What is a UART Controller Windows Driver?

A UART (Universal Asynchronous Receiver/Transmitter) Controller Windows Driver is a software component that enables your Windows operating system to communicate with hardware that uses UART technology. UART is a protocol used for asynchronous serial communication, commonly used in devices like serial ports (RS-232) or embedded systems to exchange data.

A UART controller can be part of a system on a chip (SoC) or it can be a separate integrated circuit (IC). The driver ensures that your operating system can properly manage the communication between the CPU and the UART hardware for tasks like data transmission and reception over a serial connection.
