COM Port
Communications Port. Internal virtual pathways used to transmit data to and from a PC's exterior Serial Port and software running on the PC. The majori- ty of PCs have four Com Ports: COM1, COM2, COM3, and COM4. Most software programs gain access to the Com Ports via system interrupts (IRQs) and only two IRQs are reserved for the four ports. If you have two devices using Com Ports that share an IRQ, you cannot use the devices simultaneously. Typically, COM1 and COM3 use IRQ4, while COM2 and COM4 use IRQ3.
