- USING NON-WINDOWS 3270 APPLICATIONS
- ===================================
-
- This on-line document describes some specific problems you
- might encounter when running non-Windows 3270 emulation
- products with Windows 3.0.
-
-
- Starting 3270 Applications
- --------------------------
- You can start most 3270 emulator products as memory-
- resident applications (also known as terminate-and-stay-
- resident, or T&SRs). Most memory-resident applications
- are incompatible with a multitasking environment such as
- Windows, and should not be started before you start
- Windows, especially when running Windows 386 enhanced mode.
-
- However, some other applications can be started before you
- start Windows. Only attempt this if the documentation you
- received with the application specifies that it will work.
- In all other cases, start Windows first, and then run your
- emulator from a DOS Prompt, or directly from Windows
- Program Manager.
-
-
- Getting Optimal Performance with 3270 Applications
- --------------------------------------------------
- High-speed communications programs like 3270 emulators run
- successfully when you run Windows 3.0 in 386 enhanced mode.
- However, when running in real or standard mode, you must
- select the Prevent Program Switch option in the 3270
- emulator's PIF to ensure against accidental loss of your
- mainframe connection.
-
- When running in 386 enhanced mode, you will achieve the best
- results by using the following recommendations:
-
- * Start all 3270 emulation utilities from the DOS prompt.
-
- * Make sure the virtual machine can run in the background
- by setting the background bit in the virtual machine's
- Settings dialog box or in the PIF you use to start the
- machine. This should prevent your mainframe session
- from being disconnected when you run other applications.
-
- * For the best results, run all 3270 emulation
- applications full screen.
-
- * If you do run your 3270 emulator in a window, do not
- use your mouse to select text. Selecting text in this
- way will temporarily suspend your application and
- might cause your mainframe session to be disconnected.
-
- * To use file send and file receive utilities, you must
- set the Memory Required parameter for COMMAND.PIF
- so that enough memory is available to load both the
- emulator and the utilities at the same time. See the
- 3270 emulator's documentation for memory requirements
- and recommendations for system settings.
-
- * If you are running Windows in standard or real mode,
- and cannot use Windows hotkeys to switch away from your
- 3270 emulator or to copy the emulator's screen to the
- Clipboard, the emulator is probably intercepting the
- hotkeys before Windows receives them.
-
- Try using a hotkey to switch from the host session to
- the DOS session being maintained by the emulator. This
- usually causes the emulator to pass the keystrokes on
- to Windows, thereby allowing you to switch tasks.
-
- See Chapter 12, "More About Application," in the Windows User's
- Guide for more information about PIFs and memory-resident
- applications.
-
-
- IBM Personal Communications/3270 (PCS)
- --------------------------------------
- * PCS reserves specific keys for switching between the host
- and the MS-DOS sessions. These "hot keys" conflict with the
- following keys reserved for use by Windows 3.0:
-
- CTRL+ESC
- ALT+TAB
- ALT+ESC
-
- To redefine these key combinations, use a keyboard
- definition file. You can find the proper procedure in your
- PCS product documentation.
-
- * If you want your 286-based PS/2 computer configured to use
- expanded memory, you must add the following line to your
- CONFIG.SYS file:
-
- device=PCSX2EMS.SYS
-
- When you ran Setup to install Windows and chose to let
- Windows modify your CONFIG.SYS, this line was removed.
- Check the backup, CONFIG.OLD for the exact entry you must
- add.
-
- See your PCS documentation for further information on
- using PCSX2EMS.SYS.
-
- * Make sure you always unload PCS before exiting the MS-DOS
- session where PCS was initialized.
-
- * If your computer is configured so that no EMS page frame
- is available, you must prevent PCS from using expanded
- memory. Create a program information file (PIF) for
- PCS and include these settings:
-
- EMS Memory KB Required 0
- EMS Memory KB Limit 0
-
- For information about creating a PIF, see Chapter 12,
- "More About Applications," in the Windows User's Guide.
-
- * If you access PCS via a gateway on PCLP or Token Ring
- networks, you must prevent other applications from trying
- to run while PCS is running. Select the Exclusive option
- in the PIF for PCS to ensure safe operation.
-
-
- DCA IRMAX or IrmaLan
- ---------------------
- * Make sure the DCA keyboard is loaded before you start
- Windows by including the following line in your CONFIG.SYS
- file:
-
- device=kybddrv.sys -1b
-
- If you are running Windows in real or standard mode,
- you must toggle to the DOS session before using Windows
- hotkeys to switch tasks. If you do not, the driver might
- intercept keystrokes meant for another non-Windows
- application and send them to the host.
-
- * If you are running Windows in 386 enhanced mode, add the
- following line to the [386Enh] section of the SYSTEM.INI
- file:
-
- LOCAL=EXTKYBD
-
- See the on-line document SYSINI3.TXT for information about
- the procedure.
-
- * If you want to paste information from the Windows Clipboard
- to IRMAX, clear the Allow Fast Paste check box in the
- Advanced Options of the DCA's PIF.
-
-
- DCA IRMA Plus+
- --------------
- You will not be able to terminate IRMA Plus as usual. If you
- press Shift+Shift to switch to the Host, and then press Shift+F6
- to exit the emulator, you will return to the DOS prompt, not to
- the IRMA Pop-up program box. At this point, you can press
- ALT+TAB and return to Windows, but you cannot exit the emulator.
-
- To terminate properly, create the following batch file:
-
- echo off
- cls
- %1 %2 %3 %4 %5 %6 %7 %8 %9
- echo MICROSOFT WINDOWS POP-UP SUPPORT
- echo Your pop-up program has been loaded and you may activate
- it as echo you would normally. When you have finished using
- this pop-up echo program, exit it or press any key to return
- to Windows.
- pause
- command /c echo Done
-
- Name the batch file E7.BAT. Create a PIF for IRMA Plus. Enter
- e7.bat as the Program Name, and e7.com as an optional parameter.
-
- NOTE: This batch file and its associated PIF file can be used
- for other programs that terminate abnormally. Be sure
- that you enter the appropriate application name as the
- optional parameter.
-
-
- Attachmate Extra or Extra Gateway
- ----------------------------------
- * If you have problems switching away from Extra Gateway,
- answer Yes to the question "Will you be using Windows 386?"
- in the Extra Gateway configuration program. Answering Yes
- enables the -CQ option in your EXTRA.BAT file.
-
- * To ensure proper termination of Extra, clear the Close
- Window on Exit option (remove the X) in PIF for Extra.
- Alternately, you can use the E7.BAT file as explained in
- the previous topic, "DCA IRMA Plus+."
