That is weird indeed, do you have a screenshot of the device manager showing it? Its not that I am not believing you, just I may see something.

This is after I uninstalled the port in device manager, turned off the computer (not a restart), turned o the computer, went into the root menu/integrated devices/parallel port and went through the options of   'off,at,ps/2/epp,ecp' stopped at EPP and saved changes and exited.   When windows opened, I tried to open add hardware under control panel, but it said I had to wait as it was already installing hardware.   Low and behold, the hardware it was installing was the ECP port.......again.  So, I again tried to scan for hardware changes and got nothing.

On a side note though....While in the bios I saw that under the option of ecp port, it asks if I would like the DMA channel on or off??

Is that of any significance?

DMA is direct memory access, cant recall ever seeing that in the BIOS associated with the parallel port but suppose I have just missed it. I would try with it in both states, more likely to be disabled though.

STill no change.  I rechecked pins at the back.  It is still apparent aht 12 & 13 don't work on this computer.  15,13, & 11 are good.  At this point, I'll try to reconfigure with that until I can get a pci card for this pc.  (it's one of those little desktop Dells that has a different length of slot cover due to it's small size).  I'm going to change my configure to x--=11, y--=15 and all others run series to 10.  I'll share 11&15 as homes for x & y.  The rest can be set as soft limits, right?  

What, exactly, is the method of checking the direction and pulse pins?

Edit:  I will search for that as I'm sure it's been covered.

ReEdit: Hood, just so happens you're the one answering the question there too.  LOL

I've been meaning to ask if you ever sleep....

Next step if that is successful.........hooking up to the control box.

Both of you guys have been a great help.

Thanks,
Rooney

Yes,

Pins 12 & 13 would do nothing no matter active high or active low configured.

Yes.  Under the diagnostic tab in Mach the LED does change off and on when I short to ground.  All except 12 and 13.   Wchich doesn't change configured as active high or as active low.

Ah OK then the port has to be bad as that means Mach is seeing the correct port.
