Abstract

PURPOSE:To ensure the continuation for the communication control with no intervention of the fault processing routine even in case some fault occurs to the code of answer data ACK, by including even the STK code into the answer monitor to the text transmission. CONSTITUTION:Receiving the transmission order from the main body side, unit B transmits text D1. Unit A gives the error detection to text D1 and then reports the normal reception to unit B when completing the reception with confirmation for existence of no error. Then ACK code R1 and then text D2 are transmitted to proceed to the next face. In case code R1 does not reach unit B due to some reason on the circuit side and thus text D2 is received earlier, unit B detects the STK code which is the head of the data. As a result, the normal completion of preceding text D1 is reported to the main body side, and at the same time the reception is performed for text D2.
