Question about set modem power state to off

Hi all,
 
When set modem power state to off, all atoms and interfaces except
'org.ofono.Modem'  are 
 
removed and unregistered. So all APIs execpt 'org.ofono.Modem'  can not
be used after that.
 
But,  when modem power state is off (AT+CFUN=0), some feature should
still be available. such
 
as access SIM card(import contact from SIM) and STK.  I think maybe
ofono should at least keep 'phonebook'
 
and 'stk' atom after set power state to off.
 
 
best regards,
 
Caiwen

What you're thinking of here is the 'Online' property of the Modem which
controls the RX/TX circuit status.  When Online is False and Powered is
True the modem can still access the SIM.  Once the modem is powered off,
it is truly off.

This feature is still in development and thus no driver is currently
taking advantage of this functionality.
