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.

WebJul 14, 2024 · RS-232 is a standard for serial data communication between computing equipment. This standard dates back to 1962 but has been substantially revised over the years to accommodate changes to communications technology. At a minimum, an RS-232 connection may consist of a single wire connected between two pieces of equipment.

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. sbb online chatWebJun 30, 2015 · 5 Answers Sorted by: 7 You can control RTS and DTR using SetCommState ().
