help would be greatly appreciated.

The general problem is going to be that WINXP, 2000, Vista, and NT make
it difficult to use the printer port pins directly. Not impossible, but
certainly a problem.

You could use something like a PIC877 or some such to act as a serial
input which would then allow using Rs232 to communicate from the PC to a
radio.

Alternatively, use WIN98 and the printer pins are "up for grabs" with
fairly simple PC programs.
