与各种不同的通信协议和帧结构。L2数据网络
各种L2数据网具有不同的通信协议与帧结构，其网络节点设备可以是各种类型的数据交换机（X.25、FR、Ethernet和ATM等分组交换机）；而L3数据网（IP网或internet）具有统一的TCP/IP通信协议和分组结构，全网采用统一格式的IP地址， 节点设备统一采用面向无连接的路由器。为便于理解，我们可以将L3数据网简单地理解为构建在L2数据网平台上的一个路由器网。-L2 data network with a variety of different communication protocol and frame structure, the network node device can be of various types of data switches (X.25, FR, Ethernet and ATM packet switches, etc.) and L3 data network (IP network or internet) have a unified TCP/IP communication protocol and packet structure, the whole network using a unified format for the IP address, node equipment reunification-oriented connectionless router. In order to facilitate understanding, we can L3 data network simply interpreted as a data network built on the L2 platform for a network router.

在VC++6.0中用MSComm控件编程，可以实现串口接收数据和发送数据，数据分别显示在接收框和发送框中。
如何建立工程：建立新文件夹，将文档用WINZIP解压后，双击 Scommtest.dsw 即可在VC6.0中打开工程文件。作者主页上有详细编程说明，每一步都列出来了，可以参考。-In VC++ 6.0 using MSComm control programming, you can realize the serial receive data and send data, data were displayed on the receiver box and sent box. How do I create a project: create a new folder, and will extract the files using WINZIP, double-click Scommtest.dsw can open in VC6.0 project file. Author home page has a detailed program description, list each step, and can refer to.
