After the successful transmission of a packet, next packets are transmitted until entire message is sent. If a packet is received and contains errors, the receiver will send a negative acknowledge. This implies that the sender has to send it again.

Data bytes contain data according to the ASCII code for text or simply a value between 0 and for binary data. Control bytes determine the behavior of the communication link, and are used for a range of different purposes. The link between sender and receiver is half duplex. Bisync organizes data into block of up to characters, which are sent over the link sequentially one-at-a-time as shown in Figure. The receiving device independently calculates the BCC and compares the two calculations.

From the Figure, it can be seen that each message has three parts:. SYN characters are used to establish synchronization between the sender and receiver. The message block follows the SYN characters. In this scheme, sender breaks each message into blocks of small messages for transmission. The trailer for each block consists of a block check character BCC. Both the sender and the receiver generate distinct BCC during the transmission of message.

At the end of receiving the trailer, the receiver compares its own BCC against that of the senders. If they are the same, this indicates the block has been successfully received without any error. In this case, the receiver will reply using a positive acknowledge ACK. If the BCC of the receiver does not match that of the sender, the receiver knows an error has occurred during transmission, and will instruct the sender to retransmit the block by replying with a negative acknowledge NACK.

This is also explained with the help of Figure. Bisync scheme has one major disadvantage in distinguishing between the control characters and the same text in a binary file. If a control character like ETX occurs in the text field, the receiver would interpret this as the end of the text field and take the next character as the BCC.
