What is a PCIe to High-Speed Serial Port Windows Driver?

A PCIe to High-Speed Serial Port driver is a software that allows your computer to communicate with and utilize a PCIe (Peripheral Component Interconnect Express) card that provides high-speed serial ports. These serial ports are commonly used for connecting devices such as industrial equipment, embedded systems, routers, networking hardware, or communication systems that rely on serial communication protocols like RS232, RS485, or TTL.

The PCIe to High-Speed Serial Port card (also called a PCIe serial card) is an expansion card that fits into a PCIe slot on your computer's motherboard. It enables additional serial ports (e.g., COM ports) to be added to your system, which may be necessary if your computer lacks built-in serial ports or needs more ports for serial communication.
