EVDO on Linux

Here is a tip on how to setup the EVDO on Linux. Since the EVDO vendors are not shipping any softwares to support EVDO on Linux, this post might be helpful.

1. Plug your EVDO to the USB port.
2. As a root user type

   lsusb

3. Look for the vendor ID and the Device ID (for BSNL it’ll be 05c6:3197). Note it down.
4. run (Use ID’s from step 3)

   modprobe usbserial vendor=0x05c6 product=0x3197

5. run

   gedit /etc/wvdial.conf

   and add the following line

[Dialer Defaults]
Modem=/dev/ttyUSB0
Baud=921600
Dial Command = ATDT
Baud=115200
init1=ATZ
init2=AT+CRM=1
Flow Control= Hardware (CRTSCTS)
Username =
Password =
Phone = #777
Stupid Mode = 1

Now you can connect to the internet using wvdial.

Note: The modprobe method will not work with newer linux kernels as usbserial is integrated in kernel. See this post for kernel boot configuration.
