Abstract

This article relates to a technique to prevent a cursor from being displayed on a screen in specific situations, thereby improving user friendliness of a display. When a large amount of data is transmitted at a relatively high rate from a host to a display terminal to be displayed on its screen, as schematically shown in Fig. 1, a cursor is usually moved so rapidly in the screen that an operator senses bothersome flicker. Thus, it is desirable to erase the cursor in this situation. Further, it is also desirable to take off the cursor during the scroll of the displayed data. On the other hand, when the operator inputs data from a keyboard, the cursor has to be displayed on the screen to indicate the next input position. To meet the above requirements, the display of the cursor is controlled according to the following rules.
