Howto: transfer cellular phone pictures to T23 running Linux with Infrared

Linux Distribution: Debian
Laptop: IBM thinkpad T23
Cellular phone: Nokia 6101

BIOS: enable infrared port (Enter BIOS setup at boot by press F1)

Kernel: tested with linux 2.6.22, enable the following option
CONFIG_IRTTY_SIR=m
CONFIG_IRPORT_SIR=m
CONFIG_NSC_FIR=m (this is the chip on thinkpad T23)
and
CONFIG_SERIAL_8250_RUNTIME_UARTS=1 (it's not required, see below)

Installed package: irda-utils, openobex-app

sudo dpkg-reconfigure irda-utils
(Note: most important step is set 'SETSERIAL="/dev/ttyS0"' in
/etc/default/irda-utils
which disable the serial port (see Linux infrared Howto)
I have kernel option set:
CONFIG_SERIAL_8250_RUNTIME_UARTS=1
if not, the port may be /dev/ttyS1, etc)

which modifies two files:

/etc/modutils/irda-utils
-----------clip begin---------
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
alias char-major-60 ircomm_tty

# For dongles
alias irda-dongle-0 tekram
alias irda-dongle-1 esi
alias irda-dongle-2 actisys
alias irda-dongle-3 actisys
alias irda-dongle-4 girbil
alias irda-dongle-5 litelink
alias irda-dongle-6 airport
alias irda-dongle-7 old_belkin
alias irda-dongle-11 ma600

# For FIR device

options nsc-ircc dongle_id=0x09 io=0x2f8 irq=3 dma=3
alias irda0 nsc-ircc
-----------clip end-----------

/etc/default/irda-utils
-----------clip begin---------
# Set your startup settings for irattach, the IrDA-daemon, here.

# Set this to 'false' if you do not need to start irattach. Otherwise set it
# to 'true'.
ENABLE="false"

# Set discovery mode which usually is a good idea for finding other devices.
# If set 'true' or 'false' irattach and sysctl are used to enable and disable
# discovery mode. By default discover mode is disabled.
DISCOVERY="true"

# Set IRDA device to access (e.g. /dev/ttyS1 or irda0).
# In case of irda0, the proper module for FIR-mode has to be set in
# /etc/modutils/irda-utils (2.4) or /etc/modprobe.d/irda-utils (2.6)
DEVICE="irda0"

# Set dongle type, e.g. none, tekram, esi, actisys, actisys+, ep7211, girbil,
# litelink, airport, old_belkin, mcp2120, act200l, ma600). You do not need
# a dongle for FIR mode.
DONGLE="none"

# Set the serial device to quiet with setserial. This is only useful on some
# machines in FIR-mode, so most people should leave it blank. See
# README.Debian for more information.
SETSERIAL="/dev/ttyS0"

# Some laptops (Toshiba Satellites and others with SMCS LPC47N227) require
# running smcinit to initialize the irda device prior to use.
# If you device is one of them, set this option to "yes"
USE_SMCINIT="no"
-----------clip end-----------

Test the setup
start infrared port with
$ sudo /etc/init.d/irda-utils start

then
$ sudo irdadump
pair up the other infrared device, it should show up, i.e.
with lines contain "<" (received packets)

if not, check /var/log/syslog to see if there is error messages

Transfer pictures from a cellular phone (Tested with Nokia 6101)
to send/receive a single file, just use
$ irxfer

to send/receive a group of file, use obexftp
to list folder:
$ obexftp -i -l

use a bash script to get a group of files from "Image" or "Video
clips" folder:

-----------clip begin---------
#!/bin/bash

for i in `seq 0 38`; do
    # filename=`printf '%s%03d%s' 'Image' $i '.jpg'`
    filename=`printf '%s%03d%s' 'Video' $i '.3gp'`
    echo $filename
    # obexftp -i -c Images -g $filename
    # obexftp -i -c Images -k $filename
    obexftp -i -c "Video clips" -G $filename
done
-----------clip end-----------

If finish with IR, stop it with
sudo /etc/init.d/irda-utils stop
