Serial Port. Even though the communication in PS/2 and USB is serial, technically, the term Serial Port is used to refer the interface that is compliant to RS-232 standard. There are two types of serial ports that are commonly found on a computer: DB-25 and DE-9.
The most commonly used serial port card is the PCMCIA card or PCI serial card, probably because these are easy to insert and start using in any desktop or laptop computer with a standard PCMCIA port slot or standard PCI card slot.
