What Is a PCI Serial Controller?
- Serial controllers connect modems, data terminals and computers to the motherboard using a serial port. Serial ports were common until around 1998, when the faster USB and FireWire ports became well-established
- Definition: PCI, which stands for Peripheral Component Interconnect, is an input/output peripheral bus standard. PCI uses buses as pathways that connect peripheral devices like the keyboard, mouse, monitor and printer to the motherboard
- Function: PCI serial controllers use the PCI bus to provide a data path between the central processing unit and an external device. Although serial ports work at low speeds, they can be useful for connecting older devices to a motherboard
- Components: A PCI serial controller is composed of a printed circuit board with two rows of gold "feet," or pins, that connect to a slot on the motherboard. A row of small capacitors near these pins filters out noise
