 Posted: Tue Jul 20, 2004 11:03 pm Post subject: motorola 120c (via USB) as a modem. |
 |
|
I'm trying to figure out how to use my cellphone as a modem to connect to the internet (at a whopping 14.4k). I've done this before on windows, but never on a Linux based distrobution. So where do I get started?
I plug the phone up to my laptop via a USB cable and get:
| Code: | usb 1-1.1: USB disconnect, address 7
usb 1-1.1: new full speed USB device using address 8
cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device
|
This is good right? So A device called ttyACM0 should be the modem. Now how do I connect to it? I'm guessing it has something to do with PPP, or something like that, because I need to dial a phone number (777 to be exact) and enter in a username and password. So I just need some help on getting this to work...
Though im not 100% sure about PPP... The cell phone acts like a normal 56k modem. I just need to tell it to dial a certain number and user a specific username and pass... It doesn't seem difficult but I'm not getting any help searching these forums... To many results which do not relate to the topic *sigh*. |

Ok so far so good. I emerged ppp, and pppconfig. I ran pppconfig, set it all up. Then ran pppd call verizonwireless; it dials my phone (quite fast too) and connects. Whoot! ppp0 comes up; with an IP address. But now I'm lost at how to configure this interface.
Am I suppose to create a net.ppp0 link? If so then how am I suppose to format the conf.d/net file? I've never setup an interface that's directly connected to a provider, so I don't think dhcp or static will help...
Some help please, I'm so close to getting this to work! |

i think ppp should take care of that .. are you using kde?
if so.. i think just by calling kppp it should ask you weather you need to connect or not..
that's rather cool the cellphone used as a modem.. i 've never tried it.. do they charge you fos the used minutes while online? how does it work.. are you paying extra/ |

Right now it's free; I don't get billed anything  . I think they are phasing out this older system (tri-mode CDMA) with the newer GSM internet (<144Kb). Hopefully they don't kill off the 14.4 CDMA data network; I still want to have some fun with it .
BUT: before I did pay normal airtime. If I was on the net for 1 minute, I would be charge 15 cents. (which is kind of expensive for internet). And with the windows software you can manage the address book from your PC. Though I haven't got that working  . |

i'm looking to get my cell phone working under gentoo linux. it works fine under XP of course. i have verizon with a motorola v60 i think phone. i have the mobile office "kit" which basically connects my cell to the usb of the laptop and allows me to dial and get a low speed connection. this uses normal minutes off my plan, but i get nights/weekends free.
i am using udev. when i plug in my cell phone under linux usbview shows an unknown device. i'll have to check the dmesg output to see what goes there.
what module do i need to load for this device? does udev support the module/devices or do i need to manually ad the nodes that should be in /dev area? if so, i could use a little pointer on exactly what i need to mknod to get the appropriate /dev entries.
finally, it seems i'll need to emerge ppp and pppconfig. that _should_ be the easy part i imagine after getting the device recognized.
edit:
ok, i got ppp and pppconfig installed. i rebuilt my kernel to have the modules i think this devices needs. the devices loads ok, but it claims it's binding to /dev/ttyUSB0 (or /dev/usb/tty/0 for devfs). i'm using udev, and no /dev/ttyUSB0 is getting created. i manually created the node, but kppp isn't able to talk to the device at all. it just sends signals and no response. |

finally!!! i got connected using my motorola v60 phone / data cable to the internet!!!
i basically followed the verizon steps listed here:
http://www.linuxdevcenter.com/pub/a/linux/2004/02/05/linux_cellular.html?page=last&x-order=date
| Code: |
robusta root # cat /etc/ppp/chap-secrets
qnc verizon qnc *
robusta root # cat /etc/ppp/peers/verizon
# File: /etc/ppp/peers/verizon
#
/dev/ttyUSB0 # device (NOTE, I MODIFIED THE UDEV RULE IN THE /etc/udev/rules.d/50-* to create this node.
# The following two settings need a corresponding entry in
# /etc/ppp/chap-secrets.
user qnc
remotename verizon
19200 # speed (NOTE... THIS WAS VERY IMPORTANT, IT WOULD NOT CONNECT TILL I CHANGED THIS TO 19200)
defaultroute # use the cellular network for the default route
usepeerdns # use the DNS servers from the remote network
nodetach # keep pppd in the foreground
crtscts # hardware flow control
lock # lock the serial port
noauth # don't expect the modem to authenticate itself
novj
novjccomp
# scripts for connection/disconnection
connect "/usr/sbin/chat -v -f /etc/chatscripts/verizon-connect"
disconnect "/usr/sbin/chat -v -f /etc/chatscripts/verizon-disconnect"
robusta root # cat /etc/chatscripts/verizon-connect
TIMEOUT 5
ABORT '\nBUSY\r'
ABORT '\nERROR\r'
ABORT '\nNO ANSWER\r'
ABORT '\nNO CARRIER\r'
ABORT '\nNO DIALTONE\r'
ABORT '\nRINGING\r\n\r\nRINGING\r'
'' \rAT
TIMEOUT 12
OK "ATZ"
OK "ATE0V1"
OK "AT+IFC=2,2"
OK ATD#777
TIMEOUT 22
CONNECT ""
|
With these scripts in place, I connect via:
| Code: |
robusta root # pppd call verizon
|
The cable (i believe) uses the pl2303 kernel driver to make the phone look like a regular modem and accept AT commands.
| Code: |
usb 1-1: new full speed USB device using uhci_hcd and address 4
usb 1-1: device descriptor read/64, error -71
pl2303 1-1:1.0: PL-2303 converter detected
usb 1-1: PL-2303 converter now attached to ttyUSB0
|
btw, 1k/sec is extremely slow. it's not recommended for browsing today's internet much. if only mozilla had a button to turn images on/off. |
