Re: How to get infrared and/or Nokia working

Hi Christian,

You're not far away from a working setup; everything is working fine
on the system's side, you just have to get gnokii working (see
below). You should already be able to use your phone to establish a
plain old ppp connection (over /dev/ircomm0).

Good !

Use /dev/ircomm0 ;) And gnokii --identify is better for testing.

No idea there. Just try :)

Because you used the wrong device ;)

Only irattach should use /dev/ttyS1, other applications that want to
use the irda link to communicate with another device must use
/dev/ircomm0 (in this case -- there are other protocols that use other
devices, but that's the one for ircomm).

No. I think it's overriden by
* irda-common/selectdevice: serial

And it's only a leftover from my first attempts at getting IrDA
working, IIRC.

Run "dpkg-reconfigure irda-common" as root, you should be prompted
with this question (and the others too).

That doesn't matter.

I can't remember. Probably a leftover or something.

That's good. The ircomm module (and ircomm_tty) will be loaded when

I think (I'm no expert) that there is an IrDA protocol that guarantees
data integrity, and your data is on top of this.

Here's mine :
port = /dev/ircomm0
model = AT
initlength = 1
connection = serial
bindir = /usr/sbin/
use_locking = yes
serial_baudrate = 57600
handshake = software
TELEPHONE = 12345678
timeout = 20

> Thanks for the endurance

You're welcome. I just know how painful it is to get all that working
:) You're not far from getting it working OK. Chances are your 6100
will work with gnokii by using model = AT, just as my 8210 does. [in
fact I'm pretty sure it'll work, as it advertises the same
capabilities as my 8210 does]

Here's the content of my /etc/irda.conf, in case you'd like to compare
with yours :

#irda.conf Version: 1.0
#DONGLE= # specify dongle type
ENABLE=yes # if you do not need to start irattach, set "no"
