Hi,

I have written a quick infrared troubleshooting guide.

The purpose of this guide is to get your PC and your Phone to communicate !


The following only applies if your IR interface is connected
directly to your motherboard, with a 5 pins connector... as opposed
to a dongle connected to your [external] serial port or other
special IrDA chipsets.
(although the various steps could be usefull for other IR interfaces.)


Step 1
======
Check the /dev/ttyS1 (or /dev/ttyS3 ...)
if irattach is loaded... kill it !
# killall -w irattach
then do a
# cat /dev/ttyS1
if the answer is blank... fine you have COM port here ! (press CTRL-C)
if answer is an "I/O error"... your computer doesn't have such
a serial interface (or setserial is not properly configured..
but i don't think it is possible nowaday) try another "ttyS"

!!! Don't go further if you haven't fixed that !!!

Step 2
======
now start irattach (if it isn't running !)
#irattach -s

BEFORE you activate the infrared on your phone,

#irdadump

should loop something like (where liquid is my hostname) :
#### BEGIN ####
20:11:26.341394 xid:cmd 2990af94 > ffffffff S=6 s=2 (14)
20:11:26.431396 xid:cmd 2990af94 > ffffffff S=6 s=3 (14)
20:11:26.521395 xid:cmd 2990af94 > ffffffff S=6 s=4 (14)
20:11:26.611396 xid:cmd 2990af94 > ffffffff S=6 s=5 (14)
20:11:26.701401 xid:cmd 2990af94 > ffffffff S=6 s=* liquid hint=0400 [
Computer ] (22)
20:11:29.161400 xid:cmd 2990af94 > ffffffff S=6 s=0 (14)
20:11:29.251397 xid:cmd 2990af94 > ffffffff S=6 s=1 (14)
20:11:29.341397 xid:cmd 2990af94 > ffffffff S=6 s=2 (14)
20:11:29.431397 xid:cmd 2990af94 > ffffffff S=6 s=3 (14)
20:11:29.521394 xid:cmd 2990af94 > ffffffff S=6 s=4 (14)
20:11:29.611396 xid:cmd 2990af94 > ffffffff S=6 s=5 (14)
20:11:29.701402 xid:cmd 2990af94 > ffffffff S=6 s=* liquid hint=0400 [
Computer ] (22)
20:11:32.161400 xid:cmd 2990af94 > ffffffff S=6 s=0 (14)
##### END #####
then activate the IR on your phone.

#irdadump

should now print something like :
#### BEGIN ####
20:11:32.521396 xid:cmd 2990af94 > ffffffff S=6 s=4 (14)
20:11:32.611396 xid:cmd 2990af94 > ffffffff S=6 s=5 (14)
20:11:32.701401 xid:cmd 2990af94 > ffffffff S=6 s=* liquid hint=0400 [

20:11:35.161402 xid:cmd 2990af94 > ffffffff S=6 s=0 (14)
20:11:35.251394 xid:cmd 2990af94 > ffffffff S=6 s=1 (14)
20:11:35.341397 xid:cmd 2990af94 > ffffffff S=6 s=2 (14)
20:11:35.431395 xid:cmd 2990af94 > ffffffff S=6 s=3 (14)
20:11:35.521399 xid:cmd 2990af94 > ffffffff S=6 s=4 (14)
20:11:35.601390 xid:rsp 2990af94 < 64cb6936 S=6 s=4 T68 hint=9124 [ PnP
Modem IrCOMM IrOBEX ] (20)
20:11:35.611391 xid:cmd 2990af94 > ffffffff S=6 s=5 (14)
20:11:35.701402 xid:cmd 2990af94 > ffffffff S=6 s=* liquid hint=0400 [

20:11:38.161404 xid:cmd 2990af94 > ffffffff S=6 s=0 (14)
20:11:38.251400 xid:cmd 2990af94 > ffffffff S=6 s=1 (14)
20:11:38.331387 xid:rsp 2990af94 < 64cb6936 S=6 s=1 T68 hint=9124 [ PnP
Modem IrCOMM IrOBEX ] (20)
20:11:38.341394 xid:cmd 2990af94 > ffffffff S=6 s=2 (14)
##### END #####

if not... your Ir interface might not work or (??).


The following should be interesting :

#cat /proc/net/irda/discovery
#### BEGIN ####
IrLMP: Discovery log:

nickname: T68, hint: 0x9124, saddr: 0x2990af94, daddr: 0x64cb6936
##### END #####



Step 3
======
now we can start minicom, but we have to adjust some settings :
the "-s" is important, so we go to the "settings" menu !
# minicom -s
go to the "Serial port setup" and press enter
then press "A" then "/dev/ircomm0"
then press "E" then "e" {we now are "9600 8N1"} then press "enter"
then press "F" once, so "Hardware Flow control" goes to "No" and press enter
then go to "Exit" so we end-up in the terminal...
Minicom should display "Initiliazing" for a few seconds
then there are two possibilities :

"AT..." shows up... fine keep going on...
OR
Nothing gets printed (excepted Minicom's banner)
... do a "killall minicom" on another console (!)
... try again with /dev/ircomm1
... if the same appends again... damned... i don't
    know what is appenning to you !

Once "AT..." has shown-up , try typing "AT i3" then enter...
the modem's response should be "T68 IT Modem"

great, IR is working
press "Ctrl-A" then "Z" then "X" to exit

configure gnokii to use /dev/ircommX
that's it!

I hope this helps.

P.S. for me, i could push the transfer rate to 115000 bit/s
 in minicom.

P.S.2 : if you succesfully configure your T68, please report me
your exact motherboard model and the reference of your IR adapter.
and your config files (gnokiirc and /etc/irda.conf)
