I'm trying to add an Oxford Semiconductor 4-port serial card
to puc(4). Using the datasheet, I've gotten to the point where
all four serial ports are probed and attached. However, I don't
seem to be able to communicate through the ports. And, there
doesn't seem to be any real documentation on puc(4). I'm trying
to figure out what the various flags mean. A URL for the datasheet
is:
https://www.semiconductorstore.com/pdf/newsite/oxford/OXPCIe954_ds.pdf
It seems that the Legacy mode (e.g. I/O mapped) of OXPCIe952 is removed
from OXPCIe954. It also seems it has no INTx support, right? Are the device's
com registers not 4 byte stride but 1 byte stride?
Here are the patches that I used to get it started:

It seems FreeBSD's puc(4) support OXPCIe954, so it will help
to see FreeBSD's sys/dev/puc/pucdata.c.
If it's a PCIe addin card, could you tell me the product name?
(I don't say I'll work to support it :))

(If you're trying to use the device for console, you will modify
#if 0'd code in the diff.)
sys/dev/ic/com.c has a lof of #ifdefs. Some of them should not be determined
at compile time (e.g. COM16650 and COM_REGMAP), but the change is not easy.
Please someone(TM) do it.
