-- REVISIONS:	Dec 02, 2010 - Added dialog boxes

-- INTERFACE:   WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
                               PSTR szCmdLine, int iCmdShow)
--                      hInstance       - a handle to the current instance

--                      szCmdLine       - the command line arguments
--                      iCmdShow        - specifies how the window should 
--                                        be shown
--
-- RETURNS:     If the function succeeds, terminating when it receives a WM_QUIT 
--              message, it should return the exit value contained in that 
--              message's wParam parameter. If the function terminates before 
--              entering the message loop, it should return zero.
--
-- NOTES:       WinMain is the conventional name used for the application entry
--              point. The standard message loop has been modified to poll the
--              an open serial port if there are no messages on the queue.
