Software not talking to hardware. New build

You actually don't know if the software is talking to the hardware or not until you can verify that you can/cannot change parallel output bits or read input bits via LinuxCNC

That's why I asked if you can see the direction signal change on the parallel port
when you jog in either direction. This will with one test eliminate all parallel port addressing and driver questions.

Makes it really hard to keep track.

I advised the OP against this.

How do I do that?

One way is to check if the parallel port pin that's used for direction
changes state (output voltage) when you jog in opposite directions.

You can either use a voltmeter or a LED with a resistor to test an output.

The positive of the voltmeter or LED to the output you want to test and the negative to the ground pin of the parallel port. You will need to use google to find a picture of a parallel port showing the signals. Ground is pins 18 - 25.

So I unplug the b.o.b. and test the parallel port pin with volt meter?
I must say when I start my machine all the steppers lock up
