特徴とするデータ通信装置。 A data communication device that transmits data from a transmitting side to a receiving side, the transmitting side having a dividing means for dividing the data to be transmitted into a plurality of blocks, and a number for adding a block number to each divided block. and a transmitting means for transmitting data divided into a plurality of blocks to which block numbers have been added; a number storage means for storing the block number of at least the last received data in the data transmission means; a non-reception detection means for detecting that the data transmitted from the transmission means could not be received; and a number return means for returning the block number of the last received data stored in the number storage means to the sending side when it is detected that the data could not be received; 1. A data communication device comprising retransmission means for receiving a block number returned from a retransmission device and retransmitting data from the block next to the received block number.
