How to Use This Manual

Introduction
With VAX Public Access Communications (VAXPAC), you can use your computer
system to communicate with other computer systems. The system with which
you communicate is called the remote system. Your system uses one or more
modems to communicate with a remote system over phone lines.
You can, for example, use VAXPAC to get timely business information from such
remote sources as The Dow Jones News/Retrieval Service, The SOURCE, or
CompuServe. Or, you may want to communicate with one of your own remote
branch offices. In this case, you can use VAXPAC to do work on the remote
system from the system in your office, or to transfer files back and forth. You
can communicate with any remote system to which you have access that has the
industry-standard asynchronous RS-232C, RS-422, or RS-423 interfaces.
VAXPAC is not, however, a communications network. If there are several computers at one site, DIGITAL recommends you use DECnet.
Intended Audience
This manual is intended for system managers and those responsible for setting
up and maintaining systems that communicate with remote databases. Some
knowledge of VMS or A-to-Z systems is helpful.

1.1

VAXPAC Installation Requirements

It takes approximately 10 to 20 minutes to install the VAXPAC software. The
time varies depending on the distribution medium and the system on which you
are installing VAXPAC.
To install VAXPAC, you need the following:
e

Any VAX CPU.
VAXPAC

can also be installed on a VAXcluster.

Distribution media: either one TK50 tape cartridge, three RX50 diskettes, or
one 9-track 1600 bpi magnetic tape.

A modem connected to a phone line.

Modem cables.

The VAXPAC installation kit, which includes the distribution media, the
documentation, and the VIT200/VT300 keystrip.

1.1.1

Disk Space

VAXPAC requires the following space on the system disk: 2400 blocks of disk
space for installation and 1000 blocks for use.
1.1.2

System Disk Backup

Before you begin installing VAXPAC V1.1, you need to back up (make a copy of)
your system disk. Backing up the system disk is a standard precaution before
installing any VMS layered product. If you are unsure of how to back up a system
disk, see your VMS system management documentation.

1-2

Installation Procedures

1.1.3

Installing on VAXclusters

If you have previously installed VAXPAC in a VAXcluster environment, you
should perform the following steps prior to installing VAXPAC V1.1 if you want to
preserve any definitions on each member of the cluster.
1.

Log into the system manager’s account for each system in the VAXcluster and
determine whether the file SYS$SYSTEM:COMM$SYSTEM.DAT exists.

When you find the file COMM$SYSTEM.DAT,

rename the file:

S$ RENAME/LOG SYSSSPECIFIC: [SYSEXE [COMMSSYSTEM. DAT
_To:
SYSSCOMMON: [SYSEXE] COMMSSYSTEM.DAT_‘ f$getsyi ("nodename")

In the above command, ‘f$getsyi("nodename") will be evaluated to the actual
node name for the system you are currently logged into.
3.

You can examine the data in this file later by using the logical name

COMM$SYSTEM to point to a system file for a particular node. For example:
$

DEFINE

COMMSSYSTEM

SYSSCOMMON:
[SYSEXE] COMMS$SYSTEM.DAT_MYNODE

Ifyou intend to use the system file provided with VAXPAC V1.1, you should
make a note of any data you have entered into the system file. Use the

VAXPAC

Manager’s Menu

options SET, GRP, STD,

SYS, SEC, MOD,

SRV, and KEY to determine which records you want to preserve.

XFR,

You can preserve your existing data for one node by copying the file to the
shared area. For example:
$ COPY SYSSSYSTEM:COMMSSYSTEM.DAT_MYNODE
_To:
SYSSCOMMON: [SYSEXE] COMMSSYSTEM.DAT

If you follow this procedure, all of the data you have entered will be preserved.

1.2

VMS and MicroVMS Installation Procedure

There are two varieties of the VMS operating system: regular VMS and
MicroVMS. Use the VMS and MicroVMS installation procedure to install
VAXPAC. This is the same procedure used to install all applications for VMS
and MicroVMS.
The VAXPAC installation kit comes on 9-track magnetic tape, RX50 diskettes, or
TK50 tape cartridge.

Installation Procedures

1-3

Before proceeding, be certain that you have made a copy of your system disk on
either diskette, tape, or hard disk.
Follow these steps to install VAXPAC:
1.

If you are installing VAXPAC with diskettes you must determine which device
number (for example, DUA1 or DUA2) to use during installation.
If you are not installing VAXPAC with diskettes, skip this step and proceed to
step 3.
:
To determine the device number, enter the following command:
$ SHOW DEVICE/FULL DU

This shows the device type and device number. For example, you may have
a device number of DUA1 and a device type of RX50. (A device type of RX50
indicates a diskette.) Make a note of the device number and type. The Guide
to VAX/VMS Software Installation explains this procedure in greater detail
in the section "Naming Devices."
Begin the installation by invoking the VMSINSTAL procedure, specifying
VAXPAC as the product you are installing, indicating the device on which
your distribution medium is mounted (determined in step 2), and specifying
OPTIONS N to print or display the release notes. For example:
$ @SYSSUPDATE:VMSINSTAL VAXPAC MUAO:

OPTIONS N

If you have DECnet installed, the following warning message might appear.
You will also be warned if other users are logged in.

1.4

Post-Installation Requirements

This section lists the system parameters and the privileges you need to use and
manage VAXPAC.
1.4.1

System Parameters

The SYSGEN parameter TTY_ALTYPAHD must have a value of 512 or greater.
If the value is less than 512, there may be data overrun errors; that is, characters

from the remote system may be lost, especially if you use high-speed lines.

The following procedure describes how to check this parameter and, if necessary,
change it:
1.

To check the value of TTY_ALTYPAHD,
Command Language (DCL) prompt:

enter the following at the DIGITAL

S$ RUN SYSSSYSTEM: SYSGEN
SYSGEN> USE CURRENT
SYSGEN> SHOW TTY_ALTYPAHD
SYSGEN> EXIT

If the value assigned to TTY_ALTYPAHD is less than 512, you must modify
the system parameter file SYS$SYSTEM:MODPARAMS.DAT and add the
following line at the end of the file:
TTY _ALTYPAHD

512

(You may set a higher value if you want.)
You must then run AUTOGEN to re—compute your system parameters:
$

@SYSSUPDATE:AUTOGEN

SAVPARAMS

REBOOT

Installation Procedures

1—9

AUTOGEN performs an automatic shutdown, and reboots when it has finished. (For more information on AUTOGEN, see the Guide to VAX/VMS
Management and Daily Operation.)
Note that if you are using VAXPAC on a VAXcluster, you need to make this
change on each node in the cluster.
1.4.2

Privileges

Users of VAX Public Access Communications V1.1 need the TMPMBX (may create
temporary mailbox) privilege.
|
In order to use the system manager’s features of VAXPAC, you need the following
privileges:
|
TMPMBX

May create temporary mailbox

SYSPRV

May access objects via system protection

OPER

Operator privilege

PHY_IO

May do physical I/O

If the spawn feature of VMS has been disabled on your system, you should install
COMM$SYSTEM:COMM$DTE.EXE with SYSPRV. If you do not do this, you
cannot use VAXPAC file transfer features.
1.5

Modems

Modems usually require setup before they can be used with VAXPAC.
When you buy a new moden, it is often set up at the factory for operation with
a terminal or personal computer. The requirements for operating the modem
with a multi-user computer system, such as one supporting VAXPAC, are usually
different, particularly with reference to dial—in to the system and breaking the
phone connection.
Note
The modem must hang up the phone line when the signal Data
Terminal Ready (DTR) is dropped. If you use VAXPAC with a modem that does not do this, VAXPAC will be unable to hang up the
phone, which can cause you to incur excessive phone charges.

1-10

installation Procedures

The setup method varies with the type of modem. Some modems require switches
to be set within the modem. Others require you to enter commands from the
terminal. In the latter case, some modems require the commands to be entered
every time power is turned on, while others allow the settings to be stored
permanently. Your modem documentation describes the procedures for changing
the setup of your modem.
See Appendixes C and D for additional technical details on modem setup and
commands.
You can use most types of modems

to communicate

VAXPAC supports the following modems:

with a remote

Digital Scholar 2400 (DF224)

Digital Scholar Plus (DF242)

Digital DF112

Digital DFAO1

Digital DFO3 and DF03 compatible modems

Hayes Smart Modem 2400 and Hayes Smart Modem 1200

system.

(See Appendix E for information on using a DTE_DF03, DTE_DF112, or DMCL
dial module with a DMF32

controller.)

If you have a different type of modem, you must use the MOD - Define modems
option (see Section 2.5.3) to enter the information for that modem.
Note

For VAX Public Access Communications to work, you must use the
correct modem connecting cable. A cable not certified for use with your
modem can lead to faulty connections.

Installation Procedures

1—11

1.6

Installing Modems

It is important that you identify the proper port before attaching the modem to
the back of your system.
You are already familiar with ports because you used at least two ports to attach
your terminal and printer to your system. You can use any of the remaining ports
to connect modems.
Each port has a device name. When you use the Manager’s Main menu option
SET to set up communication lines, you must be able to identify the device name
assigned to the port to which you attach the modem. The following section helps
you determine which device names are assigned to the ports, and how you can
identify them.
Enter the following DCL command to determine the device name for the ports on

your system:
S$

SHOW

DEVICE

The system displays a listing of device names.
follows:
TXAO
TTAO

thru
thru

TXA7
TTA3

lines)

To find out which device name is associated with a particular port on your system,
follow these steps:
1.

Disconnect your terminal cable connection from its port on the system.

Temporarily attach your terminal cable connection to the port on the system
where you will be attaching the modem.

Enter the following DCL command:
$

SHOW

TERMINAL

The system displays a screen showing your terminal characteristics, including
Physical Terminal or Terminal followed by a device name. This is the
device name of the port to which your terminal is now attached. For example,
if your terminal is attached to TXA3, this is the device name that appears
next to Physical Terminal or Terminal. Make note of this device name
because you must enter this device name when you use the SET option on
the Manager’s Main menu to set up communication lines.

1—12

Installation Procedures

Log out.

Switch your terminal cable connection back to its original port on your
terminal.

Attach the modem cable to the port on the system you identified when
checking for device name. Use a DEC BC22E, DEC BCC04, or equivalent
cable to connect the modem to the system. Refer to the documentation for
your modem for complete information on connecting the modem.

Log back in.

If you are using VAXPAC in a VAXcluster, you must log in to each system within
the cluster that will have a modem attached to it.

1.7

Testing Modem Connections

Test all connections before attempting to use VAXPAC. It is essential that you be
able to communicate between your system and the remote system through the
modem.
In most cases, the modem is connected to your system with a special cable. This
cable must be connected to the proper port on your system. Check that the cable
connecting your modem and system is the proper one. DIGITAL recommends
that you use a DEC BC22E or DEC BCC04 cable. Your modem installation guide
might list alternatives.
Figure 1-1 shows a typical standalone modem and its connections, including the
power outlet, telephone handset, wall outlet connections, and terminal.

These connections might differ depending on the type of modem you are using.
Refer to your modem installation guide for more detailed instructions.
To test modem connections, you need a phone number you can dial. The phone
number for the Digital Electronic Store is readily available and can be used for
this test. Dial 800-DEC-DEMO (800-832-3366).
There are two ways to test modem connections:

(1) Connect the modem to the

communication port on your terminal and test connections at your terminal, or

(2) use VAXPAC. The following sections explain how to test connections using
each method. Note that testing connections with VAXPAC is usually easier, but it
does require some knowledge of VAXPAC.

Your response to this field depends on the type of telephone service
you have (pulse or tone). Push-button phones use tone dialing and
are more common in business environments. Rotary dial phones
use pulse dialing. DIGITAL modems are equipped to handle both
pulse and tone dialing. If you are not sure which type of telephone
service you have, contact your local telephone company.

Transmit speed:

Specify the speed at which the modem can receive characters
from the local system. This speed is specified in the modem
documentation.

Receive speed:

Specify Yes if you need to disable the communication line due to a
problem with the phone line or modem. When you disable a line, it
is available only to the system manager. A disabled line is ignored
in all groups of communication lines that reference it.

Note
The transmit and receive speeds you specify are used when dialing
the remote system. Depending on the modem type, these speeds can
be superseded by the speeds you specify for the connection when
the remote system has answered. In other words, the transmit and
receive speeds are current only until the remote-system answers.

GRP - Group Communication

Lines

The GRP option lets you combine up to 12 communication lines into one group.
This allows VAXPAC to reach a remote system using any communication line in
the group. For example, if one communication line in the group is being used
by someone else, VAXPAC uses the next available line in the group to reach the

remote system.

If you have more than one modem or several direct connections to the same
system, use this feature.
You can add, change, delete, or display communication lines. If there are no
communication lines defined when you select GRP from the Main menu, a screen
for adding a new communication line appears. Thereafter, when you select the
GRP option, a list of the communication lines you have already set up appears.

the modem appears in the list of available modems.

Dial module:

A dial module is a type of software that can communicate with a
modem. VAXPAC has two built-in dial modules. They are:
*GENERIC - The most flexible of the dial modules. A connection

is treated as successful when carrier is detected. An unsuccessful
connection occurs when either
is pressed before carrier is
detected, or carrier is not detected within the time allowed for the

connection. Select the *+GENERIC dial module if you are using a
DMF32 controller (see Appendix E).

Managing VAX Public Access Communications

2-25

*DMCL - This dial module supports Digital’s Modem Command
Language (DMCL) and is specific to the new family of modems
being developed by Digital Equipment Corporation. Because it
is specialized, it can take advantage of the special features of
DIGITAL modems supporting DMCL, such as automatic speed
matching. The DFAO1 and the Digital Scholar Plus (DF242)
modems support DMCL.
In addition

to the dial modules

listed here, VAXPAC

can use

the dial modules supplied with VMS for the DCL command SET
HOST/DTE (for example, DTE_DF03 for the DF03 modem). The
source program file SYS$SEXAMPLES:DTE_DF03.MAR is provided
with VMS as an example of such a dial module.

The ability to support computer dialing is commonly known as
autodial. Most modems allow autodialing from either a terminal
or a computer. Some older modems do not allow this feature and
require the use of a telephone handset.
If your modem does support computer dialing, select Yes.
Otherwise, select No.

Does dial module

Some modems can match transmission speeds with the modem on
the remote system. Not all dial modules can support this feature
automatically.
If you select Yes for this option, the speed of the connection is
determined by the dial module. Any values you have selected for
the connection are ignored.

If you select No, then the speed you specify for the connection will
be used once a connection has been established. It is important
that this be the actual speed for the connection. You can easily
change the speed once a connection has been established by using
the Change Setup option on the Local Options menu displayed
when you press the LOCAL key.
The *DMCL dial module supports speed matching. When using
the «GENERIC dial module, DTE_DF03 or DTE_DF112, you must
specify the speed for the connection when the connection speed is
different from the speed set for the communication line.

Managing VAX Public Access Communications

Maximum
transfer rate
for commands

It is usually necessary to keep the rate at which commands are
passed to the modem low so that the modem does not lose data.
Some modems can accept commands at 100 characters per second,
but others require 10 characters per second.
The value you enter here is the maximum number of characters
per second that your modem can accept without losing data. A
value of zero is treated as 20 characters per second.
If you have problems losing data when sending commands such
as setup or when dialing, you can either reduce the transfer rate
specified here, or you can add the characters “w to introduce
pauses of half a second.

Dial command:

The dial command is used to dial the remote system when you
select computer dialing. The information you enter here depends
on the dial module you are using. The *GENERIC dial module
allows you to use VAXPAC commands within the dial command.
The *DMCL dial module requires only the VAXPAC codes %P
and %D, which represent the dial type (tone or pulse dialing) and
phone number to be dialed.

(chars/second):

When you specify the command, there are special values that you
need to understand. These are explained in Appendix D.

Start expert
dialing:

You may need to type commands directly to the modem. Use expert
dialing for this.
The modem is usually set up to allow computer dialing for outgoing
calls and automatic answering of incoming calls. This setup often
means that commands typed to the modem are not displayed on
the terminal.
If you want to use expert dial mode, specify any commands needed
to allow you to interact with the modem. Typical commands are
enable echo and display full responses.
The following example for the Digital Scholar 2400 could be used
to enable character echo:

Use this option when you want to talk by telephone with someone
at the remote site before establishing the connection.
It is sufficient with some modems to set the Data/Talk switch on
the modem to confirm a successful connection. However, some new

modems no longer have this switch and it is necessary to send a
command to the modem to go off hook.

When you specify a command to confirm connected from handset, each time you make a connection using the handset you are
prompted to press a key when you hear the high-pitched carrier
tone. When you do this, the system will try for 5 seconds to
establish a connection.

This is the control sequence that must be sent to the modem when
you want to stop the dialing sequence after it has started.
Some modems continue to dial, even though the system has
effectively hung up. Your modem documentation explains whether
this is required. If your modem resets when Data Terminal Ready
is set to OFF, then you need not define a sequence to cancel the
dial request.
For example, the control sequence to cancel a dial request on the
Digital Scholar 2400 is the following:
AB“w

Set up modem:

AB—The control character

Aw—Wait 1/2 second for modem to respond

Modems usually require some setup before they can operate with a
computer. Some modems require internal switches to be set; others
can be set up using commands. Some modems need to be set up
each time the power is turned on; others need to be set up only
once. Refer to Appendix C and your modem documentation.
The setup commands you enter here are used each time the system
starts and whenever the option Reset Communication Lines is
selected.

Managing VAX Public Access Communications

2-29

When you define the setup command, it is worthwhile to include
the characters “v at the start of the command. This causes the
interaction between the modem and the system to be displayed on
the terminal. This is useful for confirming the correct functioning
of the modem.
The following example shows the command to set up the Scholar

When you break a connection to a remote system, many modems

immediately return

to an idle state.

Some

modems,

however,

require commands to return them to the idle state. When a modem
requires reset commands,

it can often take an extra 5 seconds to

break a connection and continue normal functions.

A frequent use of the reset command is when you have chosen to
display the modem commands during computer dialing. Although
this is a good indication of the correct performance of the modem, the modem will usually have to be reset to a quiet mode of
operation; otherwise you might have problems with incoming calls.
The following example for the Digital Scholar 2400 could be used
to disable character echo. The Digital Scholar 2400 requires that
you disable echo and select abbreviated responses if you want to
support incoming calls. The characters “w specify a half-second
wait to give the modem time to respond.

Many modems allow you to choose between tone dialing and
pulse/universal dialing. For some modems this selection can be
made as part of the modem setup, while others require that you
specify this each time you dial.
You select either tone dialing or pulse dialing when you set up
your communication lines.
Enter the sequence of characters you must specify in the modem
commands when you want to specify pulse dialing.
For example, the Digital DF112 and Digital Scholar 2400 modems
require the letter P to indicate the need for pulse dialing.
To use this feature, type the characters %P as part of the modem
commands for dialing or setup, or in the phone number you specify
when defining a connection. VAXPAC replaces each occurrence
of %P with the value you enter here whenever pulse dialing is
specified for the communication line.

Use tone dialing:

Enter the sequence of characters you must specify in the modem
commands when you want to specify tone dialing.
For example, the Digital DF112 and Digital Scholar 2400 modems

To use this feature, type the characters %P as part of the modem
commands for dialing or setup; or in the phone number you specify
when defining a connection. VAXPAC replaces each occurrence
of %P with the value you enter here whenever tone dialing is
specified for the communication line.
Wait for dial
tone:

Many modems with the autodial feature allow you to enter a
character that denotes wait for a secondary dial tone. Some long
distance companies require this feature. Enter the sequence of
characters you must specify in the dial command when you want

XFR - Define Methods of File Transfer

When VAXPAC is first installed, KERMIT is the only method of file transfer
available. This means that when you want to transfer files between your system
and a remote system, the remote system must also use the KERMIT file transfer
method. If you intend to use XMODEM or some other file transfer method, use
the XFR option to define the new file transfer method. When you select XFR, the
following screen appears.

Modem Setup

This appendix discusses how to set up modems for use with VAXPAC.
There are two main areas where the requirements for operation with VAXPAC
might differ from the factory setup. One is the way that the modem accepts and
responds to commands from the system; the other is the way in which certain
modem control signals are handled.
The first section gives a general outline for setting up modems. This is followed
by sections detailing the particular requirements for the following modems:
e

Set the modem for quiet operation for incoming calls.
Many modems send a response to the local system when an incoming call
is received. On a system with VAXPAC, this can interfere with the system’s
ability to detect the line speed for the incoming call.
On a VAXPAC system, the modem must be set up so this feature is disabled.
That is, the modem must not send a message to the system when it receives
an incoming call.

Enable autoanswer.

If you allow incoming calls to your system, you must set up your modem to
support autoanswer.
|
e

Disable the speaker.
Some modems have loudspeakers for monitoring calls. Unlike terminal
operation, with VAXPAC the modem is not usually located near the person
making the connection. In this case, there is little value in enabling the
modem’s speaker.

C-—2

Modem

Setup

C.1.2

Modem Control Signals on the RS-232C Connector

In general, VAXPAC requires that modems conform to the EIA RS-232C specification.
Modems intended for operation with a terminal usually do not have the following
signals correctly set for use with VAXPAC:
e

DTR - Data Terminal Ready (RS-232C pin 20)
VAXPAC uses Data Terminal Ready (DTR) to control the modem. DTR is
normally set to ON. VAXPAC switches DTR to OFF for 5 seconds in order to
end a connection.
Some modems are initially set up to operate as if DTR were always ON. This
is incorrect for operation with VAXPAC.
VAXPAC requires that the modem be set up so that the modem returns to
its initial state when DTR goes from ON to OFF. Otherwise, VAXPAC will be
unable to hang up the phone, and you will continue to incur phone charges
after terminating the connection.

DCD - Data Carrier Detect (RS-232C pin 8)
VAXPAC uses Data Carrier Detect (DCD) to determine the state of the remote
connection. When DCD is ON, VAXPAC operates as if it were successfully
connected to a remote system. When DCD goes from ON to OFF, VAXPAC
operates as if the connection were lost.
Some modems initially are set up so that the modem always sends the ON
condition for DCD. This is incorrect for operation with VAXPAC.
VAXPAC requires that the modem be set up so that the modem sets DCD to
ON only when data carrier is present.

Modem-Specific Setup Requirements

The following sections contain information on setting up specific modems for use
with VAXPAC.
C.2.1

Setup for Scholar Plus (Digital DF242) Modem

The Digital Scholar Plus modem uses commands from the terminal to modify
its operation. There are two command modes: the Digital Modem Command
Language (DMCL) or the AT command processor, which is, as much as possible,
compatible with the HAYES AT command set found in the Hayes Smart Modem
2400. This section deals only with the DMCL command mode. For information
on the AT command

set and the Scholar Plus, see the Scholar Plus User’s Guide.

You can use VAXPAC when setting up the modem, or you can connect the modem
to the communication port on your terminal. Either way, the commands are the
same.
The factory-installed settings for the Digital Scholar Plus modems are correct
for operation with VAXPAC. There is a four-position DIP switch mounted on the
rear panel of the Scholar Plus modem; this switch is accessible from the outside.
To select the Scholar Plus factory defaults, you must set the back panel option
switches to the correct setting (see Table C-3) and turn power OFF and then ON
to cause factory defaults for all software-settable options to be read.
Note

All option switches and jumpers on the Scholar Plus modem are read:
¢

During a mode switch between AT and DMCL, or between DMCL
and AT

During an ATZ command in AT mode

During an ENAble SELF-TEST command in DMCL mode

Other Modems Supporting the AT Command

Set

Many modems offer compatibility with the AT command set used by Hayes. Be
aware that implementations of the AT command set vary among manufacturers.
Some are closely compatible with the Hayes Smart Modem 2400; others are
either closely compatible with the Hayes Smart Modem 1200 or offer a subset of
the AT command set. Read your modem documentation before proceeding with
the modem setup.
Some modems lose their current settings when the power supply is interrupted.

VAXPAC uses codes for building modem commands. These allow you to send
special characters and to monitor the progress of each command. There are three
types of codes:

Use %D in the dial command. For
example, for a Hayes compatible modem
you could enter the dial command ATD
J%DAM.
%M

Unedited phone
number

This is the complete phone number you
specify for the connection. This can be
useful for display purposes. For example,
to display the following message:
* Dialing 8-800-332-3366

You would enter the following:
At* Dialing %M *AMAJ4z.
%oP

Tone/Pulse dialing

The value for this field is determined
by the dial type you specify for the
communication

line.

Use this in the dial

command to specify tone/pulse dialing.
Most dial commands contain the sequence
%PRD.
JoW

Wait for secondary
dial

{| Use this in either the phone number or
the dial command when you want the
modem to wait for secondary dial tone.
For example, to dial out from your office
you might have to pause after dialing the
exchange. You would use this command:
9-%W-800-332-3366.

D.2

Codes for Control Characters

You can send any character to the modem. However, some characters require
a code in order to be recognized by VAXPAC. The codes for specifying control
characters can be used in all modem commands.
The most commonly used control characters can be represented using alphabetic
characters. Codes used to represent control characters are always in upper case.

D-2

Modem

Commands

for VAXPAC

Sometimes you might need to send control characters that cannot be represented
by an alphabetic character. In this case, you will have to use the numeric codes.
These are the octal values and not the decimal values for the control character.
(Octal means

a number

that is based on 8 rather than on 10.)

often used to represent characters in the ASCII character set.

Octal codes are

VAXPAC uses the following codes to represent control characters.
e

AA — 4Z: character codes 1 through 26 (decimal)

A001— “377 (octal): character codes 1 through 255 (decimal)

If you need to use the control character NUL, you should use the VAXPAC
command “a. (Section D.3 explains the codes used for VAXPAC commands.)
The codes “201—‘232 (decimal 129—-154) must be preceded by the VAXPAC
command “q except when used in the dial command for the DMCL dial module.
Table D-2 lists the codes used by VAXPAC for sending the most commonly used
control characters.

D.3

Codes

for VAXPAC

Commands

In addition to sending characters to the modem, you might sometimes need to
perform special functions. To do this, use VAXPAC commands. The codes for
VAXPAC commands always use lowercase letters.
You can use the codes for VAXPAC fields and the control characters in all modem
commands. However, there are some circumstances when the codes for VAXPAC

commands would be interpreted incorrectly.

The dial commands

for *DMCL,

DTE_DF08,

and DTE_DF112

do not support

VAXPAC commands. If you use them in the dial commands for these dial modules, they send 8-bit control characters which might give you an error.
VAXPAC command codes are acceptable in all other modem commands, as well as
in the dial command for the *GENERIC dial module.

Using the DMF32 Controller with VAXPAC

If you plan to attach a modem to one of the two modem ports (ports 0 and 1) on
a DMF32 controller on your VAX system, you should be aware that the DMF32
does not allow messages from the modem to be received until it senses carrier
from the modem. This means that any message sent by the modem while dialing
a remote system will not be returned.
Because of this limitation, the following restrictions apply when using DMF32
controllers:

While in expert mode dialing, VAXPAC will display only the characters that
you enter from the keyboard. Because the DMF32 does not display the
modem responses, you will not see the messages from the modem documented
in your modem documentation.
Also, note that the connection is set for local echo and automatic newline until
the connection has been established.

The DTE_DF03,

DTE_DF112,

and DMCL

dial modules rely on messages from

the modem to determine a successful connection. Because these messages are
not returned, you cannot select these dial modules for communication lines
using the DMF32 controller.

You should use the GENERIC dialer when using a DMF32. Note that the
following modem commands work differently when you dial out using a
DMF32. This allows existing GENERIC modem definitions to work with the
