What is the Intel(R) Serial IO UART Host Controller - 43A8?
The Intel(R) Serial IO UART Host Controller - 43A8 is a Universal Asynchronous Receiver-Transmitter (UART) controller on Intel chipsets that allows communication between the computer's processor and peripherals using serial data communication. The UART interface is commonly used for serial communication in embedded systems and other devices that require data transfer over a serial port.
In the context of Intel laptops or desktops, this driver manages the hardware interaction between the system's UART controller and the operating system, allowing various devices (like serial ports, communication modules, or other connected peripherals) to function correctly.
If you're seeing this device in Device Manager with an exclamation mark or a warning, it means the appropriate driver is missing or not installed correctly.
