Hi.

I thought to examine whether protocol stacks work,
and tried connecting between Linux/i386-IrDA machine
via an actual serial port.

I connected two machines via cross-wired serial cable:

<host #1>
  machine: laptop PC
  system:  Linux/i386 - kernel 2.2.13 & irda-utils-0.9.5

  # irmanager -d 1      (but /etc/irda/* not exists)
  # irattach /dev/ttyS0 (COM1: actual serial port)

<host #2>
  machine: PowerBook G3 233/14" (Wallstreet)
  system:  Linux/ppc - kernel 2.2.14pre & irda-utils-0.9.5

  # irmanager -d 1      (/etc/irda/* not exists)
  # irattach /dev/ttyS0 (modem/serial port)

As result, irdadump seems to work.
Both hosts detected the another host.

Continuously, I tried IrLAN.
On both hosts, involked "modprobe irlan" and could see "irlan0"
with ifconfig.

But, assigning IP address to irlan0, Linux/i386 machine hanged up...
LinuxPPC machine did not hang up.


Because discovering did work with serial port and formerly failed
with PowerBook's built-in IR-port, I think that transceiver/receiver of
PowerBook's IR-port cannot be activated with simple serial port drivers
and they are activated via special output ports.
