carte 3G XU870 Merlin avec ubuntu 8.10

C'est encore plus simple qu'avant ...a condition de ne pas avoir de code pin sur la carte sim !
une fois le code pin supprimé (faites ca avec un téléphone ou via minicom) networkmanager reconnait la connexion et il suffit choisir son opérateur ...

Pour supprimer le code pin via minicom :

CTRL+A and then O
Serial device: /dev/ttyUSB0
Bps/Par/Bits: 115200 8N1
Hardware flow control: No
Software flow control: Yes

Save these settings as default. You may need to restart minicom.
Now, the last output from the modem should be "OK" on a single line. It's time to provide the PIN code (in this example, the PIN is 1234):

at+cpin=1234

Another "OK" should show up which means that the modem accepted this command. The behavior of the LED on the data card should change to single blinks in a blue OR green color depending on the coverage of 3G. The data card prefers 3G when it's available, indicating this with blue blinks. GPRS/EDGE is indicated with green colour.
