-// Description:
-// SerialConnection.cpp: implementation of the CSerialConnection class.
-// This class opens a virtual comm port to perform read/write operation between PC and hardware
-// through USB cable.
-// This application is used to receive data from the H4 board.An USB driver should be installed on the PC
-// which maps the USB port to the virtual com port.
-// The data received from the hardware is displayed to debug output window.
-//
