RAS Server Resets in Answer Mode with Sportster Modem

ID: Q116158

The information in this article applies to:
  • Microsoft Windows for Workgroups version 3.11
Microsoft does not encourage nor support user changes to .INF files; therefore, Microsoft Product Support Services (PSS) does not support the procedure in this article. Although we have tested the following procedure and it appears to function as described; we strongly recommend that you make a backup copy of your .INF file before you proceed.

SYMPTOMS

When Remote Access Services (RAS) is placed in answer mode with a U.S. Robotics 14400 Internal Sportster modem, the modem may stay in a continuous loop between "Waiting for Call" and "Device Reset." This issue occurs only when the device is placed in answer mode with the RAS point-to-point server.


RESOLUTION

To correct this problem, edit the modem initialization entry (COMMAND_INIT=) in the [US Robotics Sportster 14400] or [US Robotics Courier V.32bis] section of the MODEM.INF file as follows:

  1. Run Microsoft Windows for Workgroups Write and open the MODEM.INF file.


  2. Choose the No Conversion button.


  3. From the Find menu, choose Find.


  4. In the Find What box, type [US Robotics Sportster 14400] or [US Robotics Courier V.32bis] and then choose Find Next.


  5. Choose Cancel and then change AT&F to ATZ&F. For example, change
    COMMAND_INIT=AT&F&C1&D2 V1 S0=0 S2=128 S7=55 W1 S95=44
    to:
    COMMAND_INIT=ATZ&F&C1&D2 X7 V1 S0=0 S2=128 S7=55 W1 S95=44


  6. Save the MODEM.INF file.


  7. Quit and restart RAS Phonebook.

    This issues a reset command that resets the modem to the factory defaults.


The X command setting establishes compatibility with older modems that send different result codes to the receiving modem. X7 is used to enable result codes 0-11 and 13-43, which are used mainly on U.S. Robotics modems. Check the BIOS date of the modem and then check with the modem manufacturer to determine the current modem BIOS date available.
