Im using my Samsung i730 phone as a wireless CDMA modem tethered via USB to my IBM Thinkpad 560z running DSL 2.2. Service provider is Verizon Wireless and Im on their unlimited $45/mo data plan.

How to hook up: -

1) hook up the phone over USB - either using the cradle or a 3rd party cable. (Note: The phone will also charge itself from USB while connected - cool).

2) DSL Panel -> DIalup -> Config -> Create

3) Choose Dynamic DNS

4) PAP -> yourtendigitphonenumer@vzw3g.com
password is 'vzw'
speed is 921600
choose Tone
number to dial is #777
Answer no and manually select serial port as /dev/ttyACM0

5) Summary should look like this...

Number #777 Telephone number
User yourtendigitphonenumber@vzw3g.com ISP user name
Password vzw ISP password
Speed 921600 Port speed
/dev/ttyACM0 Modem com port
Method PAP Authentication method

6) Select 'Finished Write Files and return to main menu'

7) Select 'Quit Exit this utility'

8) open a Terminal and ...

sudo vi /etc/ppp/peers/<name you saved it as>

9) Add the following lines at the bottom...

persist
lcp-echo-interval 0
lcp-echo-failure 0
crtscts
debug

These stop the line from timing out because Verizon doesnt seem to
reply to PPP LCP Echo requests. The last line turns debugging on
that you can see when you dial - you dont need this if it all works :-)

10) on your i730 - dial number **PATH (**7284) and a secret menu will appear.
Select USB modem and hit OK

11) DSL Panel -> Dialup -> Enter the name you save the config as
Click Dial

Alternatively pop and term and run 'sudo pon <name of config file>'

12) Bingo! you should be surfing.

After some hacking I can also use the phone as an untethered CDMA modem using bluetooth under Windows XP using a IOGear bluetooth USB dongle, but Im not sure where to start with DSL. Im not sure if there are bluetooth drivers in the kernel?

Im getting a lot of stalled downloads now. Looks like it might be this problem:

( see < http://kenkinder.com/evdo-pc5740 > )

Does anyone know a fix or where I can get a patched 2.4 usberial module?

Is there anyone with the kernal source installed who could build me a usbserial.o binary with this patch installed? Would be much appreciated.

PG :-)

Doh! looks like the usbserial module isnt even used for this connection so it must be something in acm or usbcore. :-(
