January 9, 2008cell phone Gentoo Handy Hardware Linux modem ppp uiq3 usb
I got my new Sony Ericsson P1i a few weeks ago. Because I hate it to use Windows I wanted to get it working as an usb modem under linux. In my case again under gentoo 😉 My cell phone provider in Germany is Eplus. So if you use this with an other provider you will have to change some values of course. The cell phone itself has SymbianOS on it. The version its called UIQ3. The instructions should work for all QUI3 phones, as far as I know. I used very much sites to get this together, so I beg your pardon that I forgot which that all was.
So first check if you have the need kernel options enabled:
> Device Drivers --> > USB support --> > USB Modem (CDC ACM) support > > Device Drivers --> > Network device support --> > PPP (point-to-point protocol) support > PPP support for async serial ports
If you compiled the things as modules make sure to load them. (and perhaps to autload them via /etc/modules.autoload.d/kernel-2.6)
> modprobe modprobe cdc-acm ppp_async
Of course we need also a ppp dialing program. I choose the normal commandline pppd, but I think this also can be done via some grapical ppp guis. But I did not tested it.
> emerge ppp
There are now only 3 files need to be created. If you use a gui this will perhaps be done via that…
