Hi.
Most cellular telephones have the charging port being a USB connector; are they true USB ports or just use the power pins for charging ? Or goes by brand/model ?
Is there a gadget that will interact with the real world; like transmitting (dialing and sending data) when some conditions meet; or receiving (autoanswering and outputting data) when a call is received ?
Simple examples... By a contact closure, can the phone dial a number as if a door is forced open; or can a remote action be commanded for a relay to close ?
