一个高效率高兼容的VC 串口代码，比使用控件效率提高很多。简单易用-CSerialEx- 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.
