CONTROL SYSTEM FOR PLURAL LOGICAL TERMINAL PICTURES

摘要

PURPOSE:To automatically display a picture of a logical terminal whose picture is not displayed when the logical terminal concerned display data from a host and its picture data are changed. CONSTITUTION:A terminal equipment 1 is connected to a host computer 2 through a communication line 3. A picture change management table 5 receives display data from the host 2 and registers a picture change. A key input control part 7 reports that a transmission key on a keyboard 9 is depressed and the logical terminal displaying a picture is changed to a transmission status. A logical terminal picture control part 4 receives the change information, retrieves the table 5 and outputs a picture display request for the logical terminal whose picture is changed. A picture display control part 6 receives the picture display request and executes the display control of a display 8.
