When a client disconnects from a RAS server, the DTR line on the Digiboard
COM port may not return. Because the modem is not reset, no additional
calls can come in on that port. If a client attempts to dial in, the modem
picks up the line, but the RAS server does not respond. As a result, the
client receive a 640 error message. The RAS server does not log any errors
in the event log, but the RAS Administrators tool show that the port has
been disconnected and is not ready.
These symptoms will appear only after the RAS server has been in operation
for some time. Stress tests indicate that several hundred inbound calls are
needed to produce the problem.
