Parallell Port PCI & PCIe Add In Card Info Thread

I'll preface by stating that I don't have any PCI\PCIe cards to work with, tho I thought I did.
I feel it's about that time to attempt to get a centralised one stop thread for the various cards out there that people have got to work and those cards that don't work. Now we are not taking about onboard\builtin parallel ports that typically have the address of 0x378, 0x3bc & 0x278. We are dealing with users who either didn't have a Parallel and had to use an add in card or required a 2nd parallel port card.

I think to begin if we could have the output the command below with the stanza just applicable to the Parallel Port card. If you have a link to the thread that you start to get this card going, if successful that would be great as well.
I would imagine a post could be in the form of, please note that as I don't have a PP card to play with I've used the output for my wifi card, just so you can get a feel for the info. First to post will have their info put in the example if that is ok.

I know guess there will be some overlap on those that work and those that don't. Eventually I'll gather some cards myself and add too the list.
Hopefully what we will end up with is a reliable database & links to threads that have got cards going. And maybe a list that those that are inhabited by evil spirits.

Anyway to all those that get involved Thank You.

Some observations from reading the code for hal_parport and the Linux kernel drivers for the parallel port. Feel free to correct my mistakes.

From what I can gather if your add in card as a PCI ID that the Linux Kernel is aware of, the parallel port card should "register" with the system. If not you may have to "register" the parallel port by something such as:Now this will last between boots but will will come to that at other stage, if in fact it is reliable.
Obviously the IO & IRQ were obtained via
What appears to happen inside hal_parport is that it questions the Linux Kernel regarding the Parallel Port parameters given when initially loading, if in fact the kernel "knows" about it, the hal_parport driver asks for exclusive use, which means if you try to print from an application to a printer that you think is connected the Linux Kernel will not allow this to happen. If the Kernel has no knowledge of a parallel port being then you get the dreaded "Linux parallel port @xxxxx not found". Which is frustrating as you know that the address is reported by the card. So this could be why "registering" or telling the kernel that the parallel port is actually there may work.

The inspiration for this theory and looking at the code came from this thread:
forum.linuxcnc.org/10-advanced-configura...-port-solved?start=0

This is a list of the PCI IDs that the kernel should know about from 4.19.106-rt44-lcnc kernel:

Many thanks Andy, I linked to a post where you did a mini survey.

I've been trolling the interwebs to find as much info as I can. Hopefully the community will be able to create a "one-stop" resource for Parallel Port cards.

If you could do me a favour.

Before running Linuxcnc could you try.

The first dmesg clears the log. Then run Linuxcnc and see if that clears the "Linux parallel port @56320 not found" message and all runs ok ?

I mess up the commands.

Maybe after the next reboot.
