Abstract

PURPOSE:To make it possible to perform data transmission and reception easily and accurately by providing a main car telephone set with a handset with dial keys, data terminal equipment connector, operation key switches, display lamps, and speaker. CONSTITUTION:Main body 1 of the car telephone set as a data terminal is provided with handset 2 that has key switches for calling a party subscriber like a push- button dial telephone set on its reverse surface, cable 3 connected to a car-mounting mobile telephone set, data terminal equipment connector 4, key switches 5 for data transmission and reception, light emission diode (LED) lamps 6 showing the state of the data transmission and reception, and loudspeaker 7. To transmit data from main body 1, a party subscriber is called by pushing the dial keys with handset 2 off the hook. Next, the transmission state is set by operating switches 5 after the circuit is connected to the called subscriber with handset 2 off the hook.
