Yes tweakie I cannot make any sense of the voltages either and I am sure the pin allocation is correct. Incidentally pin 1 gave 4.1v, the highest reading on the port.
I think it is time to take the lid off and have a look. Oddly my spare XP machine gives similar readings; any chance of the port driver being corrupt.
I have now got a copy of W2000 and may try that on my spare M/c.
I am attaching my xml as requested.

Tweakie, thanks for you sticking with me. I will post my xml file tomorrow when I go into the shop. I have changed the pin settings so often I cannot remember where I started.
Today I checked the P/port output pin voltages  again while pressing the axis direction keys on the jogging 'fly-out'.

Pin 2 - Pressing X- gave 2.37v,    X+ gave 3.32v
Pin 4 -   "          Y-    "   3.07v     Y+    "   3.32v
Pin 6 -    "         Z-    "   3.06v     Z+    "   3.32v
These readings reversed if motor output set to Dir low Inactive but the voltages remained the same.
Two things strike me; very little change in the voltages and how did it work before under W2000.
Could I have an electrical problem on the mother board. By the way at start-up it states the driver is initialised.

Found time to look at the jog button and I try my jogging tests with it active.
That does not appear to be the problem or the solution.
I find I can jog in one direction with each axis, say X+,Y+ Z+ using the buttons on the MPG Mode 'fly out'.
The minus direction buttons produce no movement. These two states can be reversed by checking active low, but no how can I get any
axis to drive + and - using the buttons.
I feel sure it is a port and pins problem but what needs altering or should work with the X,Y,Z axis's.

I have not touched the jog button. Will check this tomorrow.
Thanks tweakie

 Tweakie,
First thing to say is I changed my CNC computer for a spare I have which was also running XP. No difference in control so I conclude the problem lies elsewhere.
Using your figures/instructions I set up the spindle pins which had not been my priority earlier. Obtained immediate control of the spindle speed and direction, great!!.
 Noted that spindle speed does need setting up. Secondly no speed displayed in the DRO. Played about for s few minutes then Crash?? spindle stopped dead.
Opening up the covers revealed that the index plate had come loose and working up the shaft had jammed the shaft. Re-secured it but every thing dead, further examination
revealed a blown 5amp fuse. Replaced, and we had lift off with the spindle.
However neither X,Y, nor Z axis would move at all, not even in a singe direction as I had yesterday. Another blown fuse??. There is power to the driver control box, (red light ON).
Where from here??

I have read the section on attachments but find one area has not been considered.
After three attempts to send some files I have failed but now unsure what to do.
First error ' an unacceptable extension'
Correct the extension and send again. Error 'file of that name as already been sent, rename files'
Did this and now the error is ' this message as already been sent'.
Problem is you cannot see what has been accepted or what is causing the error nor how to restart.

What is my problem and how do I overcome it.
