If you have "real" serial ports - you can use one each of them to both
interface to your radio AND send keying CW.  You can use the parallel port
for the paddle input if you want and it will be directed to the correct

The other option is to build up a small relay box that is controlled from
the one parallel port - and have it switch the CW from the parallel port to
the active radio.
