I built a breakout jig using a straight through breakout board so I could check the signals right out of the pc port. I am checking signals there and at the drive terminals. I built this pc and a printer driver has never been installed. It uses a asus motherboard. Sometime back I had another pc that also had a asus motherboard (different versiion) and could not get it to work. Thats when I decided to fix some things mechanicaly on my machine. I have that done and am back to trying to make it run again. Think I will call it a day and get a fresh start tomorrow. Thanks for all your help. I will post progress tomorrow.

I have done everything I know to do. I have two computers with Asus boards (P5GD1-VM and P5PE-VM). Neither one of them will work. I have tried everything I know to do. I even added a second parallel port and nothing works. 

Have you disconnected the cable and put your meter directly to the parallel port?
If you have and its not correct please attach your xml and I will see if there is an issue in it.

Yes. The jig I built lets me read the voltage at the end of the cable. I have also tried a different cable.

can you attach the xml please.
Hood

yes

Everything looks fine in the xml so assuming you have the port address correct I am afraid I dont know what to suggest. Personally I would still check directly at the port, I know you said you tried two cables but there is a slim chance they could both be bad.

Does your motherboard have onboard graphics? Sometimes that can upset things but it is usually a bad pulse rather than bad voltages. Also might be worth trying the optimisation steps detailed on the downloads page if you have not already done it.
Hood

Yes it does.

Your xml worked here with version .033.
I would try uninstalling your PP and reinstalling it. I have an Asus motherbord in my new PC and works supper.
The motherboard didn't have a PP and I used a card. Does the board ou built board show that the PP pins are working?

....OH, BTW I changed your configuration  such that the Estop was emulated.......
So try that first!
