COM port

— connector standard RS-232C. Nowadays it is considered obsolete, but it continues to be used as a control port in certain types of electronics — in particular, uninterruptible power supplies, cash registers, and some TVs. Therefore, motherboards with such a connector are also found on the market, although infrequently.
