Abstract

PURPOSE:To confirm definitely the transmission of data judging from response to a dummy telegram sent out after final block data during data transmission. CONSTITUTION:The transmitter receives block 8 of a telegram by confirming affirmative acknowledge 7 against request 6 from the receiver. Afterward, blocks are sent over the continuous confirmation of acknowledge 7. The receiver has two buffer units and when data 8 is temporary stored in the 1st buffer while next data 9 is in the 2nd buffer, they are transferred at the timing. Data 10 becomes the transfer data the reception output of data 8. Final block 9 is therefore transferred as transfer data 11 during the reception of next dummy telegram 12, and the acknowledge to dummy telegram 12 is considered to indicate the completion of the reception of the final data.
