TokenExpress(TM) Adapter: Driver Installation, IBM - 3270 Connectivity
IBM 3270 CONNECTIVITY
This file contains instructions for installing the TokenExpress adapter
driver. It contains information specific to the installation and
operation of Intel's TokenExpress adapters only. Refer to the
appropriate Network Operation System documentation for any NOS-specific
questions or other information.
These instructions apply to Release 5.0 of the software.
Using Intel TokenExpress adapter DLC drivers with IBM 3270
emulation/communication programs.
General installation guidelines
1. Create a directory on your system hard disk for the TokenExpress
adapter DLC drivers.
2. Insert the Intel driver diskette #2 into drive A:.
3. Copy the Interrupt Arbitrator (A:\IBM\DOS\OC01IA.SYS) and the DLC
driver (A:\IBM\DOS\OC02DLC.SYS) to the newly created directory.
4. Edit your CONFIG.SYS file and add the following lines:
FILES=20
BUFFERS=50
LASTDRIVE=x (where 'x' = the designator of the last local drive
on your PC - e.g. E or F or ...)
DEVICE=(full_path)\OC01IA.SYS
DEVICE=(full_path)\OC02DLC.SYS
* (full_path) consists of the drive designator followed by the name
of the directory into which the DLC driver and interrupt arbitrator
have been copied. Refer to steps 1 and 2 above.
5. Copy the A:\IBM\DOS\OC01INII.COM file into the directory on your
hard disk containing the IBM 3270 emulation program you are using.
Note: Both the Interrupt Arbitrator (OC01IA.SYS) and the DLC
Driver OC02DLC.SYS) have optional parameters which can be specified
during installation. Refer to the PC LAN installation file for
additional information.
Special Guidelines When Using the IBM PC 3270 Emulation Program
If your PC is configured as a 'Standalone Workstation,' the following
guidelines apply:
* The default I/O address (A20) must be used.
* Interrupt level 2 or 3 must be used.
Any other restrictions described in the IBM PC 3270 Emulation Program
documentation also apply.
Special Guidelines When Using the IBM Personal Communications/3270
Program Version 1.0x (used with IBM's Windows Connection product) and
IBM Personal Communications/3270 Program Version 2 (DOS-only setup).
If your PC is configured as a workstation using the DLC interface, the
following guidelines apply:
1. The default I/O address (A20) must be used.
2. Interrupt level 2 or 3 must be used.
3. The program OC01INII.COM must be executed immediately *BEFORE* the
Personal Communication/3270 program is started. Otherwise, the
PC/3270 program aborts with an error indicating that the adapter or
driver is missing.
When the PC/3270 program is configured (installed), a batch file
for starting the program is created. This batch file should be
invoked from within another batch file which executes OC01INII.COM.
The following sample batch file (3270.BAT) is contained on the
Intel driver diskette in the \IBM\DOS directory.
3270.BAT:
@rem Beginning of sample batch file
@echo off
OC01INII
rem Now continue with the original batch file
rem doing the actual 3270 emulation (in this
rem example PC3270.BAT):
PC3270
rem End of sample batch file
Note: If you have installed an RPL PROM for the TokenExpress
16/4 adapter, the previous guideline (#3) does not apply.
Any other restrictions described in the IBM Personal Communications/3270
documentation also apply.
Special Guidelines When Using the IBM Personal Communications/3270
Program Version 2 With Windows 3 in Standard Mode (Windows 3 setup).
Certain precautions are necessary when using the IBM Personal
Communications/3270 if Windows is run in *STANDARD* mode. (386+
machines with 2 MB of memory or more default to ENHANCED mode when
running Windows).
1. The Interrupt Arbitrator (OC01IA.SYS) v1.09 or later must be used.
Earlier versions do not work. If you do not have v1.09 or later,
the IBM equivalent program (DXMA0MOD.SYS) should be used.
2. The Personal Communications/3270 installation utility attempts to
modify the CONFIG.SYS file after locating the entry which loads the
IBM DLC driver (DXMC0MOD.SYS). (DXMC0MOD.SYS is IBM's counterpart
to the TokenExpress DLC driver OC02DLC.SYS). For example:
:
device = (path)\DXMC0MOD.SYS | original
device = (path)\PCS802.SYS V=N | <--- inserted
:
If unable to locate the DXMC0MOD.SYS entry, the installation
utility leaves the CONFIG.SYS file unchanged, issues an error
message, and terminates. You can work around this problem by
either:
a. Renaming OC02DLC.SYS to DXMC0MOD.SYS and modifying the
CONFIG.SYS file to reflect the change,
*OR*
b. Inserting a dummy entry
:
device = DXMC0MOD.SYS
:
Into the CONFIG.SYS file before invoking the PC/3270
installation utility. The dummy entry should be inserted right
after the entry which loads the TokenExpress DLC driver
(OC02DLC.SYS).
Support for the IBM 3270 Workstation Program
The TokenExpress adapter driver does not include support for the IBM
3270 Workstation Program.
