I am doing some serial port interfacing. I want to create a function that
will scan all com ports 1 - 9 and look for specfic devices. Once the port
with a modem has been detected I am going to dial out using standard AT command
strings to another modem and transfer information.

The connecting and using AT strings is not the problem. I would like to
know if anyone can point me in the direction to look for a great sub or function
that will probe the serial ports looking for the modem (since every machine
has one on a different port).

Thank you in advance for any help. Its greatly appreciated.
