UpDate, 

The Machine is up and running.  Found a youtube video with the correct settings for my machine.  The one page set up that came with the machine was close but no ringer.  Scrapped my modified PC, picked up an XP 32 Bit PC with a parallel port entered the new settings and Bingo.  Thanks for all the input, everyone has been helpful.

Mach is running fine, Port 2 is my Db25 card and has no driver issues and is suppoted by EPP mode.  Think I might scrap my comp and get a fresh comp running XP with a Db25 port built into the mother board which would give me LPT 1 for my default port.

I've tested my drivers, drivers are good,  my port settings are set to port 2 and my I/O is 800. Port 1 has been disabled and port 2 is enabled.  My Mach3 program is fine, pins 1-13 have 5v so I'm getting current out of my Db25 port in the back of my comp.

I'm isolating my pins by inserting a paper clip into the individual pin holes on the Db25port in the back of my comp.   My card is fine my drivers checkout.  I have a BOB and power source isolated inside a metal CNC control box.  Since I'm not even hooked up to the BOB none of that is an issue.  I can't get any reading off any pins .  I have 5v on pins 1-13 but can not get a change on any of them when testing my X Dir Pin.  I've tried setting each pin to my X Dir Pin setting.  None have given me any change in voltage.  I understand my step pins won't give me any readings because I'm not using an oscilloscope but my Dir pins should have a voltage reading and show a 00v reading when pressing the - arrow to that axis.  I'm working with  Mach support to see what I can try.

As I understand you need an oscilloscope to check the step pins but the Direction pins should give you a 5v - 00v reading when pressing + and - axis keys for that pin.  I don't have an oscilloscope to check my step pins but I'll try and borrow one for further testing.  I taught electrical theory before I retired but don't have access to the school anymore.
When I said cut, I meant the Mach3 program goes through the entire process of running the g-code.  I get nothing from my CNC Machine.  I understand vocabulary is critical here.  Sorry for any confusion.  I set all my pins to 0 and started with my X Dir Pin.  I set it at 2 and moved my X Axis DRO by pressing my left and right Arrow keys, Then 3 and 4 and so on testing my X Dir Pin setting one digit at a time and still have no movement on my CNC table.  Mach3 isn't giving me any errors my computer has been ran through all my drives and my CPU and all is working fine.

Port 1 is disabled Port 2 is selected and the correct three digit number (800) has been set. I've put the question to Mach support and I'm waiting for a reply.

My card is on port 2  800  My port 1 378 isn't a 21 Pin Port.  My Mach 3 is running fine.  Cuts the Road runner and Ball templates just fine.  Arrows and Pge Up Pge Dwn move my XYZ Axis settings just fine.  I'm not sure where I loose my signails but they aren't getting to my Step motors and from my volt tests my port isn't putting out any signals.  I installed an ASIX MCS 9835 parallel card and it has installed just fine my Mach3 program runs through G-Code just fine.

I'm not getting any change in my pin voltage under any circumstances.  I use my Port 1 378 Port 2 800 and nothing.  Port 1 378 nothing and Port 1 800 gives me an error.  So i'm thinking it may be the 21 pin card I installed on my computer.  Any suggestions on what card to use??

Thanks Wayne

From what I have read and viewed on the tutorials  there should be a 00-5v difference in a pin when the + and -  arrows are pressed.  for example pin 2 and 3 are the X Axis pins.  when pressing  the +X arrow testing  pin 2 you should read 5v.  When you push the -X arrow pin 2 should now read 00.  I have a constant 5V.

Thanks for your reply,  I have read the manualseveral times and that is why I think something is not right but not sure what.  The download went well my test run with the Road Runner
G-Code went well.  When I test my arrow keys my axis move in the program.  However I'm not getting movement on my stepper motors.  So I tested my port pins in the back of my computer.  As I said my entire top row 1-13 are hot with 5V my bottom pins are 25-16 are 00 and pins 17-14 are 5V (I had the bottom row info reversed in my first post.)
So see if I understood,  pins 1-9 are output, pins 2-7 are XYZ outputs these should only have voltage when the corresponding arrows are pressed.  Pins 10-13 are input, The input should read 00 since there are no signals being sent from the cnc board back to the computer.  My 10 pin is my E-Stop.  Pins 25-18 are common and should read 00. 17-16 are output 15 input and 14 output.  Am I correct ??
