I think I've found something interesting here. As you said, the card my
be emulating something with a much larger fifo. Have a look at this one:
http://configure.sh/FreeBSD/serial.html
This patch supports high speed serial "boards", but it might work with
pcmcia serial devices as well. It supports baud rates up to 921600bps,
which is what I am currently seeing com5 set up as in Windows after I
updated the driver.
Is it any limitations in how fast a pcmcia serial card can be set up?
