Livebox 2 Sagem: Installation du port série

Après quelques minutes de bidouille avec un voltmètre j'en arrive à la conclusion que le PINOUT du port série de la Livebox 2 Sagem est le suivant :

De Gauche à Droite :
1;2;3;4
(VCC ; RX ; TX ; GND) avec le Reset_Switch ; USB_Connector sur la droite.

En branchant un cable USB to TTL FTDI "TTL-232R-3V3" et en ajustant la position de VCC, RX,TX et GND + minicom en 57600 8N1 on obtient cela : L-232R-3V3 US
