Abstract

PURPOSE: To attain the security of a transmission data by providing a transmis sion control system registration means registering respectively an incoming transmission control system set to an incoming communication line and an outgoing control system set to the outgoing communication line by the user utilizing the incoming communication line and the outgoing communication line.
CONSTITUTION: After a connection end data sent from an information processing system 22 is received in a terminal system 21, the incoming transmission control system of the incoming communication line 23 registered by the user in advance by a terminal equipment 25 is set to a terminal side incoming line interface section 26. Moreover, the outgoing transmission control system of the outgoing communication line 24 registered by the user in advance is set to a terminal side outgoing line interface section 27. The incoming transmission control system set to the incoming communication line 23 has the transmission speed of 1200bits /sec and the modulation system of the sent data is the frequency modulation system, and the outgoing transmission control system set to the outgoing commu nication line 24 has the transmission speed of 2400bits/sec and the modulation system of the sent data is the phase modulation system.
