ABSTRACT:
A communication terminal apparatus includes a telephone circuit for generating a detection signal in response to a received calling signal in an automatic receiving mode, and a control unit for transmitting an answer-back tone signal in response to the detection signal from the telephone circuit. After transmitting the answer-back tone signal, in response to externally supplied DTMF signals representing a data input start signal, key-in data, and a data input end signal, the control unit sequentially stores the key-in data in a memory and drives a printer on the basis of the key-in data stored in the memory.
