WebSince RS422, and RS232 for that matter, have separate transmit and receive lines, they are easier to implement. Of course, there are other matters to consider such as handshaking, but will not be covered in this brief description. Note:it may be easier to use an rs232 to rs485 converter that sits outside the pc. WebDec 12, 2024 · Data transmission process on the RS232. Firstly, from the DTE, RTS generates a request for data to be sent. The DCE side receives the request, and CTS clears the path to receive data. When data is cleared, it will give a signal for DTE side to send the signal. Data transmission starts, bits are transmitted through the RS232 from DTE to DCE.
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.
