How to Configure BSNL EVDO USB BroadBand in Linux

Configuring the USB in linux is very much similar to configuring any in . 3 steps are involved.

  1. Detecting the device
  2. Configuring .conf
  3. Dialling

In most cases the hardware is auto detected and drivers are automatically loaded. You can check your /dev/ directory for any of these files.

ttyusb0, ttyusb1, ttyusb2 ……

After plugging in he modem, a new device should appear. In most cases it ttyusb0. If no file is appearing then you will have to manually load the drivers by issuing the following command.

modprobe usbserial vendor=0×05c6 product=0×6000

This will load the drivers and make your new device visible in /dev/

Now add the following lines to your .conf

[Dialer Defaults]

Modem=/dev/ttyUSB0
Baud=115200
Dial Command = ATDT
Baud=115200
Dial Command = ATDT
init1=ATZ
init2=AT+CRM=1
Flow Control= Hardware (CRTSCTS)
Username = <your username>
Password = <your password>
Phone = #777
Stupid Mode = 1

Now try the command wvdial in your terminal. It should work.
