  • Wireless device remote control by DTMF commands
    Publication number: 20050096030
    Abstract: A wireless communications device, such as a cellular telephone (200), is able to accept and process DTMF tones as commands. Appropriate DTMF tones control operating characteristics of the wireless communications device (200). An example is causing a cellular phone to ring even though it has been configured into a “vibrate only” silent ring mode or a mode which has disabled all incoming call notification. Operation of such a DTMF tone facilitates finding a lost or misplaced cellular phone when that phone is configured to not ring in response to other calls. An external data communications port (232) of the wireless communications device (200) can also be controlled or data specified by the DTMF tone can be transmitted out of that data communications port (232).
