Here is what my registry shows:

You will notice that Parallel Port 1 shows ... ,78,03, ...
This could be interpreted as 0378

And the same is true for the serial ports. So, there is a way to decipher this, but it would take time. There has to be an easier way. If all else fails, looking for VB code that can do it and translate it into VFP code.
