Abstract

PURPOSE:To prevent the error transmission between frames and to make easy for frame synchronism, by constituting one character among one frame consisting of a plurality of characters as pause period. CONSTITUTION:One character consists of the start bit ST, stop bit SP and information bits b1 to b3. Further, one frame is composed of the characters ch1 to ch5, for example, and the character ch5 is taken as pause period and the information code is made as the same level as the stop bit SP. Further, frames Fi, Fi+1... are delivered continuously. In receiving this, if there is any error in the reception of character, the processor of the receiver resets the data reception unit, and if no error, pattern collation is made. If in agreement, the reception of next character is made. If the character synchronism is shifted, the data reception unit is reset. On the other hand, if fetched while being out of synchronism, since high level is continued for the pause period ch5 of the end of frame, no out of synchronism continues.
