Abstract

PURPOSE:To increase the transmission efficiency of data, by responding the result of error check of each block of text at a bundle, after the end of reception of one text. CONSTITUTION:A transmission control section 2 transmits a text block, an ETB code, a CRC code as to blocks 1-7 together with a termination code ETX in place of the ETB code of a block 8. A reception station detects at 7 and transfers it to a reception controller 8. Thus, a CRC control section 10 starts the CRC calculation of the reception data. When the code ETX is detected at 7, after the control section 8 sets the result of CRC comparison to a response flag register, it transmits the result of CRC comparison of each text block.
