I have run into a brick wall on this one...  The Unix PC 7300 has a nifty
routine called 'dial' for accessing the builtin modem that returns a
valid file descriptor for the open line if the call was sucessful.  That
works as advertised (even the the documentation is wrong is several places).

However, I'm having problems disconnecting the line whenever the call
IS NOT sucessful.  If phone does not answer, the 'dial' routine returns
a '-1' as a file descriptor, but the phone continues to ring!

How do you stop the phone from ringing?
