Differences Between Previous Versions of DECnet/PCSA and
V2.0
The following list describes the differences between previous versions
of DECnetlPCSA and V2.0:
•

WorkstationlUser Configuration
For DECnetlPCSA V1.0, V1.1, and V1.2, both the workstation
and user configuration were defined by the AUTOEXEC.BAT
file.

For DECnetfPCSA V2.0, the workstation configuration has
been separated from the user configuration. The workstation
configuration is defined by the AUTOEXEC.BAT file on the key
diskette or network key disk. The user-specific configuration is
defined by the AUTOUSER.BAT file from the user's personal
directory or service.
•

DOS Enhancements
The kit supports only DOS V3.20 and V3.30. It does not support
DOS V3.10.
The KEYB utility has been renamed DECKEYB.
New Utilities:
XONXOFF provides support for asynchronous ports
that have communications devices and attached serial
printers that use the XONfXOFF protocol.
DECMODE performs the following functions:
Sets up communications port parameters, including the
setting of the modem signal control switch.
Sets up printer parameters and printer type.
Sets keyboard mode and type ahead buffer size.
Sets video mode.
DECMODE does not support code pages. Use your
native DOS for code page support.
Before you can set the keyboard mode or the type ahead
buffer size you must run KEYBRD.
Before you can set the printer type or set the
bypass modem control signals switch you must run
XONXOFF.
New Functionality:
GRAPHICS now supports the Digital LJ250 Ink Jet
Color Printer and the IBM Personal Computer Color
Printer. There is also a new qualifier, fB, that enables
background printing on color printers.

New Program Information Files (PIFs):
DECMODE.PIF
FASTOPEN.PIF (DOS V3.30 only)

Installation
There are five DECnet/PCSA Client software kits:
•

DECnet/PCSA VAXmate Client with VMS media

•

DECnet/PCSA VAXmate Client with DOS diskettes

•

DECnet/PCSA PC Client with VMS media

•

DECnet/PCSA PC Client with 5 1/4-Inch DOS diskettes

•

DECnet/PCSA PC Client with 3 1I2-Inch DOS diskettes

COMPAQ DOS 3.3 contains 3 installation diskettes. The DECnet/PCSA
client software installation prompts you to install only 2 IBM DOS
diskettes. To install the client software on a COMPAQ, you must
copy the third DOS 3.3 diskette after the DECnet/PCSA client
software installation has completed. The DECnet/PCSA client software
installation is complete when the following message is displayed:
Installation of DECnet/PCSA PC Operating Environment V2.0 completed.

To copy the third DOS 3.3 diskette, insert the correct diskette into drive
A: and type:
A:\>COPY A:*.* L:\SYSTEM\*.* IReturn)

DECnet/PCSA PC Client software requires that you run PC-DOS V3.2
or V3.3 on your client workstations to use some of the major features of
this product.
When installing DECnet/PCSA PC client software, be sure to select the
DOS Enhancements diskette for the correct version when prompted.
When installing DECnet/PCSA PC client software on PC workstations
other than IBM, follow the instructions for IBM workstations.
During the Select Keyboard part of the installation for PC workstations
with DIGITAL keyboards, the installation procedure displays the
following message:
Please run KEYBRD

You can ignore this message.
If you install client software to the file server, be sure the
DECnet/PCSA_ADMIN service is on the same node as the file server.

Once the DECnet/PCSA client software is installed, configure the
initial workstation using the Configuration Aide immediately after the
installation is complete. Before you start configuring other workstations,
you should familiarize yourself with DECnet/PCSA using the initial
workstation diskette that you built after the installation.
When running VMSINSTAL for VAXIVMS based installations, you are
required to type the name of the disk or file service that will be created.
Make sure you type a service name that does not already exist.
If you are performing an installation to a virtual disk and the message

"Insufficient disk space" is displayed, it is possible that your virtual
disk is not fully allocated. You can modify the disk and increase its
allocated size using either the MODIFY DISK command or the NET
MODIFY command.
For more information about the MODIFY DISK command, see
the VAXNMS Services for MS-DOS Administration Guide. For more
information about the NET MODIFY command, see Using Networks from
Your Workstation.

Upgrading a PCSA Workstation Hard Disk for DECnet/PCSA
Client Software V2.0
When you have DECnet/PCSA Client software Vl. * installed on your
hard disk, and you want to install DECnet/PCSA Client V2.0 software,
you must:
1. Ensure that your workstation hard disk has DOS V3.2 or V3.3
installed. To upgrade a VAXmate hard disk, see the release
note "MS-DOS 3.3 for DECnet/PCSA VAXmate Clients." To
upgrade a PC workstation hard disk, see your DOS installation
guide.
2. Delete all the files in the following directories, and the
subdirectories stored in them, then remove the directories
and subdirectories:
•

PCAPP

•

VXSYS (for VAXmate workstations)

•

ISSYS (for PC workstations)

The directories should be in the root directory on the hard disk.

To remove a directory, use the DEL command to delete all the
files in the directory. Then use the RMDIR command to remove
the directory from the hard disk. For information on using the
DEL and the RMDIR commands, see your DOS user's guide.
3. Change to the DECNET directory. Delete any files without the
.DAT extension.
4. To save your DECnet database files in the DECNET directory
from being overwritten the first time you boot the workstation,
rename any DECNET directory files with a .DAT extension to
have a .OLD extension. Later, you can restore the old version
of the DECNET .DAT files. If you do not need to save the files,
V2.0 creates new DECnet databases for you, overwriting any
existing .DAT files.
5. Boot your workstation with a V2.0 key diskette, created using
the Configuration Aide.
6. At the DOS prompt, type:
A:\>LOGIN /INIT_WORKSTATION IReturnl

7. Remove the key diskette and reboot the workstation from the
hard disk, by pressing the CtrllAlt/Del keys.
S. To restore your old versions of the DECNET databases (.DAT
files), delete any new .DAT files in the DECNET directory. Run
the NMCVT program by typing:
C:\>NMCVT x IReturnl

DECnet/PCSA Networks and DECnet-DOS V2.0
This section contains information about:
•

Creating a master node database

•

Connecting V1. * workstations to a V2.0 file server

•

Connecting a V2.0 workstation to a V1.0 or V1.1 file server

•

Creating a Master Node Database
In the DECnet/PCSA_ADMIN area, you must maintain a master node
database if you are using the Configuration Aide to build key disks. You
must create the master node database on your workstation and copy it
to the DECnet/PCSA_ADMIN area.
You may want to update the DECnet/PCSA_ADMIN account used by
the Configuration Aide with a master node database from a previous
version system, in this case convert DECNODE.DAT as described
above and then copy it to DECnet/PCSA_ADMIN.
Alternatively, you can create a master node database on your V2.0
workstation. To create the database, define each node that runs the file
server by typing:
A:\>NET DEFINE nodename nodeaddress IReturnl

Where:
nodename

Is the file server DECnet node name.

nodeaddress

Is the file server DECnet node address.

Nodes you define with the NET DEFINE command are not recognized
by the workstation until you restart it.
If you need to define other nodes, type the following NCP command
for each node you want to add:
A:\>NCP DEFINE nodeaddress NAME nodename IReturnl

See NCP HELP for additional switches and qualifiers.
Connecting VI.· Workstations to a V2.0 File Server
You can connect existing VI." workstations to a V2.0
VAXIVMS file server. You must run the upgrade procedure in
SYS$MANAGER:DECnet/PCSA_UPGRADE.COM to convert your
existing services (aliases in the UAF) to V2.0 services. See the VAXNMS
Services for MS-DOS Installation Guide for more information on the
upgrade procedure.
Connecting a V2.0 Workstation to a VI.O or VI.I File Server
You can connect V2.0 workstations to a V1.0 or V1.I file server. When
you issue the NET USE command, do not specify the user name. For
more information on the NET USE command, see the Using Networks

from Your Workstation.
8

(

The NET MOUNT ICLUSTER Command
The NET MOUNT command does not recognize the ICLUSTER
qualifier. Instead of the ICLUSTER qualifier, use the IQUERY qualifier.
For example:
NET MOUNT /q
NET MOUNT \\node%service%username * Iq

Using the NET ERROR Command
If you use the NET ERROR command when the first virtual disk drive is

not connected, the NET ERROR command fails. You must be connected
to the first virtual disk drive to use the NET ERROR command.
Recalling NET Commands
After you issue a NET command, you cannot recall the command just
typed. This affects only the command editing buffer used by DOS.
PC Workstations and Remote Boot

(

PC workstations with DEPCAs installed can take advantage of the
remote boot capabilities of DECnet/PCSA V2.0. When the workstation
is booted from the network, the remote boot image uses the upper 17
Kbytes of memory. The total memory size as reported by utilities such
as CHKDSK will be off by 17 Kbytes.
PC Workstations and Connecting to the Network
If you are unable to make network connections on an AT-class
workstation that does not have a real-time clock, type the following
command at the DOS prompt:
A:\>NCP SHOW LINE COUNT [Returnl

Check the Seconds Since Last Zeroed value. If it is zero or if, after you
repeat the command, the Seconds Since Last Zeroed value has not been
updated, include the following line in the AUTOEXEC.BAT file before
the first NET START command:
SCHPC Is

(
9

This command forces the scheduler to use the system clock.
NOTE
During remote boot, an AT-dass workstation always uses the
system dock.

Configuration Aide
This section contains information about:
•

Known problems

Upgrading the Application Database
If you have a previous version of the application database, you can

convert it to a V2.0 application database as follows:
1. Copy the CAAPPLST.DAT file from PCAPP on your V1.0, Vl.l,
Vl.2 system to DECnet/PCSA_ADMIN.
2. Delete the CADATA.DAT file in the DECnet/PCSA_ADMIN
area.
When you next run the Configuration Aide, it automatically
converts the V1.0, V1.1, V1.2 database to a V2.0 database.
Manually Updating your System Directory
To manually update your system directories on the hard disk:
1. Transfer a DOS V3.2 or DOS V3.3 system to the hard disk.
2. Boot the workstation from its key disk.

'- /

Create the system directories on the workstation hard disk by
typing:
A: \>MKDIR C:\SYSTEM OReturnl
A: \>MKDIR C:\DECNET IReturnl
A: \>MKDIR C: \WIN IReturnl
A: \>MKDIR C:\WIN\dir IReturnl

Where:
dir

Is the MS-Windows directory for your workstation.
There may be more than one MS-Windows directory. For
example, C:

If you are not running MS-Windows, you do not need to create

the WIN directories.

4. Type the following COPY commands to transfer the system
files:
A: \>COPY L:\SYSTEM\*.* C:\SYSTEM l~~!~r~
A: \>COPY L:\DECNET\*.* C:\DECNET IRe~~
A: \>COPY L:\WIN\dir C:\WIN\dir ~etur~

(

Where:
dir

Is the MS-Windows directory for your workstation.
There may be more than one MS-Windows directory. For
example, C:

You can skip the last COpy command if you do not require
MS-Windows.

5. Copy the datalink and session files to your hard disk:
A:\>COPY A:\DECNET\DLL.EXE C:\DECNET lR~tu!nJ
A:\>COPY A:\DECNET\SESSION.EXE C:\DECNET [Return I

If you start your workstation from your hard disk, follow the procedure

in the next section to update the start-up files.
Manually Updating your Start-up Files
To manually update start-up files on the local hard disk:
1. Transfer a DOS V3.2 or DOS V3.3 system to the hard disk.
2. Boot the workstation from its key diskette.

(
11

3. Create the DECNET directory on the workstation hard disk by
typing:
A:\>MKDIR C:\DECNET IReturnl

4. Type the following COPY commands to transfer files from your
key diskette.
A:\>COPY A:\*.* C:\*.* IReturnl
A:\>COPY A:\DECNET\*.* C:\DECNET IReturnl

Now you can start the workstation from the hard disk.
Configuring PC Workstations without LI<2S0 Keyboards
When you use the Configuration Aide to configure a PC workstation
that is running DOS 3.3 and does not have an LK250 keyboard, the
Configuration Aide adds the following line to the AUTOEXEC.BAT file:
KEYBRD

If you do not have an LK250 keyboard connected to the PC workstation,
edit the AUTOEXEC.BAT file and delete this line.
AUTO LOGIN
If there is no AUTOUSER.BAT file in your personal virtual or file

service, the first time an AUTOLOGIN is performed, a message is
displayed that tells you to type the command:
LOGIN /INIT_USER

If you type the preceding command and there is a LOGIN. COM file in
your personal virtual or file service, the AUTOLOGIN command runs
the LOGIN.COM file instead of the LOGIN.BAT file in the \SYSTEM
directory on drive L:. You should use the LOGIN.BAT file in the
\SYSTEM directory. To do this, type:
L:\SYSTEM>LOGIN /INIT_USER dry IReturnl

Where:
drv

Is the drive or path name for the directory in which the USER. BAT
file is stored.

The Configuration Aide AUTOLOGIN option is not supported on
DECnet/PCSA Vl.0, V1.1 or V1.2. If you are using a V2.0 client and
your personal directory is stored on a server running DECnet/PCSA
V1.0, V1.1, or V1.2, you cannot select the Configuration Aide
AUTOLOGIN option.
If you try to use AUTOLOGIN to connect to a DECnet/PCSA V1.0 or

V1.1 server, the following message is displayed:
NET818: Network name not found

Defining Maximum DECnet Links
When using the Configuration Aide, you specify the maximum DECnet
links to define the number of remote hosts to which a workstation can
connect. If the maximum DECnet links is greater than 4, add the IS:n
qualifier to the NET START RDR command in the AUTOEXEC.BAT
file. For example:
NET START RDR /S:n

Where:
Is the number of DECnet links, which is equal to the Executor
Characteristics Maximum Unks setting.

MS-Windows
This section contains information about:
•

Using the Calendar application

•

Virtual disk drive icons

•

The XCOPY Command

•

Deleting files

•

Clipboard and COMPAQ Deskpro

•

The VT220 terminal emulator

Using the Calendar Application
When filling in dates using the Calendar application in 12-hour mode,
you cannot use a 24-hour time format.
When setting time formats, you must type AM and PM in uppercase.
~•...

Virtual Disk Drive Icons
If you try to connect to a drive icon for a virtual disk from which you are

disconnected, MS-Windows displays an error message.
After you disconnect from a virtual disk, the MS-DOS Executive window
continues to display the virtual disk drive icon. The virtual disk drives
are accessed by a device driver that registers four drives. Because
MS-Windows gets its drive information through MS-DOS, there is no
information about connections.
The XCOPY Command
Do not use the XCOPY command in MS-Windows. XCOPY uses
an old FCB method of determining source and destination drives.
WINOLDAP, which is a standard applications interface to MS-Windows,
does not copy command arguments to FCBs.
Deleting Files
MS-Windows works differently from DOS when deleting files with
different attributes. In DOS, you cannot delete files with either the
hidden attribute or the read only attribute set. The MS-Windows
MS-DOS Executive deletes files with the hidden attribute set, but does
not delete files with the read only attribute set. For information on the
file attributes, see your DOS reference manual.
Clipboard and COMPAQ Deskpro
On a COMPAQ Deskpro workstation, you cannot transfer screen data
from a standard application to the MS-Windows Clipboard.
The VT220 Terminal Emulator
This section contains information about:

•

The SYSTEM: command

•

Error log files

•

U sing Cut and Paste to an EDT Session

•

Defining UDKs

•

Modem Control

•

Multiple VT220 Sessions

(

The SYSTEM: Command
To use the SYSTEM command from a script, there must be 150
Kbytes of memory free and available. To determine the amount of
free memory, select the ABOUT option from the MS-DOS Executive
window System menu.
Error Log File
If there is more than one instance of the VT220 emulator processing

a script at one time, the script error log file name changes from
ERROR.LOG to ERROR%.LOG, where % is the VT220 instance number
for any instance after the first.
Using Cut and Paste to an EDT Session
When pasting a large buffer to an EDT editing session, characters
sometimes get lost. The EDT editor cannot receive and process the
rapid firing of characters while updating the screen.
To avoid losing characters, before starting to cut and paste, type:
$ SET TERM!HOSTSYNC liiSlurnl

(

If characters are still lost, either:

•

Reduce the baud rate

•

Before pasting, set EDT to line mode rather than command
mode

Defining UDKs
You can define UDKs F6 - F20 using the 7-bit and 8-bit device control
string DECUDK. Using the VT220 emulator Set-up, you can define the
UDK to require or not require use of the Shift key.
When you use the VT220 emulator Set-up to set the UDK SHIFT state,
the state you select affects how you use DCL function keys defined by
the VAX/VMS DCL DEFINE/KEY command. If you set the UDK SHIFT
state to Shifted, you can use the DCL function key without using the
Shift key. If you set the UDK SHIFT state to Unshifted, you can use the
DCL function key by first pressing the Shift key.

Modem Control
The MS-Windows VT220 Terminal Emulator does not support full
modem control.
The MS-Windows operating environment does not support preemptive
scheduling, which means that the precise timings required for full
modem control cannot be guaranteed to be accurate.
Listed below are the known problems with full modem control for the
MS-Windows VT220 terminal emulator:
•

If DSR comes on and CD does not come on within 30 seconds,

the terminal should initiate a disconnect.
•

If CD is on and then dropped, the terminal should wait either

2sec or 60ms (based on the Set-Up parameter) for CD to come
back on. If CD does not come back on, the terminal should
initiate a disconnect.
•

If DSR is off, a disconnect should turn DTR off for 220ms and
then back on. If DSR is on, a disconnect should turn DTR

off for 5sec and then turn DTR back on. The VT220 terminal
emulator turns off DTR for 183ms, which is too short.
SETHOST supports control of asynchronous modems.
Multiple VT220 Sessions
Do not set up the WIN .INI file to load more than two sessions of the
VT220 terminal emulator when MS-Windows starts. If the WIN.INI file
loads three VT220 sessions and runs one of the sessions when
MS-Windows starts, unpredictable results can occur. When all sessions
are opened as windows, two sessions can receive and transmit the same
data.
To avoid this problem, load additional VT220 sessions after
MS-Windows starts.

Updating Your Hard Disk with DOS V3.3
If you have a VAXmate workstation with a hard disk that contains

MS-DOS V3.1, and you want to install MS-DOS V3.3 to the hard disk,
you must:

1. Backup your hard disk startup partition using the BACKUP
command.

(

~..

-,/

2. Boot the MS-DOS system disk supplied with the kit containing
MS-DOS V3.3.
3. Run SYS from drive A: to your hard disk startup partition
(usually C:)
A:\>SYS c: IRel~~

If no errors occur, your hard disk now has the MS-DOS 3.3

operating system on it. Delete all MS-DOS 3.1 files from your
hard disk and copy the MS-DOS 3.3 utilities to the directory on
your hard disk where you store MS-DOS utilities. For example:

IR61urrlj
\SYS;rEM\ *." [E~iur;~J

A:\>DEL C:\SYSTEM\*.*
A: \>COPY A: \ *. * c:

If an error occurred, continue with Step 4.
If no error occurred, continue with Step 6.

4. Format the partition by typing:
A: \>FORMAT c: Is [~e!urnJ
A:\>MKDIR C:\SYSTEM L~~uf~l

(
17

5. Copy the DOS utilities from drive A to the system subdirectory
on drive C by typing:
A:\>COPY A:\*.* C:\SYSTEM\*.* IReturnl

6. Then type:
A:\>ATTRIB C:\SYSTEM\*.* +R /s IReturnl

Now restore the files using the RESTORE command. Be sure to
use the IP qualifier and answer "No" to all prompts requests to
write over existing files.
7. Copy COMMAND. COM as follows:
A:\>COPY A:COMMAND.COM c: IReturnl

The COMMAND.COM File
The default DOS environment size is 512 bytes.
The CONFIG.SYS File
When starting the workstation, if the CONFIG.SYS file contains an
invalid command, the line after the invalid command is skipped. The
system displays an error message indicating that the CONFIG.SYS file
contains an invalid line.
The DISKCOMP Command
Using the DISKCOMP command, you can compare virtual disks up to
1.2 Mbytes in size.
The DISKCOPY Command
Using the DISKCOPY command, you can copy virtual disks up to 1.2
Mbytes in size.
The XCOPY Command
The XCOPY command does not work under MS-Windows.

COMPAQ and PS/2 Workstations and Configuration Aide
Thi!'l section contains information about:
•

Configuring PC workstations without LK250 keyboards

•

Configuring PS/2 workstations

•

COMPAQ and PS/2 Model 30s and Ethernet Controllers

•

Adding Partitions to the COMPAQ Hard Disk

Configuring PC Workstations without LK250 Keyboards
When you use the Configuration Aide to configure a PC workstation
that is running DOS 3.3 and does not have an LK250 keyboard, the
Configuration Aide adds the following line to the AUTOEXEC.BAT file:
KEYBRD

If you do not have an LK250 keyboard connected to the PC workstation,

edit the AUTOEXEC.BAT file and delete this line.
Configuring PS/2 Workstations
The Configuration Aide creates a \DRV directory that contains all system
files for running MS-Windows. For the PS/2 family of PC workstations,
you must copy the following files and give them the following names:
Files

New file name

CGA.LGO

IBMPS230.LGO

CGA.GRB

IBMPS230.GRB

EGAHIRES.GRB

IBMPS250.GRB

EGAHIRES.LGO

IBMPS250.LGO

Use the COPY command to copy and change the file names. For
example:
A:\>COPY CGA.LGO IBMPS230.LGO IReiurn]

After copying the files in the \DRV directory, you should have both
copies of each of these files.

COMPAQ and PS/2 Mode130s and Ethernet Controllers
The DECnet/PCSA network software uses the IIRQ - 5 as the default,
and the Configuration Aide does not have an option that lets you
change the IIRQ setting. If you are using a supported third-party
Ethernet controller with an IRQ other than 5, you must:
1. Create the key diskette.
2.

Determine the correct /IRQ setting for the jumper location on
your third-party Ethernet controller. See your Ethernet controller
hardware documentation.

3. Edit the AUTOEXEC.BAT file to change the first NET command
to:
NET xxx yyy /IRQ:

Where:
xxx

Is either the START command or the SET EXECUTOR
command

yyy

Is the network software you want to start: RDR, for the
redirector, or LAD for the virtual disk software

IRQ:n

Is the correct IRQ setting for your Ethernet controller

For example:
NET START LAD /IRQ:3

If the first NET command is NET START LAD, you need to change only

this command.
If the first NET command is NET SET EXECUTOR, you need to change

this command and the NET START RDR or NET START LAD.
For more information on editing the AUTOEXEC.BAT file, see Using

Networks from Your Workstation.
Adding Partitions to the COMPAQ Hard Disk
To add an additional partition to the hard disk, you must load an
additional driver.
The Configuration Aide adds all additional drivers to the end of the
CONFIG.SYS file. The Configuration Aide loads LADDRV.SYS on
drive D. The additional driver required for the additional partition also
tries to load to drive D and the system hangs.
/

\. .J

(

After the Configuration Aide creates the CONFIG.SYS file, edit the
file and move the line for the additional driver to the line before the
LADDRV.SYS command line. The system then loads the partition drive
before the LAD drives.
For example, if you are adding one extra partition to the hard disk,
the total number of partitions on the hard disk is two. From the
Configuration Aide, with the Disk Information option in the Workstation
Menu, select a hard disk with two partitions. In the Start-up Drivers
option in the Workstation Menu, add the COMPAQ driver that adds
the extra partition. You must copy this driver to the boot device before
booting.
For example, the old CONFIG.SYS can include the following
commands:
BUFFERS=30
DEVICE=LADDRV.SYS
DEVICE=partition driver

The new CONFIG.SYS would change to:
BUFFERS=30
DEvICE=partition driver
DEVICE=LADDRV.SYS

For more information on drive assignments, see Using Networks from
Your Workstation.

DOS Enhancements for DECnet/PCSA PC Clients
This section contains information about:
•

Using the FORMAT command with virtual disks

•

Using the DISKCOMP and DISK COPY commands with virtual
disks

•

Using the DISKCOPY command with virtual disks

•

Using the BACKUP command with the IF qualifier

•

Using the DECMODE Command on a COMPAQ Workstation

•

The SETHOST Keyboard Buffer

Using the FORMAT Command with Virtual Disks
Do not use the FORMAT qualifiers 11/4/8/S/B/N/T with virtual disks.
Using the DISKCOMP Command with Virtual Disks
Do not use the DISKCOMP or DISKCOPY commands on virtual disks
greater than 1.2 Mbytes.
If you use the DISKCOMP or DISKCOPY commands with a virtual disk

as a parameter, DOS prompts you to insert the diskette into the virtual
disk drive. Press the Return key, and the DISKCOMP or DISKCOPY
command continues.
Using the BACKUP Command with the IF Qualifier
If you use the BACKUP command with the IF (format destination)

qualifier and you insert a destination diskette that has a write-protect
tab, the BACKUP command stops and displays the following error
message:

Target can not be used for BACKUP.

Be sure to remove the write-protect tab from any diskette you use as the
destination diskette for the BACKUP command.
Using the DECMODE Command on a COMPAQ Workstation
DECMODE-When you use the DECMODE command to put a
COMPAQ 8086 or COMPAQ 80286 in one of the following graphics
video modes, the results are unpredictable:
•

C0320

•

BW320

•

BW640

The first column on the screen can disappear after the screen has been
filled up once or the screen can be filled with miscellaneous data. In
these cases, you cannot user graphics video mode.
\.

The SETHOST Keyboard Buffer
When you start SRTHOST, the keyboard buffer size must be 16 or less.
If the keyboard buffer size is greater than 16, you must run the following

command before running SETHOST:
A: \>DECMODE ,16 IReturnl
