WebJul 22, 2024 · The RS-232 specification assigns names to flow-control signals. On a PC, the input signal is Clear To Send (CTS) and the output signal is Request to Send (RTS). (The names reflect an alternate usage of the lines to implement a full handshake.) A cable that connects two PCs must connect each RTS output to the other computer’s CTS input. hernan arias https://mtwarningview.com

Are CTS and RTS necessary on UART port?

WebJul 7, 2024 · RTS / CTS Flow Control is another flow control mechanism that is part of the RS232 standard. It makes use of two further pins on the RS232 connector, RTS (Request to Send) and CTS (Clear to Send).These two lines allow the receiver and the transmitter to alert each other to their state.

WebWith hardware flow control (also called RTS/CTS flow control), two extra wires are needed in addition to the data lines. They are called RTS (Request to Send) and CTS (Clear to Send). These wires are cross-coupled between the two devices, so RTS on one device is connected to CTS on the remote device and vice versa. ... WebJan 3, 2012 · RTS/CTS handshaking is implemented by the driver, not the UART. It simply stops writing bytes into the transmitter FIFO when CTS turns off. You'll have the byte in flight plus whatever is in the FIFO that can still be transmitted. This can certainly go wrong if the receiver FIFO isn't big enough and the interrupts are turned off too long.
