VB

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)

PLC程序，结合VB通信实现两轴运动带减速功能(PLC programming, communication with VB to achieve two-axis motion with deceleration )

串口调试程序源代码，本例作为学习串口编程具有很好的参照作用。(Serial debugger source code, in this case as a learning serial programming with a good reference to the role.)

485多机通讯的连接方式，主要有总线方式、星形方式等(connection of multi pc communication with 485)

Visual c++串口通信工程开发实例导航，该书采用C++编写，里面包含5个综合实例，适合有一定基础的C++人员学习(Visual c++ serial communication engineering development instance navigation, using c++, the book contains five examples of comprehensive, is suitable for the staff to learn c++ has certain foundation)

我的毕业设计，很简单但很实用，是串口通信的典型实例，还有界面图形的设计(I graduated from design, very simple but very practical, is a typical example of the serial communication interface graphic design)

支持电力规约645，376.1等相关规约的485代码，支持常用电表控制信令代码，(Support the power of the Statute 645,376.1 Statute 485 and other related code, support for common control signaling code meter,)

云台控制的C++详细源码，二次开发可以直接用。(The PTZ control C++ detailed source, secondary development can be directly used.)

给出了基于MFC的can232接口的调试程序(MFC-can232 given based debugger interface)

这个是非常流行的串口调试工具的VC++源代码，对于需要深入了解串口通信的朋友非常有帮助，需要的朋友可以看看。(This is a very popular tool for serial debug VC++ source code, the need for deeper understanding of serial communication very helpful friend, a friend in need can take a look at.)
