IrDA on Linux

Installing irda-utils

% wget http://www.cs.uit.no/linux-irda/irda-utils/irda-utils-0.9.4.tar.gz

# make install
# vi /etc/init.d/irda
# cd /etc/rc3.d/
# ln -s ../init.d/irda S99irda
# cd /etc/rc0.d/
# ln -s ../init.d/irda K10irda
# mkdir -p /etc/irda
# cp etc/drivers /etc/irda/
# vi /etc/irda/drivers

Let's get ready for IrCOMM

# ls -Lal /dev/ttyS2
crw-rw---- 1 root dialout   4,   66  Mar   4  1999 /dev/ttyS2

add the following two lines in /etc/modutils/aliases (or /etc/conf.modules?)

alias tty-ldisc-11 irtty
alias char-major-161 ircomm_tty (char-major-60 is obsolete, i guess)

It's a show time

1. HotSync -> LocalSync on Palm
2. launch pilot-xfer using Ir port
% pilot-xfer (-p /dev/ircomm) -l (IR-HOWTO Chap. 6 says starting pilot-xfer before starting HotSync on the pilot is not gonna work.)

Relations

# ls -al /dev/pilot
lrwxrwxrwx   1 root     root            5 Sep 30 01:24 /dev/pilot -> ircomm

in my understanding,
/dev/ttyS2 is configured via irattach ttyS2 and connected to /dev/ircomm

Trouble shooting

/proc/tty/drivers /proc/net/irda (only for IrLAN?) /etc/irda/*

# setserial /dev/ttyS2 irq 10
# modprobe ircomm-tty
