Some modems shut down the interface if you send +CFUN=0. If that's the case 
for you, you need to override DeviceSetAntennaPower().

Either the interface has been shutdown or the parser has been seriously 
confused. Please post the debug logs.

This depends on the modem. We can't say for sure without debug logs.

As mentioned on IRC before, add the dataOptions() method to your modem class 
and it might work OOTB.
