Terminal emulation applications offer several different connectivity options for connecting to a host IBM AS/400, or DEC VAX computer. This section describes configuration and other issues related to using terminal emulation programs.
Connecting to a NetWare for SAA gateway.
For most emulation applications, configuring Windows 95 with the Microsoft IPX/SPX-compatible protocol enables connectivity to a NetWare for SAA gateway or to any gateway supporting IPX/SPX connectivity. If you are using a token-ring network with source routing, use the Network option in Control Panel to make sure that Microsoft IPX/SPX-compatible protocol appears in the list of network components. In Advanced properties for the protocol, set the Source Routing property to a 16-entry cache size.
If this configuration does not work well, configure Windows 95 to use a Novell-supplied real-mode NetWare client.
Connecting to a Windows NT SNA 2.0 or 2.1 server.
Windows 3.x client software supports connectivity to a Windows NT SNA 2.0 or 2.1 server. The Windows NT 32-bit client for SNA should not be used; it was designed to work only with client computers running Windows NT Workstation.
Connecting to an AS/400 with IBM PC Support software.
You can use Windows 95 to connect to an AS/400 using the IBM PC Support software. To do so, configure the PC Support application for Basic Mode; do not use Extended Mode. If the PC Support application was configured to connect using DLC, make sure that Microsoft DLC or IBM LanSupport is already installed on the computer.
You can also use Windows 95 to connect to an AS/400 using the NetWare for SAA gateway and the IBM PC Support application. Configure the PC Support application for Basic Mode; do not use Extended Mode. The IBM-supplied DOS16M.386 file is not compatible with Windows 95.
If Windows 95 is configured to use the IPX/SPX-compatible protocol, then you must create a WINSTART.BAT batch file in the Windows directory and add entries in this file to run PCSWIN.COM and STRNRTR.EXE (the Novell-compatible router). If you encounter problems using the protected-mode IPX/SPX-compatible transport with the Novell-compatible PC Support router, then configure Windows 95 to use the Novell-supplied NETX or VLM client with IPXODI, as described in Chapter 9, "Windows 95 on NetWare Networks."
Connecting to host computer using a coaxial adapter.
If you are using a coaxial connection with a coaxial adapter (CUT/DFT) supplied by IBM or another vendor, use the real-mode drivers provided with the adapter or emulation software for setting up hardware. No 32-bit drivers are available for connectivity with this type of adapter.
