PC GPIO pins

Good afternoon I'm using Venoen P12b industrial PC that has GPIO pins in it and the BIOS provides settings to configure the state of these GPIOs at boot time, but I need to control them dynamically from Linuxf for use with LinuxCNC instead of an I/O module i wanted to to know if that was possible or not. 

Certainly possible but likely needs a hardware specific driver,
perhaps the RPI GPIO driver could be used as an example.

Honestly I have no idea how to do this so is there a guide or documentation that i could follow because from what i read the pc might have an embedded controller for the gpios that is why when i run gpiodetect on the terminal nothing shows any help would be appreciated.

Have you contacted the manufacturer yet ?

yes but they are not answering

If I see it correctly it has a LPT port?
There are different version I see now. So it has 7 input pins (GPI) and 7 output pins (GPO).
With a XYZ machine you'll have just enough output pins to control the steppers, but like PCW said you'll need to create a driver for it.
If you could still return it, the one with a LPT port might be a better choice. If you want to be more sure that it will work reliable with a fast rate a hardware controller will be a better choice.

Actually, hal_gpio might "just work" in this case.

Try this command and see if it reports the pins: If you get "command not known" then
If the pins are reported, then:
