MS DLC Fails to Respond to TEST Frames.

ID: Q119399

The information in this article applies to:

Microsoft LAN Manager, version 2.2

SYMPTOMS

Applications fail if they are based on the real mode Microsoft Data Link Control (MSDLC) stack and use TEST frames to initiate a connection.

CAUSE

As the default, MSDLC does not pre-allocate SAP transmit buffers, and does not respond to TEST frames sent to any SAP except SAP 0 (Global SAP, reserved).

RESOLUTION

Make this entry to force MSDLC to pre-allocate transmit buffers on SAPs:


    PROTOCOL.INI
   [msdlc_xif]
        trxbuffers = x

where x is the number of buffers to allocate, typically 2.
