VC_MFC-Sample1
Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置
串口属性的实例.
在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口
进行通信.串口通信方便易行,应用广泛.
一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是
半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点.
每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正
确的命令后作出应答.
(Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

模仿超级终端风格的RS232串口调试工具
这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。
里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style
This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load.
Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)
