Out of curiosity I just had a look at i386's GENERIC configuration
file and the below comment caught my attention:

# Plug-and-Play BIOS and attached devices
...
# com port
# If enabled, consider changing "com0", "com1", and "com2" under "ISA Serial
# Interfaces" to "com*", otherwise com2 will attach at pnpbios? and there
# will be no com0.  A side effect is pcmcia (and other) com? previously
# starting at com3 may attach as com1 or com2.


Although this didn't seem to be _directly_ related to my problem, I
gave it a shot anyway and outcommented the following lines in my kernel
config file:

com0    at isa? port 0x3f8 irq 4        # Standard PC serial ports
com1    at isa? port 0x2f8 irq 3

After the removal of these two lines, com2 in my dmesg output is gone
and I now have com0 attached to pcmcom0:

com0 at pcmcom0 slave 0: ns16550a, working fifo

Unfortunately, com0 (i.e. dty00) is not functional. It behaves exactly
as dty02 in my previous post. And com1 is missing altogether.

Any ideas?

Cheers,
Joerg
