Rules of Thumb
NetWare 3270 LAN Workstation for DOS v3.0
December 4, 1992
NetWare 3270 LAN Workstation for DOS is terminal and printer emulation
software that provides access to SNA mainframes and IBM AS/400
minicomputers for PC, PS/2, and compatible workstations on a NetWare LAN.
Workstation access to the host is provided through a NetWare communications
server running NetWare for SAA.
NetWare 3270 LAN Workstation for DOS v3.0 supports up to five concurrent
host display or printer sessions, and provides an Advanced Program-to-
Program Communications (APPC) interface for NetWare LU6.2 support. It also
includes file transfer and keyboard mapping software.
INSTALLATION REQUIREMENTS
3270 LAN Workstation for DOS v3.0 includes an installation utility. The
workstation software is shipped on a number of installation disks. The
installation disks require a high density floppy disk drive.
For information on installing NetWare 3270 LAN Workstation for DOS, see
Chapter 1 in the NetWare 3270 LAN Workstation for DOS Configuration Guide.
Disk Space Requirement
3270 LAN Workstation for DOS v3.0 software requires 2.5MB of disk space.
Conventional Memory Requirements
- Depending on the workstation's configuration, the minimum amount of
memory required for one model 2 session (configured for base attributes)
is 154KB.
- The memory required for each additional model 2 session is 4KB.
- Extended attributes require 18KB additional memory.
These memory requirements can be significantly reduced if you configure
your workstation to use expanded memory, extended memory, or Upper Memory
Blocks (UMBs).
CONFIGURATION FILE CONVERSION
3270 LAN Workstation for DOS v3.0 includes a configuration file conversion
utility. You can use the Convert utility to convert previous versions of
workstation configuration files to v3.0 configuration files. For
information on converting your old configuration files, see Chapter 1 in
the 3270 LAN Workstation for DOS Configuration Guide.
Converted 3270 LAN Workstation for DOS v2.0 configuration files are
compatible with v3.0. However, if you want to use any of the v3.0
workstation features, you must run the workstation configuration program
(WSCONFIG) against these files to configure the new features.

MEMORY MANAGEMENT RECOMMENDATIONS
You can configure your workstation to use any combination of the following
memory management options:
- Expanded memory
- Extended memory
- Expanded memory plus upper memory blocks (UMBs)
Novell recommends this memory configuration.
- Extended memory plus UMBs
- UMBs (without expanded or extended memory)
Your workstation memory configuration must be supported by the appropriate
configuration statements in your CONFIG.SYS file. Without the correct
combination of statements in your CONFIG.SYS file, your workstation cannot
implement the workstation's memory configuration, even if the appropriate
memory manager software is installed.
Configuration Parameters Required for the CONFIG.SYS File Tables 1 through
3 show a set of basic statements to include in your CONFIG.SYS file. The
tables provide statements that support the five memory configurations
listed above for each of three memory management products: QEMM and the
memory management software included with DR DOS 6.0 and MSDOS 5.0. Please
refer to the documentation that accompanies the memory management software
you are using.
Tables 1 through 3 do not show drive or path specifications in the
CONFIG.SYS statements. You must customize the statements in your
CONFIG.SYS file with the appropriate drive and path specifications for your
system.
IMPORTANT: Use the information provided in Tables 1 through 3 if you are
implementing memory management with NetWare 3270 LAN Workstation for DOS
for the first time. If your site has already implemented memory
management, the statements shown in the tables may not be applicable.
Table 1 DR DOS 6.0 Memory Management Parameters for the CONFIG.SYS File
Memory Configuration DR DOS 6.0
Expanded only DEVICE=EMM386.SYS /F=AUTO *(1)
Extended only DEVICE=EMM386.SYS /F=NONE *(2)
Expanded + UMB DEVICE=EMM386.SYS /F=AUTO *(1)
Extended + UMB DEVICE=EMM386.SYS /F=NONE *(2)
UMB only DEVICE=EMM386.SYS /F=AUTO *(1)
*(1) /F=AUTO places the expanded memory frame in the first available 64KB
block. *(2) /F=NONE deallocates the expanded memory frame and therefore
makes available 64 KB of memory.

Effects of SUPERPCK on Extended Memory
Super PC-Kwik (SUPERPCK) is a disk caching program provided by DR DOS.
When you invoke SUPERPCK, the program loads the PC-Kwik disk cache. (For
details on the syntax of SUPERPCK, see the DRDOS6 Instant Reference.)
SUPERPCK's /EM+ switch enables the disk cache to access extended memory.
When you use the /EM+ switch, SUPERPCK uses all available extended memory.
If you configure the workstation to use extended memory while SUPERPCK's
/EM+ switch is enabled, the workstation control program (WSLAN) terminates
and displays the following message:
***External Memory Failure***
System Extended Memory driver (XMS) not installed
****Control Program is no longer resident****
If termination occurs, use WSCONFIG to remove extended memory from the
configuration; then reload WSLAN.
PRINTING RECOMMENDATIONS
This section presents information regarding hardware printing and
redirectable printing.
HARDWARE PRINTING
When you select Hardware Printing from the WSCONFIG Printer Options menu,
NetWare 3270 LAN Workstation for DOS loads its own print driver and directs
print jobs to a printer attached to one of the workstation's parallel or
serial printer ports.
Hardware printing uses interrupts to achieve higher performance. If you
select Hardware Printing, be sure that the interrupt request lines assigned
to the serial or parallel ports do not conflict with an existing I/O
interface card.
Printing Screens While Configured for Redirectable Printing
When you select Redirectable Printing from WSCONFIG's Printer Options menu,
NetWare 3270 LAN Workstation for DOS first directs print jobs to parallel
printer ports LPT1, LPT2, or LPT3; WSLAN then redirects the jobs (via the
CAPTURE command) to a network printer.
If you are redirecting print jobs to a NetWare LAN printer and you want to
print screens, you must issue the CAPTURE command before you print. As
explained in the following sections, the CAPTURE command syntax varies
depending on whether you are sharing the print screen port with a DOS
session.
When a DOS Session Is Configured
Issue the CAPTURE command as follows:
- Set the correct parallel port number with the LOCAL parameter.
- Set a timeout value with the TIMEOUT parameter.
- Specify the NOAUTOENDCAP parameter.
You can adjust the timeout value by examining your printer output. If the
printer output is segmented into several jobs, increase the timeout value.
If several jobs are accidentally combined in one printout, decrease the
timeout value.
We recommend an initial timeout value of 30 seconds.
The following example shows a CAPTURE command with the parallel port set to
LPT1, NOAUTOENDCAP specified, and the timeout value set to 30 seconds:
CAPTURE LOCAL=1 NOAUTOENDCAP TIMEOUT=30
When a DOS Session Is Not Configured
When you want to print screens and have configured WSLAN to not include a
DOS session, issue the CAPTURE command with the parameters set as follows:
- Set the CAPTURE command with the AUTOENDCAP parameter on.
- Turn the TIMEOUT parameter off.
The following example shows a CAPTURE command with the parallel port set to
LPT1, the AUTOENDCAP parameter set to on, and the TIMEOUT parameter set to
off: CAPTURE LOCAL=1 AUTOENDCAP TIMEOUT=0
ACCESS SERVER SUPPORT
NetWare Access Server software provides remote and local users with the
services of a NetWare LAN. The NetWare Access Server provides LAN
resources to a remote or local LAN attached IBM PC, PS/2, or compatible or
an Apple Macintosh.
NetWare Access Server supports up to 16 users simultaneously by using a
386 or 486 CPU to create virtual machines. When remote or local users
connect to the Access Server, they can use one or more of the virtual
machines to run DOS applications and access the resources of the LAN.
Because all processing is handled by the NetWare Access Server, only screen
updates and keystrokes travel over the communication medium. If you are
using NetWare Access Services v1.22, you must obtain PTF355.ZIP (soon to be
available in Library 9.
We suggest you use keyboard buffering when running WSLAN over NetWare
Access Services. NetWare Access Services does not support WSLAN's automatic
ASCII code page detection feature. For information on toggling code page
detection on and off, see Chapter 6 in the NetWare 3270 LAN Workstation for
DOS Configuration Guide.
Remote users running NetWare 3270 LAN Workstation for DOS can access the
NetWare Access Server from a remote PC with OnLAN/PC or a Macintosh with
OnLAN/Mac that connects to the NetWare Access Server via asynchronous
modems.
Local users running NetWare 3270 LAN Workstation for DOS can access the
NetWare Access Server from a local PC with OnLAN/PC or a Macintosh with
OnLAN/Mac that connects to the NetWare Access Server via IPX.
NetWare 3270 LAN Workstation for DOS v3.0 does not support access to the
NetWare Access Server via a dumb ASCII terminal.
NetWare Access Services supports SEND-RECEIVE file transfers and 3270 Model
2 emulation. All the sessions must be configured for base data stream
support. NetWare Access Services does not support extended attributes
(including APL characters).
If you have a VGA or EGA monitor and your session is disconnected while you
are running the Keyboard Definition Utility (KEYDEF) in NetWare 3270 LAN
Workstation for DOS v3.0 over the NetWare Access Server v1.22, run NASGEN.
Then configure NetWare Access Services to convert VGA or EGA to CGA.
IMPORTANT: Do not run the NetWare Access Services conversion utility to
convert VGA or EGA to CGA with a monochrome or CGA Access Server.
Running WSLAN Under Windows
Novell supports the following functions of NetWare 3270 LAN Workstation for
DOS in a DOS box in Windows v3.1:
- Model 2 emulation
- File transfer
- Redirectable printing
- Hardware printing
- Extended memory
NOTE: Novell cannot guarantee that NetWare 3270 LAN Workstation for DOS
will operate in all environments or all configurations.
When running the workstation control program (WSLAN) in a DOS box under
Windows, observe the following restrictions:
- When running WSLAN in a DOS box under Windows, you must exit WSLAN
before returning to Windows. To exit WSLAN, press <Alt+End> or enter
WSEXIT at the command line. - To fully use a DOS session under Windows,
you must load WSLAN from the DOS prompt not from a Program Information
file (PIF) or via the RUN command.
- If you do not have the most current version of VIPX.386 when you bring
up WSLAN under Windows, you may receive the following message:
Your version of VIPX.386 for Windows is out of date. If you continue
to run WSLAN with that version of VIPX.386, problems could occur.
Contact your Novell dealer for a later version.
- Do not run WSLAN configured for expanded memory or upper memory blocks
(UMBs). Doing so causes the workstation to behave unpredictably. You can
run WSLAN configured for extended memory.
- The Windows DOS box is not fully DOS compatible and does not support
the characters used in extended attributes (including APL characters).
If you run WSLAN with extended attributes in a DOS box as a window
(instead of running WSLAN in full-screen mode), the Operator Information
Area (OIA) is corrupted.
- Run the NetWare 3270 Vector Graphics Option only in full screen mode.
If you attempt to display a 3270 session when you run WSLAN with the
Vector Graphics Option in a DOS box as a window, you receive the
following error message: You cannot run this application while other
high resolution applications are running full screen. The application
will be suspended until a low resolution or text application is
running full screen. Check the PIF settings to ensure they are correct.
Running WSLAN Under IBM OS/2 v2
We do not recommend running NetWare 3270 LAN Workstation for DOS in a DOS
box under IBM OS/2 v2.0. If you do so, you may experience unpredictable
results.
Model 5 Emulation Support
To accomplish model 5 emulation with any EGA or VGA adapter, the monitor
must support the display adapter's horizontal and vertical scan rates. The
combination of horizontal and vertical scan rates determines your monitor's
resolution.
The table below lists Novell's model 5 drivers designed to implement the
model 5 support of the listed chip sets and their corresponding display
adapters. Refer to the documentation that accompanies your graphics
adapter for more information on compatible monitors.
Only the Tseng Lab chip set (requiring no driver) and the M5PS2 and M5xPS2
items pertain to current adapters and monitors.
The remaining rows refer to older hardware that is no longer purchasable
but that may be in your installed base.
Novell continues to develop additional model 5 drivers that support the
major chip sets found on current adapters. To acquire the most recent
drivers, check NetWire NOVLIB Library 9 for the most current program
temporary fix (PTF) for NetWare 3270 LAN Workstation for DOS (none yet as
of November 25, 1992).
