Hello.
  Is it possible to use 3400's IrDA port under NetBSD 1.6.2 ?
This PowerBook has only one serial port, but dmesg shows:

zstty0 at zsc0 channel 0
zstty1 at zsc0 channel 1

So I wonder if zstty1 is used by internal modem (which I do not have), or
by IrDA?

I understand that zstty1 is represented by /dev/tty01?

pbook: irdaattach tty01
irdaattach: TIOCSLINED: Device not configured

TIA
Radek
