SIP体系架构讲义及消息交互演示

代码实现串口收发数据功能，正常通信，这是本人自己练习使用，亲测通过，画图按钮实现的就是绘制函数并自动保存绘制的图片的功能

前段时间刚刚接触VC的串行通讯，在网上找到的了SerialPort类的使用方法，不过我想将这个类做在DLL中，然后在VB中做通讯界面调用。花了几天时间终于做完了，将SerailPort类的DLL工程共享一下，-Some time ago just contact VC serial communication, the Internet found the use of the SerialPort class, but I would like to do this class in the DLL, and then in the VB to do communication interface call. Spent a few days was finally done, and will SerailPort class DLL project to share what,
