SUMMARY

TBMI2.COM is a memory resident utility provided by Novell for distribution on the Microsoft Windows operating system version 3.1 distribution disks. The Task Buffer Management Interface (TBMI) is a file meant to be used in standard mode Windows when the NetWare IPX and SPX functions are loaded. The purpose of the file is to prevent a task switch in Windows from breaking the communication between IPX and the various software processes associated with a particular application.

In more technical terms, TBMI2.COM acts as a buffer and manager between the IPX and a calling process. If an application process calls IPX and then the task switcher is invoked, then IPX could send its response to the wrong process. TBMI2.COM prevents this from happening.

MORE INFORMATION

The NETWORKS.WRI file states the following: 

   TBMI2 enables you to safely run applications that use
   IPX and SPX functions in standard mode Windows or the
   MS-DOS 5.0 task switcher.
NETWORKS.WRI also explains that Novell suggests loading the file at bootup time with a batch file. NETWORK.WRI offers no further clarification of the functionality of TBMI2.COM.
