Hello all,

Using Huawei CDMA modem.
Modem hangup just after connection!
Here is the log:

01:54:25 pppd 2.4.3 started by root, uid 0
01:54:27 Serial connection established.
01:54:27 Using interface ppp0
01:54:27 Connect: ppp0 <--> /udev/ttyUSB0

01:54:31 Connection terminated.

Using the same modem with my Ubuntu Desktop, I have the following logs:
