What is "RTS"?

"RTS" stands for "Request To Send" and it is a signal used in serial communication between two devices.

In a typical serial communication setup, one device acts as the transmitter and the other device acts as the receiver. The transmitter sends data to the receiver using a serial data line, while the receiver sends acknowledgement signals to the transmitter using control lines such as RTS.

The RTS signal is used by the transmitter to indicate to the receiver that it wants to start transmitting data. When the transmitter wants to send data, it asserts the RTS signal, which signals to the receiver that it should be prepared to receive data.

The use of the RTS signal helps to prevent data loss or corruption due to buffer overflows or other issues. By using the RTS signal to control the flow of data, the transmitter can ensure that the receiver is ready to receive the data being transmitted, reducing the likelihood of errors or lost data.

The specific characteristics of the RTS signal, such as its voltage level and timing requirements, can vary depending on the specific communication protocol being used.
