Abstract

PURPOSE:To prevent the leakage of confidential information for data communication and facsimile communication, by providing a logical terminal number being a specific address designation in a start signal to a reception terminal. CONSTITUTION:A transmission side terminal transmits the information to be transmitted to a reception terminal and the required information such as the designation of a remote terminal, and in the required information, the information to discriminate if a telegraphic message is a normal telegraphic message or a specific telegraphic message and a logical terminal number being the designation of address when the specific telegraphic message, are provided. The reception terminal can output the telegraphic message immediately when the normal telegraphic message. In case of the specific telegraphic message, the entire telegraphic message is once stored in a storage device, a pass word is inputted to the terminal, and if the pass word and the logical terminal number are coincident, the message is outputted from the storage device and outputted.
