Carrier Loss Detection
You want your application to detect loss-of-carrier so that you know
when the connection is complete. You may not be able to put this code in
your controller software, since the controller is running only during the
connect or hang-up process. Once the application detects the loss of carrier,
it can call the modem controller to restore the modem settings.
