serial ports
Sequential data connections
Serial ports are computer interfaces that transmit data one bit at a time over a single channel.
Once standard for connecting keyboards, mice, and modems, they've largely been replaced by USB but remain common in industrial equipment, networking hardware, and scientific instruments.
The term often appears in technical troubleshooting: Check if the device is recognized on the serial port.
