Examples of such software include PlayAtWill and EZPlay from IBM, Phoenix Card Manager Plus from Phoenix Technologies Inc., CardSoft from SystemSoft Corporation, and CardWare from Award Software, Inc. The Modem Configuration and Diagnostic Software works under MS-DOS 5.0 or higher, PC-DOS 5.0 or higher, or OS/2 2.1 or higher. The modem enabler requires that either your system have a PCMCIA adapter which is compatible with the Intel 82365SL or that Card and Socket Services software is present. See the manual for details. If you are installing the enabling software under DOS, you will need to determine what COM ports are available for use. A COM port provides the means by which a computer can access a serial device, such as a modem. By default, the installation program uses COM2, but can be changed during or after the installation. Consult the manual that came with your computer for more information about com ports and system configuration. ====================================================================== 2) Supported Computers The following computers have been tested with this software. Acer* Anywhere 386SL Ambra*BNC 4523 AST* Power Exec 386 & 486 Data General Walkabout 386SL Dell* 320 SLi Gateway 2000* IBM* Thinkpad 350, 360, 500, 710T, 720, 750, 755 INTEL* Adapter for ISA bus computers NCR* 3170, 3180 NEC* UltraLite Versa Toshiba* 3400CT, T4500, T4600 Unisys* 325SL Zenith* Z-Lite 320L ====================================================================== 3) OS/2 2.1 - Fixes for VCOM.SYS and COM.SYS At the time of General Availability of this product (October, 1993), Version 2.1 of OS/2 required a fix in order to properly enable the modem configuration software. The fix is contained on this diskette in the /OS2FIX subdirectory. Before applying the fix, be sure to read the README.1ST file for detailed instructions on how to apply this fix. The command you use to install the fix is INSTALLF. Use it as follows: - Switch to the A:\OS2FIX subdirectory - Type INSTALLF where: is the source drive and directory, A:\OS2FIX is the drive letter of your OS/2 partition is the drive and subdirectory where you want to store the original modules that INSTALLF will replace. and press the Enter key. If you need assistance, you should call 1-800-992-4777 (the IBM OS/2 Technical Support Line) and indicate you have the fix for APAR numbers PJ09513 and PJ10200 (APAR stands for authorized program analysis report). Inserting your PCMCIA modem with the old versions of COM.SYS and VCOM.SYS will cause OS/2 to trap (stop operation) when your PCMCIA modem is inserted or removed. Some modem/fax applications may not require COM.SYS and VCOM.SYS. In those cases, fixes are not required. Refer to the manual that came with your modem/fax application to determine if COM.SYS and VCOM.SYS are required. However, it is highly recommended that you obtain the fixes to ensure reliable operation. VCOM.SYS and COM.SYS are provided as maintenance fixes for OS/2 and are subject to the terms of the licence agreement for OS/2 version 2.1. If you use the copies of VCOM.SYS and/or COM.SYS provided with this product, you must be a licenced user of OS/2 version 2.1. ====================================================================== 4) PCQUERY Utility - Additional problem determination information Message: Socket X/Y: PCMCIA modem configured at COMx (Address DDDD/IRQ level N). OS/2 will not recognize this modem. See Installation and User's Guide. Explanation: If you inserted your card, and got a high tone followed by a long low tone, it indicates that COM.SYS is present but would not recognize the modem. This means that all four devices that COM.SYS supports are already active, or that the requested IRQ does not match one of the pre-assigned IRQs. If there is no second tone, COM.SYS is not present, or is commented out in your CONFIG.SYS file. Recovery: If COM.SYS is commented out, ensure you have acquired the APAR fix as described in section 3, above,and then uncomment the COM.SYS statement. If COM.SYS is present, but not recognizing the modem, remove one of the serial devices and reboot. Note: There are alternative device drivers to COM.SYS and VCOM.SYS. For example, SIO.SYS and VSIO.SYS, available from The Software Division, can be substituted. These drivers support up to 16 OS/2 serial devices. Some applications such as FaxWorks do not require COM.SYS or VCOM.SYS to be present and can be used under this condition. ---------------------------------------------------------------- Message: Socket X/Y: Card Services function 0x7 failed. Card Services RC=0x11. Explanation: Card Services has determined that there are no available memory regions. Recovery: Make a 4K memory region available. One way of achieving this is to exclude a memory region from EMM386.EXE (if you have EMM386.EXE enabled). ====================================================================== 5) PCRESET Utility - Additional problem determination information Message: Socket X/Y: Could not get exclusive use of PCMCIA modem. Card Services RC=0. Explanation: The configuration software has determined that another application, or applications, has already allocated all available memory mappings for the socket. If the specific socket has the Data/Fax modem plugged into it, the other application is not behaving properly. Recovery: If the other application is started by your AUTOEXEC.BAT or CONFIG.SYS files, you may wish to edit the files to remove the statements that enable that application. You should then power off the computer and restart it. You may also wish to contact the manufacturer of the other application to get a resolution for the problem. ====================================================================== 6) Preventing modem 'unconfiguration' during software resets The configuration software attempts to unconfigure all configured modems when a software reset is performed using . This requires that your machine have a 100% IBM compatible keyboard controller. To stop this from occurring, you can use the /NORESET option. ====================================================================== 7) COMX and supported IRQs If you define COMX as a port, be aware that only the following interrupt request levels are supported: 2, 3, 4, 5, 7, 9, 10, and 15. Note that IRQs 2 and 7 should only be used as a last resort. ====================================================================== 8) Problems with Faxing under Windows 3.1 There are documented problems with faxing at high speeds under Windows 3.1. The limitation has to do with the Window's communications driver COMM.DRV and its handling of 16550 UARTs. Knowing this, many FAX software packages supply a replacement for the COMM.DRV driver which fixes the problem. A replacement for COMM.DRV is supplied with newer versions of Winfax, FaxWorks, and other packages. If you experience difficulty faxing under Windows, we recommend that you find and install a COMM.DRV replacement. Note that the replacement driver that came with older versions of the SystemSoft PCMCIA software, SSCOMM.DRV, did not correct the faxing problem. As an alternative solution to replacing the Windows communications driver, you can edit the SYSTEM.INI file in your Windows directory. By editing the line that begins "COMnFIFO=..." to read "COMnFIFO=0", you can get around the failure mode of the COMM.DRV driver and eliminate faxing failures. Unfortunately, this is not the ideal alternative because it essentially turns off the buffering capability of the modem's UART. This in turn decreases the potential throughput of the modem. ====================================================================== 9) Point enabler support A point enabler is a PCMCIA device driver that does not require Card and Socket Services drivers to be loaded. Point enabler support is only provided for DOS and its advantage is that it saves DOS memory. Prior to Version 1.3, use of the point enabler required that you had a PCMCIA controller on your computer that was compatible with the Intel 82365SL. With Version 1.3, the point enabler support has been expanded to cover some Ricoh PCMCIA controllers as well. This provides point enabler compatibility on the IBM Thinkpad 755, 360, and others. The PCRESET utility is not guarenteed to work on all Intel 82365SL and Ricoh PCMCIA controllers. For hardware that is not compatible with the PCRESET utility, the modem must be inserted at boot time. ====================================================================== 10) WARP support OS/2 Warp has PCMCIA support built into the operating system. For this reason, the drivers supplied on this disk are not required. If you try to install the supplied OS/2 modem driver under Warp, you will be stopped with an error message (Error 9). If you really, want to use the driver on this diskette rather than the built-in OS/2 Warp drivers, please refer to your Warp and PCMCIA modem manuals. You will have to edit your config.sys by hand. The "PCCOM.SYS" driver should be specified below the "BASEDEV=PCMCIA.SYS" statement in the config.sys file. * * * * * * * * * * Acer is a trademark of Acer Inc.
