Yep, I forgot about that one. Sorry.

But you DO see two ttyXY messages during boot up, do you?
What do "setserial /dev/ttyS0" and "setserial /dev/ttyS1" report?

I've also attached my /etc/rc.d/init.d/irda startup script (which just
calls irmanager -d1).

case "$1" in
  start)
        # Start daemons.
        echo -n "Starting irmanager: "
        daemon irmanager -d1
        echo
        touch /var/lock/subsys/irmanager
        ;;
  stop)
        # Stop daemons.
        echo -n "Shutting down irmanager: "
        killproc irmanager
        rm -f /var/lock/subsys/irmanager
        echo
        ;;
  status)
	status irmanager
	exit $?
	;;

	$0 stop
	$0 start
	exit $?
	;;
  
  *)
        echo "Usage: named {start|stop|status|restart}"
        exit 1
esac

exit 0

Then, I've got /etc/irda/drivers:


--=-=-=
Content-Type: application/octet-stream
Content-Disposition: attachment; filename=drivers
Content-Description: /etc/irda/drivers

#! /bin/sh
#
# drivers
#
# Initialize and shutdown IrDA device drivers.
#
# This script should be invoked with two arguments.  The first is the
# action to be taken, either "start", "stop", or "restart".
#

action=$1
device=$2

case "${action:?}" in
'start')
	irattach /dev/ttyS1          # The second serial port is an IrDA port
	setserial /dev/ttyS1 spd_vhi
	setserial /dev/irnine spd_vhi
    ;;
'stop')
	killall irattach             # ... or something. Currently not used
    ;;
'restart')
	/sbin/ifconfig ${device:?} down up
    ;;
esac

Let's know what the setserial stuff reports.
