RAS Auto Answer Fails with GVC FM144v Modem

ID: Q131867

The information in this article applies to:

Microsoft Windows NT Workstation version 3.5
Microsoft Windows NT Server version 3.5

SYMPTOMS

When you use the Remote Access Service (RAS) Admin with the GVC FM144v modem (also known as the F-1114 V/R6), RAS fails to set the modem to auto- answer mode properly. This results in the GVC modem not responding to an incoming call, or not handshaking even if it does pick up the call.

CAUSE

The MODEM.INF file specifies the following initialization string:


   [GVC FM14400]
   COMMAND_INIT=AT&F&C1&D2Q0V1E1S0=0S2=128 S7=55 S95=44<cr>

The S95=44 command causes this problem. This command enables a set of result messages for the event sequence when establishing an error- controlled connection. It does not affect the way the modem negotiates a connection; it only enables the message options.

NOTE: The "R6" in F-1114 V/R6 is a revision number for this modem. This revision does not support the S95 register.

RESOLUTION

Remove the S95=44 text from the [GVC FM14400] section of the MODEM.INF file (located in the %SYSTEMROOT%\SYSTEM32\RAS directory).
