Quote:BSNL has launched EV-DO based wireless broadband all over India and become the first EVDO service provider in India.

I have successfully connected GNU/Linux system to Internet using this service. The system used is a laptop Acer Aspire 5573 with Fedora core-8. The procedure is described below. The procedure given is very brief, I will expand it once time permits.

1. Ensure your EVDO connection is activated by BSNL. You will be provided with a user name of 10 integer size and a password of 4 integer size.

2. Connect the EVDO data-card to one of the USB port of your system. You can ensure the device availability by the command

Code:

$ lsusb

The EV-DO USB data card provided by BSNL is manufactured by ZTE Corporation. However when this device is probed using lsusb command, the device vendor will be shown as Qualcomm.

3. The device file of this card will be ttyUSB0. It this device is not created automatically, you can create it with following command with root privilege .

Code:

$ modprobe usbserial vendor=0x05c6 product=0x6000

4. You can verify the success of the operation using

Code:

$ dmesg

If device is detected properly, the output message will contain some thing like following line

Code:

usbserial_generic 2-2:1.0: generic converter detected

      usb 2-2: generic converter now attached to ttyUSB0

      usbserial_generic 2-2:1.1: generic converter detected

      usb 2-2: generic converter now attached to ttyUSB1

      usbserial_generic 2-2:1.2: generic converter detected

      usb 2-2: generic converter now attached to ttyUSB2

5. Now you EVDO set-up ready. You can connect to Internet by setting up a ppp dial up connection with following details. (I have used kppp)

Modem device : /dev/ttyUSB0
Connection baud rate : Up to 921600
Dail to : #777
Username and password : As provided by BSNL.

6. To automate the device detection add a new udev rule to your system.

Open a file ‘70_bsnl_evdo’ in /etc/udev/rules.d directory and add following content in single line.

Code:

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6",  ATTRS{idProduct}=="6000" RUN+="/sbin/modprobe usbserial vendor=0x05c6 product=0x6000"

Hi, ppl. Vimal here. Thanks go out to sathya for posting the link (lazy old me... hehe )

Just thought i'd bump it up with a newer resource that turned up in a Google Search.
This one uses 'wvdial' instead of Gnome/kde ppp clients, and is considerably more detailed. Kudos to the original author.

More power and enthusiasm to all fellow Linux users. lets hack this baby. I'm planning on messing with the network stack and tweaking Tcp window size and buffers once I get the modem (and I figure out WTF i was just talking about. lol). talk about being way in over my head in enthusiasm.

yup, ppl.
May not look like much, but this device has the maximum hack potential of any other gadget out there.(barring any obscure open sourced toys that certainly aren't available in the same price range as the n800 ~ $230-250 )

Everything about it screams : "Play with meee!" heh heh ... even sounds naughty.

I have read in couple of sites that airprime module offers much better performance than modserial.

Sathya, Can you write a tutorial that uses airprime?

[dukelordx]

I'll give EVDO a try in Cochin under ubuntu. So far i've been only using CDMA towers in rural areas. modserial is not a bottleneck at these medium speeds.
