I picked up one of these boards so that I could get an extra serial port on
my Dell (it only comes with one!). I can sort of get it to work but only real
SLOW! I need it to work 19200baud. When I set it up that way, some of the
input coming into the port is lost. All of the output seems to make it.
Unforunately, there's a tens of seconds delay between each character. Here's
my setup info in case anyone can spot what I'm doing wrong:
Bus 0, device 17, function 0:
Communication controller: Unknown vendor Unknown device (rev 0).

I don't know what ttyS2 is?
If anyone could straighten me out, I'd appreciate it!
