A serial port is a communication interface that transmits data one bit at a time over a single channel, making it suitable for long-distance communication. It typically uses a standard protocol, such as RS-232, and features a 9 or 25-pin connector. Characteristics include the ability to support various baud rates for data transfer speed, handshaking for flow control, and the ability to connect peripheral devices like modems and printers. Serial ports are less common in modern computers, having largely been replaced by USB and other faster interfaces.
