//
// CSerialMFC - MFC wrapper for serial communication handling
//
// CSerialMFC is a very thing wrapper around the CSerialWnd class,
// which makes it more suitable for use in MFC-based applications.
// Unfortenately, the MFC framework isn't very flexible when it comes
// to adding custom message handlers. We cannot add our own types to
// the message handlers, but we're stuck to use 32-bit integers.
//
// Add the following entry to the window's message map to make sure
// that MFC calls your handler, when a serial message comes in.
//
//      DECLARE_MESSAGE_MAP(CMyClass,CWnd)
//          ...
//          ON_WM_SERIAL(OnSerialMsg)
//          ...
//     END_MESSAGE_MAP()
//
// A typical handler could look like this:
//
//     afx_msg LRESULT CMyClass::OnSerialMsg (WPARAM wParam, LPARAM lParam)
//     {
//         CSerial::EEvent eEvent = CSerial::EEvent(LOWORD(wParam));
//         CSerial::EError eError = CSerial::EError(HIWORD(wParam));
//
//         // lParam: User-defined 32-bit integer (type LPARAM)
//         switch (eEvent)
//         {
//         case CSerialMFC::EEventRecv:
//             // TODO: Read data from the port
//             break;
//         ...
//         }
//         
//         // Return successful
//         return 0;
//     }
//
//
// Pros:
// -----
//	- Easy to use
//	- Fully ANSI and Unicode aware
//  - Integrates seamless in MFC applications
//
// Cons:
// -----
//  - No more then CSerialWnd, except that you need MFC
