Abstract
PURPOSE:To easily and promptly execute the re-sending control by providing a bit for a re-sending instruction during a polling signal, when an error occurs at data from a terminal to load a polling and a next polling to the terminal is executed. CONSTITUTION:First, when a polling P#1 is loaded to a first terminal, #1 data are transmitted from a first terminal in response to this. Next, when a second polling P#2 is loaded to a second terminal, #2 data are transmitted from the second terminal. Further, when the second polling is loaded to the first terminal and the #1 data are received at a system side, an error M is detected. The system side provides a bit N for re-sending instruction in the polling signal P#1 to the next first terminal, and transmits it together with the polling signal. When the first terminal detects that the bit N is provided during the signal P#1, the data transmitted immediately before it are re-sent. Thus, the re-sending control can be easily and promptly executed.
