That would work, if the modem driver does not implement set_online, 
oFono core automatically transitions to Online after CPIN returns 'READY'.

If the modem resets, then yes you need to call ofono_modem_set_powered 
to FALSE.  Booting it back up should not be done in the driver, unless 
your modem supports so called silent resets.  This is where the modem 
stack crashes but silently resets itself back to the previous state. 
(e.g. no PIN entry is required, initialization is very fast). In that 
case use ofono_modem_reset.

Glad I could help ;)
