The information in this article applies to:

  • Microsoft Windows NT Server 3.1
  • Microsoft Windows NT Workstation 3.1
  • Microsoft Windows NT Advanced Server 3.1
  • Microsoft Windows for Workgroups 3.11

This article was previously published under Q117585

SYMPTOMS

If you attempt to use your Supra Fax Modem V.32bis 144i to run Windows NT or Windows for Workgroups remote access services (RAS), the modem fails to initialize.

CAUSE

This happens because the RAS MODEM.INF file contains commands that are not compatible with the Supra Fax Modem V32bis 144i.

RESOLUTION

To get your modem to work with RAS, use the following procedure:

  1. Open the MODEM.INF file in the SYSTEM32\RAS sub-directory in a text editor such as Notepad.
  2. In the [Supra Fax Modem V32bis] and [Supra Fax Modem V32] sections of the MODEM.INF file, make the following changes:

    1. Change "<protocol_on>=\\N3" to "<protocol_on>=\\N".
    2. Change "<compression_on>=%C1" and "<compression_off>=%C0" to "<compression_on>=%E" and "<compression_off>=%E1".
    3. If you are using auto-answer mode, change "COMMAND_INIT=AT&F2&C1&D2 S7=55 <cr>" to "COMMAND_INIT=AT&F2&C1&D0 S7=55 <cr>".

      NOTE: If you are using Windows for Workgroups RAS, after this step, the modem may not relenquish control of the telephone line after disconnecting the remote server. (This may be a problem when the modem is used on a line that is also used for voice.)
