    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
    01:54:28 local IP address 10.200.34.104
    01:54:28 remote IP address 192.168.1.136
    01:54:28 LCP terminated by peer
    01:54:28 Connect time 0.0 minutes.
    01:54:28 Sent 0 bytes, received 0 bytes.
    01:54:31 Connection terminated.
    01:54:32 Connect script failed
    01:54:32 Modem hangup
    01:54:32 Exit.

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

    –> WvDial: Internet dialer version 1.60

    Any idea ?!
