I have actually made some progress on this serial port card! I looked at how
FreeBSD has it configured, tried to map the values to the OpenBSD struct, and
actually got something working!
I added the following to pcidevs:
vendor PERLE 0x155f Perle
vendor COMTROL 0x11fe Comtrol
product PERLE R35583 0xb008 Speed8 LE
product COMTROL 5002265 0x0805 RocketPort uPCI Octa
I added the following to pucdata.c:
{
{ PCI_VENDOR_PERLE, PCI_PRODUCT_PERLE_R35583, 0, 0 },
{ 0xffff, 0xffff, 0, 0 },
{
{ PUC_COM_POW2(0), 0x10, 0x0000 },
{ PUC_COM_POW2(0), 0x10, 0x0008 },
{ PUC_COM_POW2(1), 0x10, 0x0010 },
{ PUC_COM_POW2(1), 0x10, 0x0018 },
{ PUC_COM_POW2(2), 0x10, 0x0020 },
{ PUC_COM_POW2(2), 0x10, 0x0028 },
{ PUC_COM_POW2(3), 0x10, 0x0030 },
{ PUC_COM_POW2(3), 0x10, 0x0038 },
},
},
And much to my surprise, it shows up (with some issues) and when i connect 2
of the ports with a null modem adapter, i can cu from one to another!
(For now, I’m not too concerned about the RocketPort card)
The dmesg looks like this:

Now some questions:
I first listed all 8 ports with PUC_COM_POW2(3) because I think I saw a
similar device (a Boca card or something) using it. it worked fine (one of
the ports was connected to a different machine an cu could pass text). I then
changed the numbers passed in (to 0, 1, 2, 3) just to see if anything changed,
and the first and second ports can still talk to each other. What exactly
does that value do?
Why do the first four ports probe to 16 bytes but not the next four? I read
somewhere that this card has two four-port chips, so that why it is recognized
as two devices. It’s just strange that some have the probe depth message
and some don’t.
What is up with the “couldn’t get subregion” message? I did a search
and couldn’t find anything about that string on the Internet.
This is my first real attempt at development of this type so I am pretty happy
about this. I would love for 5.9 to have support for this card. I also have
a couple RocketPort cards and I could probably send one to someone if they
would want to work on it.
