The parity bit is appended to this data for the receiver validation.
The data sent from the transmitter should match at the receiver. Generally, 1 or 2 stop bits can be sent. While sending data, there should be a certain delay between each bit.
This delay is considered as inactive time and the RS line is at negative logic state V. Handshaking is the process of interchanging information signals between the sender transmitter and receiver. These signals build a communication link between the transmitter and receiver. In RS, there are two types of handshaking. They are hardware handshaking and software handshaking. The connectors DB9 and Db25 are used for handshaking purpose.
To send and receive the information without loss of data, it is necessary to maintain robust communication between the transmitter and receiver.
To do that, buffer is used. Buffer is a temporary storage location which allows the transmitter and receiver to store the data until the information is processed by each other at different speeds. In the above diagram, the transmitter and receiver have their own buffer. The transmit buffer holds the characters to be sent to the receiver. While the receive buffer holds the characters received from the transmitter. If the transmitter sends data at a higher speed, the receiver may fail to receive.
To avoid this, handshaking is used. Handshaking allows the transmitter and receiver device to agree before the communication is going to start. The flow control of data transmission and reception is done using hardware handshaking. It stops the data being replaced in the receiver buffer.
Hence, this is known as software flow control. This handshaking requires 3 wires. In this state no data is transmitted. Now, the data transfer takes place. This stops the DTE to transmit the data.
