     * @details This project creates a virtual COM port, which loops back data sent to it.
     *          Load the project, connect a cable from the PC to the USB connector
     *          on the Evaluation Kit, and observe that the PC now recognizes a new COM port.
     *          A driver for the COM port, if needed, is located in the Driver/ subdirectory.
