Our AVR32 board has a GSM modem attached..
I'd like to send an SMS at power-on, though if we successfully boot Linux
it will do more sophisticated stuff.
If we get the SMS, then nothing further we know the boot failed.
Is there an example anywhere of u-boot talking to a device on a serial
port ( which is not the console ) I can use as an example?

See common/modem.c and search the code for mdm_init().
