To allow oFono to +autodetect and use this, a simple udev rule is needed: + +KERNEL=="ttySAC0", ENV{OFONO_DRIVER}="calypso" + +You can put this in any file in /lib/udev/rules.d. A logical choice +is the "55-openmoko-gta01-gta02.rules" file, if it exists in your +Freerunner distribution. + +With this rule in place: + +- oFono will detect the Calypso modem when it starts up, and the + `list-modems' test script will show this, but will not power it up + +- the `enable-modem' test script can be used to power it up + +- a subsequent `list-modems' will show lots of information, including + network registration. |
