SUMMARY
This article describes the availability of Microsoft's 32-bit Data Link Control (MSDLC32) protocol and provides information regarding Microsoft support policies for this protocol.



MSDLC32 Explanation and Availability
MSDLC32 is a 32-bit networking protocol for Windows 95. Its primary use is by 3270 emulators for connectivity to IBM mini/mainframe computers. In many implementations, it replaces the 16-bit MSDLC that is currently available. The benefits of MSDLC32 are improved performance and an increase of available conventional memory. A configuration reporting and logging utility, Trcdlc.exe, is included. To download the Msdlc32.exe file, please see the &quot;Instructions for Downloading&quot; section later in this article.

MSDLC32 Support Information
Microsoft Product Support Services supports the following: installation of this protocol through the user interface; functionality of the configuration dialog boxes; and booting without error with the protocol installed. Desktop Systems supports the command-line syntax of the Trcdlc utility. For more information about the command-line parameters for Trcdlc.exe, please consult the Readme.doc provided with the add-on.

Microsoft will not support issues related to connecting to another computer with this protocol. For more information about server-related settings or other information regarding setting requirements to connect to the server with MSDLC32, please contact your System Administrator or the manufacturer of the network software.
