本人多年前做的一个控制系统项目的程序,连接串口可以和仿真通信,用到了绘图的多个方面，是控制系统上位机编程的很好范例-years ago, I do a project control system procedures, and can connect serial communications simulation, the use of graphics in many areas of PC Control System Programming a good example

实现RS232串口通信，绘制从串口采集到的数据波形图-Serial communication, the data collected to draw waveforms
