Use cell phone as modem
 

Hi,
I have a Samsung SPHA660 cell phone. I got a cable for it to use it as a modem with my laptop, so that I can dial into a dialup ISP and use the internet on the road. The cable connects to the phone via a USB cable. In Windows XP, it was almost like the cable turned it into a virtual serial port, and I connected to the phone through it and could just do ATDT5555555 or whatever and it'd dial up, just like I were using a normal serial port (after the installation of the driver for the cable). I would like to be able to use this in linux, however, I am not sure how I would go about getting it to work. Anybody have any idea what kernel modules or program I would use to get this working?

Thanks,
Marshall

Edit-- Oops, I guess this was suppost to be in the hardware forum. Sorry.

Check out here http://tuxmobil.org/laptop_manufacturer.html for a start. There might be one just like yours listed there or similar previous model. Read many of them and you can figure out what you need to do pretty easily.

Kernel should more than likely be ready. Open a console terminal session and plug in the cell phone to computer. Use the dmesg command to see if it is seen and what it maybe defined as. Post output if confused or not.

As far as software the only thing that pops in my mind is rfcomm on USB cell modem.

Check the HCL section here. There might be something in there as well. If not and you get it going please post what you did in there.

Not sure of your phone service provider but Verizon offers low speed 14.4k connection to there service for the price of your minutes. A higher speed service is available for fee. Same with afew others.

My phones all use the module cdc-acm

If the module is not loaded nothing interesting will happen. If you load the module then you will see in your log file that the modem is assigned to a device name such as ttyACM0.

Then you can simply use the device as a modem.

The module was called acm in the 2.4 kernels

Alright, I'm going to have to recompile my kernel modules to get the cdc-acm module, I'll post here on how it works out. Will it still show up in dmesg when I plug it up if I do not have that driver in?

depends on your syslog settings, you will get your standard usb messages but the device will not get assigned without the module.

try /var/log/messages

also you can use usbview if you have it.


you should verify that yourphone uses that module.
