When you use the US Robotics Sportster V.FC and V.34 modems with any
communications program, the connections may drop unexpectedly.
CAUSE
US Robotics states that the problem occurs due to the incompatibilities in
the V.FC protocols retaining sequences. If your modem has a Supervisor
date of 11/30/94 or earlier, you may experience this problem. To determine
the Supervisor date of the modem, start your communications program and
issue an ATI7 command. The modem's configuration profile appears.
RESOLUTION
To correct this problem, obtain an EPROM chip upgrade and the complete
V.34 28.8-kbps protocol from US Robotics Technical Support at
