 * @brief Serial Mouse Driver
 *
 * This file describes the Serial Mouse Driver for all boards.
 * This driver assumes that the BSP or application will provide
 * an implementation of the method bsp_get_serial_mouse_device()
 * which tells the driver what serial port device to open() and
 * what type of mouse is connected.
 *
 * This driver relies on the Mouse Parser Engine.
