Trouble tethering samsung phone.

[stevovo]

Could somebody please help me before I rip my hair out

I'm trying to get a samsung e370 phone to connect as a modem on linux but it keeps disconnecting about 3 seconds after it connects saying that the modem has hung up

Here is the output from wvdial:

--> WvDial: Internet dialer version 1.53
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
ATQ0
OK
--> Re-Sending: ATZ
ATZ

--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: AT+CGDCONT=1,"IP","INTERNET"
AT+CGDCONT=1,"IP","INTERNET"
OK
--> Modem initialized.
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#
CONNECT
--> Carrier detected.  Starting PPP immediately.
--> Starting pppd at Thu Feb 19 11:27:35 2009
--> pid of pppd: 16914
--> Disconnecting at Thu Feb 19 11:27:39 2009
--> The PPP daemon has died: A modem hung up the phone (exit code = 16)
--> man pppd explains pppd error codes in more detail.
--> Try again and look into /var/log/messages and the wvdial and pppd man pages for more information.

Here is my wvdial.conf file:

[Dialer Defaults]
Stupid Mode = yes
Modem Type = Analog Modem
Phone = *99#
Username = ;
Password = ;
Init1 = ATZ
Init2 = AT+CGDCONT=1,"IP","INTERNET"
Modem = /dev/ttyACM0

Here is the last few lines of debug output from pppd:

Sorry for such a long post, dont wanna leave anything out

The phone works fine on a windows machine.

I can use a samsung u700 on the same linux machine and the exact same commands ands files work (except the ttyACM0 is ttyUSB2 though)
