It was commited in mainline kernel - i think it's this commit [1] I think that its very good idea - because it will be supported by community and also speed should be better then in user-land process (less userland-kernel jumps). Its interesting, how easy is to backport it to the current kernel. Also its currently in experimental status, so not sure how stable it is (but its not hard to be more stable then qtopia multiplexer ;)). It will also require to use another serial port driver in qtopia device profile, but its not a problem at all. May be i will try it. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
[QtMoko v26] GSM Multiplexer (GPRS)
Hi, After debugging i found that most of gprs related issues are coming from qtopia multiplexer. I decided to try to use external multiplexer with qtopia. For the initial experiment i did: 1) compiled latest gsm0710muxd on debian (i know that there is fso-abyss, but i got some problems on compilation, gsm0710 is much easer to build, so i started with it). 2) Connected to phone using ssh and stopped qtmoko (/etc/init.d/qpe.sh stop) 3) started gsm0710muxd -v and requested virtual channel using dbus dbus-send --system --print-reply --type=method_call --dest=org.pyneo.muxer /org/pyneo/Muxer org.freesmartphone.GSM.MUX.AllocChannel string:$id I got pts /dev/pts/3, and modified /opt/qtmoko/qpe.env with export QTOPIA_PHONE_DEVICE=/dev/pts/3:115200. Also i disabled qtmoko multiplexing in the /home/root/Settings/Trolltech/Modem.conf ([Mutiplexing] section, Active=no). 4) Then i started qpe. It started correctly, detected network, etc. Then i requested another virtual tty (see #3) and started manually pppd on it. From the first view - qtmoko works stable, gprs starts/stops much better, no problems found so far. I want to test this for some time and if it will work fine then i will try to build qtopia with QMultiPortMultiplexer to use external mutiplexer. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
