Serial port port.

Serial ports use electrical signals of relatively high voltage: up to +15 V and -15 V. The logical zero level of a serial port is +12 V, and the logical one is -12 V. Such a large voltage drop ensures a high noise immunity. On the other hand, high voltages used by serial ports require complex circuit solutions.
