What is the ?

The is a device driver related to Intel's Serial Input/Output (SIO) technology, which provides support for communication between the computer's processor and external peripherals, such as sensors, modems, or other devices that require serial communication.

• UART stands for Universal Asynchronous Receiver-Transmitter and is a hardware communication protocol that allows for the transmission of data between devices, typically over a serial port.
• The 9D28 is a specific identifier for this version of the , which is part of Intel's newer chipsets and is often found on systems with Intel processors (especially in modern laptops or desktops).

This driver ensures that Windows can communicate properly with the UART device, allowing the connected hardware to function correctly.
