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.
