Serial ports are a legacy communications port
Serial ports are typically controlled by [[UART]] hardware. This is the hardware chip responsible for encoding and decoding the data sent over the serial interface. Modern serial ports typically implement the [[wikipedia:RS-232|RS-232]] standard, and can use a variety of different connector interfaces. The DE-9 interface is the one most commonly used connector for serial ports in modern systems.
Serial ports are of particular interest to operating-system developers since they are much easier to implement drivers for than USB, and are still commonly found in many x86 systems. It is common for operating-system developers to use a system's serial ports for debugging purposes, since they do not require sophisticated hardware setups and are useful for transmitting information in the early stages of an operating-system's initialization. Many emulators such as [[QEMU]] and [[Bochs]] allow the redirection of serial output to either stdio or a file on the host computer.
