NOTE
At any point during the following procedure, you can terminate
lprsetup with no modifications to the system files by pressing CTRL/C.

1. Type the following command:
# lprsetup

2.5.3 Controlling ULTRIX Print Jobs
The programs that control the ULTRIX print jobs are shown below. Examples
are shown specifically for the LATprint laser1 printer configured in the
previous example using the lprsetup command:
Table 2–9 ULTRIX Programs that Control Print Jobs
Program

Description

/usr/lib/lpd

This program, the line printer daemon, is a print spool handler.
Normally, the program is invoked at boot time from the "rc"
file. The daemon works with several system programs and files
to coordinate and synchronize printer activity. The ULTRIX
operating system supplies this file. Although you cannot modify
the file, you can specify spooling, logging, and locking activities.
You must have superuser privileges to access this program.

/etc/lpc

This program lets you control the operation of the line printer
system. While most control functions are available only to the
superuser, some functions can be accessed by general users.

/usr/ucb/lpr

This program lets you queue files for printing. For example:

% lpr -Plaser1 memo.txt
or

% cat memo.txt | lpr -Plaser1
/usr/ucb/lpq

This program lets you examine the status of jobs currently on a
print queue. For example:

% lpq -Plaser1
If there is a job in the queue, you will observe output similar to
the following:

laser1 is ready and printing via dev
Rank Owner Job Files Total Size
active root 25 memo.txt 3410 bytes
/usr/ucb/lprm

This program lets you remove jobs from the print queue. For
example:

% lprm -Plaser1 25
In the example, 25 is the job number located using the ‘‘lpq’’
command.
/etc/pac

2–26 Constructing Print Queues

This program generates accounting information about printer
use at your site. You must have superuser privileges to use this
program.

Managing LATprint
You can manage your LATprint ThinWire Ethernet Interface either locally or
from a remote device on the network. To manage LATprint interface locally,
a terminal is connected to one of the ports on the LATprint interface. To
manage it from a remote device, use the Maintenance Operations Protocol
(MOP) console carrier. MOP is a maintenance protocol specified in the Digital
Network Architecture (DNA) that is used to implement the remote console
facility and to perform remote management and loopback tests.
Managing the LATprint interface includes:
•

Examining port and server parameters and network counters

•

Setting port parameters

•

Setting server name, prompt, and zeroing counters

•

Security
Setting and clearing authorized mode
Enabling and disabling manager mode
Changing the password

3.1 Remote Management
You can manage the LATprint ThinWire Ethernet Interface from a remote
node on the network using NCP from VMS, or the console carrier from
ULTRIX. Once the management session is established, use the SET and
SHOW commands to examine and set the various port and server parameters.
Use the RESET command to reset ports and the server to the power-up state.

Managing LATprint 3–1

3.1.1 Managing LATprint from VMS
The Maintenance Operation Protocol (MOP) facility, used to establish remote
management sessions is included as part of the Network Control Program
(NCP) facility on VMS operating systems. You need a DECnet license to
operate NCP.
You do not need increased user privileges to use NCP to establish a
management session. To establish a management session, you must know
the following:
•

Ethernet address of the LATprint interface to be managed (recorded in
Chapter 1)

•

Ethernet name of the circuit that contains the LATprint interface

The Ethernet address is on the label of the LATprint interface side panel. You
need the circuit name because a VMS operating system may have more than
one Ethernet interface. To find out the circuit line name on your system type
the following commands:
$ MCR NCP
$ NCP> SHOW KNOWN LINES
Known Line Volatile Summary as of 14-JUL-1992 15:21:28
Line

State

BNA-0

BNA-0 is the line name.

3–2 Managing LATprint

NOTE
MOP will not work across network bridges because the LAT protocol
cannot be passed. Both the LATprint interface and the host must be on
the same Ethernet segment.

The following example demonstrates the VMS command that is used to
establish a management session from a VAXstation 3100 system to a LATprint
interface. The Ethernet address of the LATprint interface in this example is
08-00-2B-08-32-2B, and SVA-0 identifies the system’s Ethernet circuit name.
$ MCR NCP
$ NCP> CONNECT VIA SVA-0 PHY ADDR 08-00-2B-08-32-2B
Console connected (press CTRL/D when finished)
->
3.1.1.1 Accessing a LATprint interface Repeatedly
If you need to access a specific LATprint interface repeatedly, you can enter the
Ethernet address for it in the NCP database. This is usually done by choosing
an arbitrary address in area 13. DECserver names in the NCP database can
have a maximum of six characters. The user must have VMS OPER and PHY_
IO privileges to modify the NCP database.
For example, if you define your LATprint interface as LATPR on address 13.1
and then access it from a VAX 6400 (Ethernet circuit name BNA-0), you would
use the following commands:
$ NCP> DEFINE NODE LATPR ADDRESS 13.1 HARDWARE ADDRESS 08-00-2B-08-32-2B SERVICE CIR BNA-0
NCP> SET NODE LATPR ALL
To access the LATprint interface, type the following:
$ NCP CONNECT NODE LATPR

Managing LATprint 3–3

3.1.2 Managing LATprint From ULTRIX
On ULTRIX operating systems, the console carrier (that allows you to establish
a remote management session) is a separate utility included as part of the
MOP option. The option is part of the regular distribution but is not selected
by default and is not included in the basic installation. You can install MOP
from the original distribution media by using the setld utility. You must have
superuser privileges to invoke console carrier.
NOTE
After the console connect, ccr for ULTRIX freezes the process. You
must have DECnet Phase 5 patched ccr executable to operate properly.

After the MOP option is installed, give the LATprint interface a name and a
dummy node number, using the addnode utility. For example:
# addnode 13.1 LATPR
After the name and node number are assigned, you can establish the link at
any time by using the ccr command. For example:
# ccr -n LATPR -h 08-00-2B-08-32-2B -c sva-0
In this example, the -h qualifier is followed by the station address of the
LATprint interface unit to be attached. The -c qualifier is followed by the
name of the Ethernet circuit to use for the connection. Table 3–2 is a partial
list of Ethernet circuit names, based on system type.

3–4 Managing LATprint

3.1.3 Local Management
Perform local management of the LATprint interface by connecting a terminal
to one of its ports and using the SET, SHOW, and RESET commands. Refer to
Appendix B for additional information about using the LATprint interface as a
terminal server.

3.2 LATprint Security
Security for the LATprint ThinWire Ethernet Interface is provided by a
password-protected management mode. This mode of operation is called
authorized mode and can be set and cleared as required. When authorized
mode is set, the following conditions exist:
•

Terminal users can only set the parameters of their own port and show the
server’s parameters.

•

Manager mode must be enabled (password required) to set server
parameters or port parameters on a port other than the one to which
you are connected.

•

Manager mode must be enabled to change the password.

When the LATprint interface is first installed, authorized mode is not set, and
you can use either port to set the other port’s parameters and the server’s
parameters. Setting authorized mode requires physically accessing the unit,
entering a password, and verifying the password.
NOTE
The unit’s power must be cycled (turned off and then on) within one
minute of entering the password for authorized mode to be set. Cycling
power verifies that you have access to the unit and causes the password
to be saved in the unit’s Non-Volatile Random Acess Memory (NVRAM).
The self-test indicator flashes during the minute you have to power
cycle the LATprint interface when changing to authorized mode.

Managing LATprint 3–5

3.3 Management Commands
To manage the LATprint ThinWire Ethernet Interface you use the SET, SHOW,
and RESET commands. Use the SET and SHOW commands from the menu
to show or set parameters. A command line mode is available for use by
network management software, or by users that want to bypass the menu
interface. Refer to the Section 3.7 at the end of this chapter, for more detailed
information about using command lines to communicate with the LATprint
interface.
The following sections show how to use the SET, SHOW, and RESET
commands using the menu or the command line.

3.4 SET Command
The SET command allows you to set port or server parameters, zero network
counters, and enable and use the LATprint ThinWire Ethernet Interface
security features.

3.4.1 Setting Port Parameters
Port parameters can be set from the menu or by a command line entered at the
prompt.
The following port parameters can be set for each port:
•

Port name

3.7 The Command Line
The LATprint ThinWire Ethernet Interface user interface provides a command
line interpreter as an alternate means to SET, SHOW, or RESET port and
server parameters. The command line interpreter helps with the control of the
LATprint interface by network management software and by users who want
to bypass the menu interface.
For command line entries, the commands and parameters are not entered
through a menu. Rather, your input is echoed and the complete command is
processed after a Return is entered. Note that any error in parsing a command
will cause the entire command to be ignored.
A space is required between the command (SET, SHOW, or RESET) and its
parameters. The command line interpreter uses a comma (,) as a delimiter to
separate the different fields in a command line. To make the command line
interpreter easier to use, the current value (default) for a field will be used
when:
•

There is no entry for a field.

•

A Return is pressed before all the parameters are entered.

Table 3–5 lists the command lines that can be entered at the LATprint
interface prompt (->) to SET, SHOW, or RESET parameters.

Using LATprint As a Terminal Server
Although the LATprint ThinWire Ethernet Interface is designed primarily as
a printer server, it can also be used as a terminal server when a terminal is
connected to one of its ports. This chapter describes how to start a terminal
session and covers basic terminal server operation. For additional information
about using the LATprint interface as a terminal server, refer to the DECserver
90L+ Owner’s Manual (see Appendix C for ordering information).

B.1 Using a Terminal or Personal Computer
This section explains how to use the LATprint ThinWire Ethernet Interface
with a terminal or personal computer (PC) running terminal emulation
software.

B.1.1 Establishing a Terminal Session
1. Define a terminal port using MOP.
a. Use another system terminal and NCP to establish a MOP session to
the LATprint interface (see Section 3.1.1 or Section 3.1.2).
b. Change one of the LATprint interface ports to the following settings
(see Section 3.4).
•

Type

= TERM

•

Break

= LOCAL

•

AutoConf = ENA

2. Establish a terminal session.
a. Connect a terminal or a PC with a terminal emulation software to the
LATprint interface port.

Using LATprint As a Terminal Server B–1

NOTE
To connect a PC communication port to the LATprint interface, use
the DECconnect adapter, H8571-J and a BC16E cable. To connect a
terminal with a 25-pin D-sub mail connector to the LATprint interface,
use the DECconnect adapter, H8575-A and a BC16E cable.

b. Press the Return key twice to see the LATprint interface prompt: ->.
c.

At the prompt (->), type your service name and press Return . The
LATprint interface indicates that it is attempting to connect by
displaying a string of dots "...." on the screen.

The following example shows the connection to a service named RED.
-> RED

Return

................
%LATPR-108, RED session 1 established
Welcome to MYNODE running VMS 5.4
Username:
Note
The LATprint interface does not require the configuration of group
codes. The first time it connects to a service, it learns the service name.
This can take up to 60 seconds.

The terminal session is established and control is passed to the specified
host. If you do not know the services offered by your host(s), ask your system
manager.
When a terminal session is established, most systems start some type of log
in sequence, such as prompting you for username and password. Refer to the
documentation for your specific system for information about starting a session.

B–2 Using LATprint As a Terminal Server

B.1.2 Verify Ports
You can verify the operation of the port by typing a character on the terminal
while watching the Activity indicator on the LATprint interface. The indicator
should blink on and off, indicating activity on the port.
Refer to Table B–1 for supported terminal characteristics.

B.1.3 Verify Network
You can verify the operation of the network by entering SHOW S at the
prompt (->) and then pressing Return . The server characteristics screen will
verify if the network is "OK" or "Failed". If Failed, make sure the server is on
a properly configured network.

B.1.4 Ending a Terminal Session
A terminal session is ended by logging off or disconnecting from the system
where your terminal session was running. Logging off a system ends your
terminal session and returns you to the LATprint interface prompt. The
following example shows what happens when a user logs off the service RED.
$ LO

B.1.5 Last Number Redial
Last number redial allows a port to connect to the last service accessed without
entering the service or node name. This is done by entering the CONNECT
command C[ONNECT] at the LATprint interface prompt and pressing Return .
The following example shows how to use the last number redial feature to
reconnect to service RED.
$ LO

B.1.6 Interrupting a Terminal Session
You can interrupt a terminal session and return to the LATprint interface
prompt by pressing the Break key on the terminal. When you press the Break
key, the session is interrupted, not ended, and the LATprint interface prompt
appears (->).
At this point you can issue a SHOW or SET command, resume the interrupted
session, cycle forward or backward to other sessions, or end the session. The
following is an example of displaying the sessions active for Port 1. The
asterisk next to the service name of session 1 shows it as the default session to
which you are returned.

B.1.7 Resuming an Interrupted Terminal Session
To resume the current interrupted terminal session, type the connect command
> or RESU[ME] at the LATprint interface prompt. To resume a specific
session, type the command and specify the session number. In the case of
a MOP session, type M in place of the session number. The following is an
example of resuming terminal session 2 for a port.
-> > 2

Return

-> %LATPR-112, YELLOW session 2 resumed
When you resume an interrupted session, control is returned to the point at
which the session was interrupted.

B.1.8 Cycle Forward from an Interrupted Terminal Session
After you interrupt a terminal session, you can cycle forward to the next
session. This is done by entering the FORWARD (F) command at the LATprint
interface prompt and pressing Return . The following is an example of having
interrupted session 2 and forwarding to session 3.
-> F

Return

-> %LATPR-112, GREEN session 3 resumed

B–6 Using LATprint As a Terminal Server

B.1.9 Cycle Backward from an Interrupted Terminal Session
After you interrupt a terminal session, you can cycle backward to the
session before the session that was interrupted. This is done by entering
the BACKWARD command B[ACKWARD] at the LATprint interface prompt
and pressing Return . The following is an example of having interrupted session
2 and cycling backward to session 1.
-> B

Return

-> %LATPR-112, RED session 1 resumed
Note
There are no definable switch characters to immediately go forward
and backward between sessions as in other Digital terminal servers.
The FORWARD and BACKWARD commands are circular, that is, they
"loop" or "cycle" through the number of established sessions.

B.1.10 Disconnecting an Interrupted Terminal Session
After you interrupt a terminal session, you might change your mind and decide
not to resume the session. In this case, you can disconnect the session by
typing the disconnect symbol < or D[ISCONNECT] at the LATprint interface
prompt.
To disconnect a specific session, type the command and specify the session
number. In the case of a MOP session, type M in place of the session number.
The following is an example of disconnecting terminal session 4 for a port.
-> < 4

Return

-> %LATPR-112, BLUE session 4 disconnected
When you disconnect an interrupted session, your session is stopped and the
LATprint interface prompt appears on your terminal.
Note
Entering the DISCONNECT command when there is no interrupted
session to resume causes the port to enter its power-up state
(non-autobaud state).

Using LATprint As a Terminal Server B–7

B.2 Using MOP Console Carrier
Maintenance Operations Protocol (MOP) is a maintenance protocol specified in
the Digital Network Architecture (DNA) that is used to implement the remote
console facility and to perform remote management and loopback tests.
The LATprint ThinWire Ethernet Interface supports the remote console
facility also known as console carrier. Within console carrier there are two
components: console requester, and console server.

B.2.1 Operating as a Console Requester
The LATprint interface can operate as a console requester. As a console
requester, the LATprint interface establishes a MOP console carrier session
with another console server on the same network. This is done by using the
M[OP] command and the network device’s Ethernet address. The LATprint
interface also supports a verification code if required by the console server.
The following is an example of establishing a connection from a LATprint
interface to another LATprint interface. The Ethernet address of the device is
08-00-2B-19-8B-AF.
MYSERVER> MOP 08-00-2B-19-8B-AF

Return

-> %LATPR-113, Console connected (press Ctrl/D when finished)
-> (prompt from connected device)
Note
The RESUME and DISCONNECT commands can be used for a MOP
session by typing RESU[ME] M or D[ISCONNECT] M.
If a MOP session is active, use of the F[ORWARD] and B[ACKWARD]
commands will cycle through the MOP session.

B–8 Using LATprint As a Terminal Server

B.2.2 Operating as a Console Server
The LATprint interface can also operate as a console server. A console server
allows another requester to connect to its console port. This function is used
for remote management of the LATprint interface. The following shows
how a VMS system can establish a console carrier session with a LATprint
interface. The Ethernet address of the LATprint interface in this example is
08-00-2B-08-32-2B and SVA-0 identifies the VMS system’s Ethernet circuit
name.
$ MCR NCP
$ NCP> CONNECT VIA SVA-0 PHY ADDR 08-00-2B-08-32-2B
