This is what I used for quite a while. It is adapted from many other
designs out there.

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
radio.
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.

For the 10 years that I have used TR Log, I have always keyed my 2 radios
using parallel ports. I have now changed to another computer which only
has 1 parallel port. It also has 2 serial ports for controlling my two
rigs plus a couple of USB ports. Can I key one of my radios with a serial
port or from a USB port to a serial port adapter cable? Any help or
suggestions would be appreciated.
