Hi Doug,
I have test the continuity of my cables, they are good.
I have tried with LPT1 in willem software.
So I will give you more info when I will test with a XP with built in parallel port.
When i connect willem to lpt i get red power light come up, when i connect power to willem (usb or dc 12V) i got two other lights come up (green) and then i run software which runs ok without errors (green lights turns off when i start the program) port setting is LPT1:0x387, version 0.97ja
