I'm not entirely sure what you mean with "power off" and "shut down the radio", but here are the definitions I'm using: power off: the entire modem is powered off not just the radio. The device does not communicate with the host because it is unpowered. radio off: the radio is powered down and no network communication is possible, but the modem can still communicate with the host. The ModemManager API specification would not allow CFUN=5 for the "disabled" state, since it defines the disabled state as not allowing network communication. So I would still use CFUN=4 for "disabled" state. But couldn't the modem instead be set to CFUN=5 whenever it is enabled? The Telit docs seem to say it's a fully functional state, just that the modem can do some power saving. Which sounds like a win without a downside.
