Do the inputs work?
The most likely thing is that you don't have the right base address.

The script sets the port to 0x378, but there are still computers that use 0x278, or you could even be testing a PCI card port, not enough info to tell.
Why are you testing the port, is it because your machine does not work, or is it because you don't have a machine yet and are just testing out of curiousity?
regards

See last post here:
forum.linuxcnc.org/18-computer/4743-para...port-tester?start=10
I have the same problem.
The port tester give all signals on the display.
But LinuxCNC receive nothing.
It is a DELL Optiplex GX620. Now i order a SHINESTAR PCI to DB25 LPT Parallel Port Expansion Card with Low Profile Bracket
and hope, this will work.

use
dmesg | grep parp*
to detect the correct parport adress
it seams to be the wrong one
then use HALshow
in mashine menue
(watch List( select
parport.0 pins to be watcht

That means they are not connected to anything in HAL.
Use the show pin in hal watch and check the names of the hal pins that the limits are attached to.

Address 0x378.
What's the address 0x778 ?
HAL show Pin 10-13 no action.

can you tell how the Switches are connected
GND 5V BOB -> Switch -> Limit_in
this is the Correct Wirering

I connect switch 1 (NC) to GND and Limit port 1.
Switch 2 GND and Limit port 2.
And so on.

There are so many Fake and dummy Boards out
THE Blue Ones
I Hope You dident catch a Fake one with no Inputs working at all
AS You did the Wirering right and you got no signal
PLEASE Check im COM from the AXIS are the SAME as COM from the Limit
