Serial Ports
overall review score: 3.5
⭐⭐⭐⭐
score is between 0 and 5
Serial ports are interfaces used for serial communication, allowing data to be transferred one bit at a time over a single wire or channel. Historically common in computers and peripherals, they facilitate communication between devices such as modems, mice, and industrial equipment. Although their use has declined with the advent of USB and other modern interfaces, serial ports remain prevalent in certain industrial and legacy systems.
