[SOLVED] Please help in setting up Airtel MobileOffice

[thinkfree]

Please help. I am connecting using data cable on Airtel and wvdial.conf looks like that

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Phone = *99#
ISDN = 0
Username = none
Init1 = ATZ
Password = none
Modem = /dev/ttyACM0
Baud = 46080
stupid mode = 1

But when I try to connect I get the following message in terminal

--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

The result is same for Ubuntu, Fedora and OpenSuse

Does the system recognize it as a modem? Is the proper driver loading?

Enter this command in a terminal, and post the output here:

lsusb

You can also check the output of this command, after inserting the modem into a USB port:

dmesg

This will output system messages. To view the messages live, as they happen, use this command. You will need to be root, so use su or sudo;

tail -f /var/log/messages

Make note of the port it is assigning to the modem, such as 'ttyUSB0' or similar.

Yes it was being recognised as a modem, and even connectionn was made. But it disconnected just after connecting. After 3 days of hard work, I found the solution. Editing the wvdial file as following worked.

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","airtelgprs.com"
Modem Type = USB Modem
FlowControl = Hardware(CRTSCTS)
Dial Command = ATDT
SetVolume=0
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
Inherits = Modem0
ISDN = 0
Phone = *99***1#
Mode = 1
Password = b
Ask Password = 0
Username = a
stupid mode = 1
Compuserve = 0
Idle Seconds = 2000
Auto DNS = 1
