// CSerialWnd - Win32 message-based wrapper for serial communications
//
// A lot of MS-Windows GUI based programs use a central message
// loop, so the application cannot block to wait for objects. This
// make serial communication difficult, because it isn't event
// driven using a message queue. This class makes the CSerial based
// classes suitable for use with such a messagequeue. Whenever
// an event occurs on the serial port, a user-defined message will
// be sent to a user-defined window. It can then use the standard
// message dispatching to handle the event.
//
// Pros:
// -----
// - Easy to use
// - Fully ANSI and Unicode aware
// - Integrates easily in GUI applications and is intuitive to
// use for GUI application programmers
//
// Cons:
// -----
// - Uses a thread for each COM-port, which has been opened.
// - More overhead, due to thread switching and message queues.
// - Requires a window, but that's probably why you're using
// this class.
