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. WebRTS/CTS is needed when a hardware flow control is used. It is dependent on the protocol specification rather than on the nature of the endpoints. – Eugene Sh. Nov 17, 2024 at …

WebMay 6, 2024 · Basically DTR is used to indicate the presence of some equipment, and RTS is one half of hardware flow control (along with CTS) to start and stop communication. On USB communication (e.g., using FT232 USB to UART adaptor, etc) the meaning is less clear. DTR is asserted when the port is opened (usually) and RTS is most likely not asserted at all. WebThe RS232 standard defines voltage levels for logical 1 and logical 0. Valid signals are in the range of +3V to +15V (logical zero) or −3V to −15V (logical one) as compared to the 0V ground (GND) pin. On most PCs, a signal level of ±13V is typical for RS232 and ±5V for RS485. Signals between -3V and +3V are invalid.

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. sheridan health services sheridan co
