Abstract
A plurality of work stations each imparted with a multi-window control function are interconnected through an integrated service digital network (ISDN), wherein control communication route is established among a plurality of stations between which interlocutory communication are to be performed. The work stations transfer control commands by way of the control communication route in accordance with operation by users under the control of an interlocution control program to thereby establish or disconnect a logical communication route between designated application programs of the work stations. So long as the logical communication route is established, the application programs can execute data processing in cooperation with each other. In that case, identical change of display in the windows corresponding to the application programs, respectively, takes place in the work stations. User can perform conference or document edition processing by designating the position of data of concern by a pointing object while conducting conversation by using a telephone set installed at the work station.
