No, it is a straight pass through... the unit itself is plugged into the
port, it is quite small. It has an audio lead to my sound card's line in,
and an antenna.

No, he was not pleased that I asked, even after I offered to send him all
of the source, binaries etc for a DOS version....

I have tried the first idea, with a terminal, but I need to try the
