Description: 程序主要是基于套接字（Socket）进行网络编程的，采用的是TCP协议，TCP协议是面向连接的且是全双工的，即两个主机上的进程（比如进程A、进程B），一旦建立好连接，那么数据就既可以由A流向B，也可以由B流向A。此程序采用的是完全点对点的模式进行连接，即每台主机即是服务器又是客户端，因为它需要进行端口的侦听，所以在连接的时候必须知道各主机的IP地址和端口号。有了对方的IP和端口后两主机就可以进行握手过程，确认连接成功后就可以进行网络对话了。-Program is mainly based on socket (Socket) for network programming, using the TCP protocol, TCP protocol is connection-oriented and is full duplex, that is, the process of the two hosts (such as process A, process B) Once established a good connection, the data flow for both the A B, can also flow from the B A. This procedure uses a fully connected point to point mode, each host is the server that is the client, because it requires the listening port, so when the connection must know the host' s IP address and port number . With the other two host IP and port can be carried out after the handshake process, confirm the connection to the network after a successful dialogue.

(3) Tested from 1200 to 19200 Baud(@ 16 & 20 Mhz)
The User gets a total time as specified by the User Cycles
in the table ( or from equations ). The user routine has to
exactly use up this amount of time. After this time the User
routine has to give up the control to the Operating System.
If less than 52 uS is used, then the user should wait in a
delay loop, until exactly 52 uS.-Comments :
