Abstract
PURPOSE: To increase the processing capacity of a system, by applying an interruption to the system and at the same time transmitting a pseudo read command to prefetch the screen information from a display terminal device.
CONSTITUTION: A display output controller 11 gives an interruption to a system 1 if the interruption factor exists when a polling signal is received. Then a signal showing the acceptance of the interruption is transmitted. Thus a pseudo read command is given to display terminals 11aW11n respectively that produced the attention inputs. In this case, it does not need so much time to prefetch the screen information by the pseudo read command. After receiving this prefetched screen information, the controller 11 waits for an input of the read command given from the system 1 and then transmits the prefetched screen information to the system 1. As a result, the selection command can be excluded. Furthermore, the channel occupying time can be shortened for a display terminal.
