Parallel port problems on new build; pins 14 and 16 not working for spindle

"epp" mode is in the hal_parport manual page, and works for me ( it loads anyway... )

So it does!

linuxcnc.org/docs/2.8/html/man/man1/hal_parport.1.html

I suspect that it might still need to be set in the BIOS?

Setting it in the BIOS only works on built-in motherboard ports.

If the parallel port follows the standard register map, its possible to set
the mode with direct port access. Not sure how hal_parport does it.
I'm wondering if it uses a linux parport driver call which would fail
if the parallel port was not detected by the linux parport driver

Direct port output (outb)

Yeah so why the error message?
I'll try to duplicate this but will need to buy a couple PP cards
Pretty sure I've thrown all the ones I had out when we moved

Can you try loading just one p-port, then the other?

Will do! It will probably be tomorrow before I get a chance to.

Same error message when setting a single parallel port with epp mode, except that it only shows the error message once.

I'll work on putting on some pull up resistors on those pins now.

What version of LinuxCNC?

2.7.14
