| Calypso modem usage |
| =================== |
| |
| On the Openmoko Freerunner phone, the Calypso modem is presented by |
| the kernel as serial device /dev/ttySAC0. 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. |
