Nokia CDMA Modem Setup
I have a Nokia 3105 which is a CDMA phone I am trying to setup an internet connection using the built in modem on a laptop running PClinuxOS 2007 latest release.
I have a DKU-5 cable plugged into the USB and phone I can use the terminal in KPPP to send AT commands and receive responses so the communications link seems ok
If I try to dial the CDMA service using KPPP or wvdial the phone dials the access number but then I get the error "No Carrier" and the phone displays data call ended.
If I use the windows 3g modem driver on a windows xp machine everything works ok, if I use the 2g or data fax driver under windows I get much the same response as linux gives IE the phone dials and hangs up after a few seconds with no carrier.
Hence I believe the modem needs to be setup for 3g so I have tried setting my second init strings as follows
AT+crm=1 this is defined as packet data service relay model
and also as
AT+crm=2 which is packet data service network model
But neither option works, the KPPP log and wvdial both report a response of OK to either command
Does anyone have any ideas?
