James:

Thanks for the clarification.

The reaosn I suggested SERIAL and not USB is because I know that some
USB modems work, some don't, and I personally have/had no idea how 
to tell without first buying it. So, to avoid giving the OP a bum
steer I suggested what should be foolproof (assuming you can find a
serial modem in the stores these days).
