APPLIES TO

This article was previously published under Q119623

## SYMPTOMS

When you are using Workgroup Connections version 1.0 and Remote Access Service (RAS) version 1.1a, a modem connection using compression to a Sprintet X.25 Packet Assembly/Disassembly (PAD) may fail and the following error message may appear:
RAS Error 212
Bad Modem or COM Port Failure

## CAUSE

After renaming MCOMP.INF to MODEM.INF and dialing to the X.25 PAD, the connection drops upon PAD initialization and results in the error message above.

## WORKAROUND

To avoid this problem, use the MODEM.INF file that comes with RAS 1.1a and limit the modem transfer rate to 9600 baud.
