    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.
