Running 16-bit 3270/FMI Applications on Windows NT & Windows 95

• Microsoft SNA Server, versions 2.1, 2.11, 2.11 SP1, 3.0
  on the following platforms: NT

SUMMARY

For Microsoft Windows NT computers, the SNA Server's Windows NT client software ships with "thunking" DLLs to support 16-bit Windows APPC, CPIC, LUA, and Common Service Verb applications, on top of the 32-bit Windows APPC, CPIC, LUA, and Common Service Verb DLLs. However, these thunking DLLs do not support 16-bit Windows 3270 Emulator Interface Specification (EIS, also referred to as "FMI") applications.

The SNA Server Windows 95 client software does not support thunking for any of the 16-bit SNA APIs. Only 32-bit Windows APPC, CPIC, LUA, Common Service Verb, and 3270 EIS application are supported on top of the SNA Server Windows 95 client software.

To run 16-bit 3270 EIS applications on the Windows NT where SNA Server is installed, see the special instructions below for installing the SNA Server Windows 3.x client software on Windows NT, concurrently with the SNA Server Windows NT client software.

To run 16-bit 3270 EIS applications (or 16-bit APPC, CPIC, LUA, CSV applications) on the SNA Server Windows 95 client, the SNA Server Windows 3.x client software must be installed. However, Microsoft does not support installation of the Windows 3.x client if the SNA Server Windows 95 client software is installed.

MORE INFORMATION

The following describes how to install the SNA Server Win3x client-server interface in various environments in order to get 16-bit 3270/FMI applications working:

On a Windows NT computer where the SNA Server is actually running

1. Start the SNA Server Win3x client Setup program on the SNA Server.



2. In the Client/Server Protocols dialog box, select the TCP/IP option.



3. In the SNA Server Location dialog box, select the Remote option Enter the IP address or computer name of the SNA Server that the Win3x client is being installed on. In other words, the remote destination is pointing to itself.
   
   With this configuration, both 32-bit and 16-bit 3270/FMI applications work on the same computer.

On Windows NT computer that you intend to be running an SNA Server client

On a Windows 95 computer

On a Windows 3.1, or Windows for Workgroups computer
