Modbus协议，串口读取short,ushort,int,char

基于UDP协议通信 实现电脑之间的字符通信 简单的聊天功能(character communication based on UDP )

本实验可用于不同操作系统间网络通信，使用最简单的使用套接字进行传输(It can connecte different system.)

C# ping工具 实例源码下载

VFP的相关代码demo，很好的东西,VFP的相关代码demo，很好的东西(very good demo code,very good demo code)

c#实现网络嗅探器

异步套接字编写的网络聊天室程序，根据孙鑫VC++深入详解的例子改写，使用Visual studio 2008 SP1在Unicode编码环境下编写，可以收发中文字符。(Asynchronous socket program written in Internet chat rooms, according to Sun Xin VC++ depth Detailed examples rewritten using Visual studio 2008 SP1 environment written in Unicode encoding, you can send and receive Chinese characters.)

说明：  非等节点的分段M次Newton插值,属于数值方法的内容,很好(The piecewise M-degree Newton interpolation of non-equal nodes, which belongs to the numerical method, is very good.)

简易TCP通讯服务器端，QosClt为客户端。多个客户端间的通讯需要基于服务器，即通过服务器转发。(Simple TCP communication server, QosClt for the client. Communication between multiple clients need a server-based, that is transmitted through the server.)

说明：  本程序是window平台下，使用virtual C++编写文件下载程序，使用了Http协议(This program is a window platform, use the virtual C++ writing the file download process, using Http protocol)

利用哈希运算产生服务端和客户端的通信密钥( Produces the service end and the customer end correspondence key using the Hasche operation )
