<p>PURPOSE:To add a control function using a consecutive zero signal by identifying a character bit whose entire bits are zero and the consecutive zero signal at the receiver side. CONSTITUTION:A signal (a) being a data sent by a sender side terminal equipment 1 is sent to a transmission line as a signal (b) through a transmitter 4. The signal is given to the receiver 5 and led to a receiver side terminal equipment 2 at the reception side. Then a consecutive zero signal sent by the sender side terminal equipment 1 is sent in a way of being identified from a character bit whose full bits are logical '0'. Thus, new control using the consecutive zero signal is attained in addition to the control by a conventional character data with respect to the receiver side terminal equipment 2.</p> |
