You no longer have a parallel port? Your computer can't run WinPLC anymore? Maybe it is time to start considering to use the K8055 card instead. It is an interface card by Velleman, which uses USB as connection to your PC. It basically runs on all Windows computers.
I have started to develop a program which will help you to control this K8055 card. The program is still in development, but you can already find some information about it. You can even download a demo version.
