说明：  本程序可以用来进行TCP通信的调试，程序包含了TCP服务器和客户端两个部分。 TCP服务器可以在指定的端口进行监听，并同时最多处理100个连接。实时显示每个连接发送过来的数据，并且可以手工选择需要对哪个连接回送数据，或者是断开某个连接。 TCP客户端可以对某个IP（或者直接输入域名）的端口进行连接，实时显示已经连接的服务器发送的信息，可以手动输入需要发送到服务器的内容。 这个程序在对一些自己编写的服务器或者客户端的程序进行调试的时候比较有用。
(This procedure can be used for TCP communication debugging, the program includes a TCP server and client in two parts. TCP server port can be designated to monitor and at the same time deal with a maximum of 100 connections. Real-time display of each connection send data and can manually select which connections need to return data, or disconnect a connection. TCP client can be on a certain IP (or directly enter the domain name) to connect the port, real-time display has been connected to the server send the information, you can manually enter the need to send content to the server. This procedure in the preparation of some of their own server or client process more useful when debugging.)
