READ.ME file for the IBM Infrared Wireless LAN Adapter ========================================================================== CONTENTS: 1) Supported computers and Card and Socket Services 2) Using IBM TCP/IP for DOS with the Infrared Wireless LAN Adapter 3) Access Point configuration notes 4) LAN Support Program installation notes 5) Lantastic installation notes 6) Windows for Workgroups configuration notes 7) Starting the IRUTILS.EXE Program ========================================================================== 1) Supported computers and Card and Socket Services The Infrared Wireless LAN Adapter is fully compliant with the Card and Socket Services Standard, versions 2.0 and 2.1. It should therefore work with any Card and Socket Services that are also fully compliant with the 2.0 or 2.1 Standards. The following table illustrates those computer and Card and Socket Services configurations that have been tested and are known to work properly. Note that while the adapter will work on each computer without the presence of Card and Socket Services, this configuration is not recommended. The following Card and Socket Services are represented in the table: - IBM DOS Card Services - Phoenix PCMPlus - Award CardWare with Award PC ENABLE - SystemSoft CardSoft with SystemSoft Card Services Allocation Utility Machine/ | NO IBM Phoenix Award SystemSoft Card | C&SS C&SS PCMPlus CardWare CardSoft --------------|------------------------------------------------ Acer V386SL | OK OK OK --------------|------------------------------------------------ AST PowerExec | OK OK --------------|------------------------------------------------ Data General | OK OK OK --------------|------------------------------------------------ IBM TP 500 | OK OK OK OK --------------|------------------------------------------------ IBM TP 710T | OK OK OK OK --------------|------------------------------------------------ IBM TP 720 | OK OK* OK* OK* OK* --------------|------------------------------------------------ IBM TP 750 | OK OK OK OK OK --------------|------------------------------------------------ Intel ExCA | OK OK OK OK OK --------------|------------------------------------------------ NCR 3170 | OK OK --------------|------------------------------------------------ NEC Ultralite | OK OK OK OK --------------|------------------------------------------------ PS/Note | OK OK OK OK --------------|------------------------------------------------ Toshiba T4500 | OK OK OK OK OK --------------|------------------------------------------------ Zenith 425L | OK OK OK --------------------------------------------------------------- * The Micro Channel version of Socket Services is required for this machine. ========================================================================== 2) Using IBM TCP/IP for DOS with the Infrared Wireless LAN Adapter For users running IBM TCP/IP for DOS V2.1.1 we recommend obtaining the corrective service diskette (CSD) for program temporary fix (PTF) UB10718 to upgrade to V2.1.1.2. This upgrade will improve your performance and reliability when running IBM TCP/IP for DOS over the IBM Infrared Wireless LAN Adapter. This and future CSDs for this product may be obtained electronically from the following sources; i) With anonymous FTP from SOFTWARE.WATSON.IBM.COM Look in the pub\tcpip\dos directory ii) From the NCSBBS bulletin board at 1-919-517-0001 Set your modem settings to: none,8,1 ========================================================================== 3) Access Point configuration notes 3.1) Ethernet Access Point Performance of the access point is affected by the amount of Ethernet network traffic that it must examine. A faster PC or a faster Ethernet adapter may be required in situations where the Ethernet network traffic is heavy, or computationally intensive applications run in the foreground. 3.2) Token-Ring Access Point The performance of the Token-Ring access point is also affected by the amount of Token-Ring traffic that it must examine. However, the Token-Ring access point only has to examine a very small number frames from the Token-Ring. The performance of the Token_Ring access point will mostly be affected by computationally intensive applications running in the foreground. 3.3) Running Protocol Stacks on IR Mobiles This section contains tips on configuring various protocol stacks to operate on the IR mobiles. Note that the Token-Ring access point software expects the IR mobiles to use the 802.3 frame format regardless of the protocol stack being used. Be sure to configure all protocols to use 802.3 frames (sometimes referred to as IEEE frames). Some protocol stacks, e.g. PC3270 for DOS, will also require you to install 802.2 protocol drivers (e.g DXME0MOD.SYS from LSP) if they are not part of the program package. Conversely, other protocol stacks, e.g. DOS TCP/IP, bundle their own 802.2 drivers. Be sure to read the documentation supplied with the communication package you will be installing on the mobile PCs. TCPIP ----- Be sure to specify the 802.3 frame type during installation. Set the MTU size to 1492 or smaller. For IBM TCP for OS/2, this is done through the TCP Configuration icon. For IBM TCP for DOS, you will need to change the MTU parameter in the \tcpdos\etc\tcpdos.ini file and the \tcpdos\bin\tcpstart.bat file to 1492. SNA/NETBIOS ----------- There is no special set up required for these protocols othr than the regular configuration for Ethernet based nodes. Novell ------ If you plan to use the Novell protocol stack, be sure to include the following line to the TR_MGR.INI file for all Token-Ring access points: NOVELL = 01 Lantastic --------- Configure the Lantastic nodes to use IEEE frames. Be sure to install 802.2 (LSP) drivers and enable IPX routing. Windows for Workgroups (WFWG) ----------------------------- Be aware that WFWG nodes can not communicate with each other across a Token-Ring to Token-Ring bridge. ========================================================================== 4) LAN Support Program installation notes In the LAN Support Program installation section of the Infrared Wireless LAN Adapter Installation and User's Guide, you are instructed to accept the default settings in the Environment Information panel. Please be aware that the default settings for this panel may differ, depending on the version of the LAN Support Program you are installing. ========================================================================== 5) Lantastic installation notes Please note that the installation guidelines provided in the Infrared Wireless LAN Adapter Installation and User's Guide cover the installation procedure for Lantastic V5.0. If you are installing Lantastic V6.0 please refer to the Artisoft documentation included in the Lantastic package. ========================================================================== 6) Windows for Workgroups configuration notes To obtain the maximum performance and reliability in Windows for Workgroups using the IBM Infrared Wireless LAN Adapter, we recommend you make the following configuration changes: 1) CONFIG.SYS file - Add the following lines or modify existing ones. FILES=128 FCBS=25 2) PROTOCOL.INI file (which is in the Windows directory) - In the [NETBEUI] section increase the values of SESSIONS and NCBS parameters: SESSIONS=20 NCBS=40 3) SYSTEM.INI file (which is in the Windows directory) - Add the following lines or modify existing ones in the [386Enh] section: NetHeapSize=64 TimerCriticalSection=6000 EMMExclude=xxxx-yyyy (Where xxxx-yyy is the shared RAM space for the adapter) NumHCBs=64 Add the following line or modify the existing one in the [Network] section: MaintainServerList=Yes Also, if after making the above modifications you are experiencing any reliability problems running Windows for Workgroups over the IBM Infrared Wireless LAN Adapter, we suggest you obtain the latest version of the following two files from Microsoft: a) VNETBIOS.386 b) NDIS2SUP.386 These files can be obtained through the Microsoft Software Library, either on CompuServe or via FTP at ftp.microsoft.com. a) VNETBIOS.386 - stored as WG0970.EXE in the Microsoft Software Library Run WG0970.EXE, a self-extracting archive, to obtain VNETBIOS.386 Copy VNETBIOS.386 into the "system" subdirectory of your Windows directory In the SYSTEM.INI file (in your Windows directory) change the Network= entry as follows: change Network=*vnetbios,*vwc,vnetsup.386,vredir.386,vserver.386 to Network=vnetbios.386,*vwc,vnetsup.386,vredir.386,vserver.386 b) NDIS2SUP.386 - stored as WG0971.EXE in the Microsoft Software Library Run WG0971.EXE, a self-extracting archive, to obtain NDIS2SUP.386 Copy NDIS2SUP.386 into the "system" subdirectory of your Windows directory ========================================================================== 7) Starting the IRUTILS.EXE Program When starting the IRUTILS.EXE program, one of the following messages may be printed on the screen: "E:0001" This error message means that there is not enough memory free to run the IRUTILS.EXE program. It needs at least 390K of conventional RAM free. Press any key to return to DOS. "E:0002" This error message means that a critical file needed for the operation of the IRUTILS.EXE program is missing. Press any key to return to DOS. "W:0003" This warning message means that files necessary for the installation of the Access Point software are missing. The installation option will not be present.
