SYMPTOMS
A modem that the Remote Access Service (RAS) server uses does not answer incoming calls.



CAUSE
The RAS server sends initialization commands to the modem with no delay between commands. However, because some modems cannot process commands when no delay occurs between commands, some modems do not initialize. Therefore, the modem does not answer the incoming call.
