Cell Phone Modem Configuration

i'm trying to get my cell phone (motorola timeport 270c - CDMA (NOT GSM)) to interface with my laptop (running gentoo linux 2.6.7 kernel) so that i can have a mobile modem.

unfortunately the whole thing isn't communicating, so i'm gonna spew out the var
ious info i have and hope that one of you smart peoples can point me in the corr
ect dirrection.

when i plug the phone into the laptop /var/log/messages outputs:
Aug 4 14:13:24 widget usb 4-1: new full speed USB device using address 2
Aug 4 14:13:25 widget cdc_acm 4-1:1.0: ttyACM0: USB ACM device
Aug 4 14:13:25 widget usbcore: registered new driver cdc_acm
Aug 4 14:13:25 widget drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control M
odel driver for USB modems and ISDN adapters

thusly, they can talk and the kernel module loads correctly....

so then i try to create the configuration file for wvdial so that i can dial out
, and i get this:

/var/log# wvdialconf /etc/wvdial.conf
Scanning your serial ports for a modem.

ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
Port Scan<*1>: S1
ttyS2<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyS2<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyS2<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
Port Scan<*1>: S3 S4 S5 S6 S7

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

so now i'm led to believe that i am supposed to configure my cell phone with set
serial, but i'm completely lost... since it's a USB does it even need a com port
? baud rate? am i going about this in entirely the wrong way? what does /var/log
/messages mean when it says that the device is using 'address 2' (which incrimen
ts each time i disconnect and reconnect the phone)?

note: i've also played around with minicom to try and get some response but have
gotten nowhere.

Hey there,

What kind of an interface does the phone use? Is it a USB? In that case you probably may need to get a driver that can convert USB-Serial interface.

I have an LG 5340 CDMA and I too am having difficulty in connecting to the net as I have not yet figured a way to have the phone modem detected and configured by my RHEL 4 ES.

In windows the driver that came with the phone was a USB-Serial converter. Have not find anything like that for linux, yet.
