Abstract
In an information communication system for performing both point-to-point communication and point-to-multipoint communication between a host computer and terminals by using same lines while distributing loads of data communication, data communication report tables are provided on a main storage unit of the host computer for each type of communication. The data communication process is executed distributively at each CPU unit and communication interface unit of the host computer and at each control module of a communication control unit. A plurality of destination pattern tables indicating data destinations are provided for point-to-multipoint communication. For the point-to-multipoint communication, CPU unit designates a particular destination pattern table for each interface unit, and data transmission is requested to each control module in accordance with the destination pattern table.
