Please make sure that no other modem management software is active. 
oFono requires exclusive access to all tty ports associated with the 
modem hardware.

So if you're running NetworkManager, ModemManager, pppd, etc, these must 
be stopped or configured to ignore the modem hardware you're trying to 
use with oFono.
