In fact, MF192 has two modes: PPP device, and pseudo-ethernet device. It can be switched using %USBMODEM command. So, command AT%USBMODEM=0 disables internal CD-ROM and enables cdc-ether device. In this mode the modem just works without any patching: (ttyACM0): --> 'AT%IPDPCFG=1,0,1,"mts","mts"<CR>' (ttyACM0): <-- '<CR><LF>OK<CR><LF>' (ttyACM0): --> 'AT%IPDPACT=1,0<CR>' (ttyACM0): <-- '<CR><LF>ERROR<CR><LF>' mm_serial_parser_v1_parse(): Got failure code 100: Unknown error (ttyACM0): --> 'AT%IPDPACT=1,1<CR>' (ttyACM0): <-- '<CR><LF>%IPDPACT: 1, 2, 0<CR><LF><CR><LF>OK<CR><LF>' (ttyACM0): <-- '<CR><LF>%NWSTATE: 4,25001,3G-HSDPA,-,0<CR><LF>' (ttyACM0): <-- '<CR><LF>%NWSTATE: 4,25001,3G-HSDPA,HSDPA-HSUPA,0<CR><LF>' Meanwhile, originally modem was configured as PPP device, so it is not working "out of the box", and this is a bug. I think that ModemManager uses incorrect tty-port for data, but I don't know how to find out and fix this. -- Alexander Orlov _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list
