Is this really necessary? I'd guess that serial cards are some of the simpler pcmcia targets to enable? (I could be very wrong..) Anyone got an idea about alternative solutions, or can state the minimum binaries/files I need to enable this card? (Advantech COMpad-32/85B-4)


Have you tried just running up a really recent kernel (eg, 2.6.13-rc6)
with PCMCIA and serial (including PCMCIA serial support) built in,
plugging the card in, and seeing what happens?

Yes. I get no message in dmesg indicating that the ports are detected.

Unless I fire up cardmgr, that is.

Testing on a laptop (not the actual target):
