I just bought a no-name USB-to-phone serial cable on eBay, hoping to use my mobile phone as a modem from Linux. Everything appears to be going fine when I connect it to my laptop(debian unstable 2.6.0 kernel):

Jan 27 20:22:11 localhost kernel: pl2303 1-1:1.0: PL-2303converter detected
...
Jan 27 20:22:11 localhost kernel: usb 1-1: PL-2303 converter nowattached to ttyUSB0 (or usb/tts/0 for devfs)

The problem is that when I connect my Nokia 3589i phone to it, I'munable to communicate with it. I've tried using minicom to send modem commands directly to the /dev/ttyUSB0 port, but this doesn't do anything. I've also tried gnokii, the linux Nokia phone manager program. No luck, the phone's display doesn't even indicate anything.

I'm not sure if there's something wrong with my cable or whether it's aproblem with the software or what I am doing wrong. Any advice would be greatly appreciated!!

Are you sure your phone has the capability to act as a modem?

Yes, Nokia in fact sells an "official" cable for the phone ... But it doesn't work with Linux apparently. These generic usb-to-serial cables are supposed to work fine. So I'm kind of confused.

I can tell you that the pl2303 works for my usb2serial adapter, Model GUC232A.

Do you have a way to test the serial port?

I don't know how I can test the serial port alone without testing the phone as well. See, the cable correctly identifies itself as a pl2303, and minicom is perfectly happy to send modem commands to /dev/ttyUSB0, but nothing seems to get through to the phone.

Do you know of a good way to test the serial port?

Thanks!

Only by sending and receiving data to something. You could check for voltages but that's not really going to prove anything.


We have a nokia at work that refuses to work with a data connection. Using windows it just says no dial tone. The phone does nothing.


I have not hooked up a nokia to my system, but my motorola needs a driver for the modem. However it connects to USB.

I load it like this, modprobe acm

Then I can communicate with it through /dev/ttyACM0.

Hmmm. So some Nokias don't work with data connections? Do you know what model it is that doesn't work? I hope that's not mine, which is a 3589i. Thanks for the info!

I'll check when I get back out west. Leaving tomorrow, so I'll check it out Friday and let you know. I suspect it's a problem with the phone, but it might be the device. It should work in my opinion, but it doesn't.

Please let me know if you can get the data cable to work with linux. I have Suse 9.0 Pro installed on my laptop and would very much like to plug my nokia 3589i cell phone into it so I can dial up on the go .

I tend to drop my 3589i on the ground quite abit and it seems rather glitchy, for instance theExtended Network message sometimes looks like matrix charectors when it first boots and I know Ive had friends that have had bad luck with these phones glitching out after they are dropped on the ground. I know this probobly has nothing to do with it not being able to communicate properly via the data cable. Has anyone else had problems with these nokia phones?

I would really like to get linux loaded on this phone via the data cable as well, so I hope someone can solve this problem

What kind of cable is it. If it's USB then plug it in and watch /var/log/messages or your log file for your system. It should say something about the driver loading and the device name, etc

If the modules is not found load the driver acm or maybe cdc-acm for 2.6 kernels

I have a Model GUC232A as well. I am trying to use it to talk with Cisco equipment; however, I am not having any luck.

I see the device /dev/ttyUSB0 be created. When I attempt to get Minicom to use it to communicate, nothing happens. I've checked/changed the permissions on the device to allow everyone rw access to it, but I am not able to get anything accross. When I have the Router off and turn it on, I get blinking lights like data is flowing, but minicom does not display anything.

Anyone have a suggestion?

Thanks!
