Irda communication and the Ipaq

First let's see what ipkg list |grep irda tells us... Now let's install opie-irdaapplet. This was all it took to get basic irda support on my Ipaq. But to use your phone as a modem, you need more. There's a nice description in the IrDA Wiki Page.

Using GPRS with your mobile phone

There's a really nice Howto. And a general linux + gprs Howto. The stuff from the general howto worked for me like a charm, after I looked into the siemens settings sheet (there's a link in the howto).

/etc/ppp/peers/s45_gprs:

s45_gprs
/etc/ppp/peers # cat s45_gprs

Managing all from Opie

Now we want to connect and disconnect from opie. Therefor we create some files.

/usr/bin/s45_gprs_on.sh (make executable)

#!/bin/sh
pppd call s45_gprs &

/usr/bin/s45_gprs_off.sh (make executable)

#!/bin/sh
killall pppd

/opt/QtPalmtop/apps/Settings/s45_gprs_on.desktop
