RAS Error 652 Using MultiTech MT2834 Modem

 Last reviewed: September 9, 1996
Article ID: Q129426
The information in this article applies to:
  • Microsoft Windows for Workgroups version 3.11

SYMPTOMS

One of the following error messages appears when you use a MultiTech MT2834 modem with the Windows for Workgroups 3.11 Remote Access Service (RAS) software: 

   Error 652 Unrecognized Text Response: <h86><h9E>]<h86>

   -or-

   Error 652 Unrecognized Text Response: <h1C><h00><h00><h00><h00>...
NOTE: You may see a different response string other than the two noted above.

This error message appears if you have enabled callback for the account used to dial-in to the RAS server. If you connect to the RAS server without callback enabled, no error messages appear.

Increasing the CALLBACKTIME parameter in MODEM.INF does not solve the problem.

WORKAROUND

To work around this problem, do not enable callback for your RAS account if you are using a MultiTech MT2834 modem. If you need to have callback enabled, use a different modem, or use Windows NT 3.5 RAS as your RAS client software.
