SYMPTOMS
When you try to connect to a version 3.x of Microsoft Mail for PC Networks Mail Transfer Agent (MTA) with Microsoft Mail Remote for Windows (or MS-DOS) using a U.S. Robotics Sportster 28.8 V.34 modem, the MTA may never answer. Therefore, it causes the Remote user to time out.



CAUSE
U.S. Robotics Sportster 28.8 V.34 modems with a "Supervisor date" earlier than 04/18/95 have a ROM BIOS chip defect.



RESOLUTION
This is a known issue with U.S. Robotics. Please contact U.S. Robotics Technical Support at (708) 982-5151 for information on upgrading the modem.



MORE INFORMATION
To determine if the modem has the suspected bios problem, connect a session to the modem port from Terminal.

Once connected, type the following (followed by a carriage return):
