The problem, in short, is that the Telit HE910 does not support sending 
any AT command on the Modem port while there is an outstanding command 
on the Aux port (this should be true for all Telit modems).  Does Ofono 
support synchronizing these two channels so that they effectively share 
a common command queue?  If yes, how?
