Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0”
This means that it has found a MODEM.. and the basic wvdial.conf has been written..
Now to edit wvdial.conf
Code:
sudo gedit /etc/wvdial.conf
Enter the Dialling number, Username , Passwd etc
My wvdial.conf :
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = *99#
Modem = /dev/ttyACM0
Username = b
Password = a
Baud = 460800
Now to connect
Code:
sudo wvdial
If all has gone right it shd show something like
–> WvDial: Internet dialer version 1.56
–> Cannot get information for serial port.
