找芯片datasheet的工具，很好用。以后不用再跟供货商拿了

利用vc6.0 创建了mfc工程，实现了一个串口程序，是自己根据网上的代码，加上自己添加的代码，适合初学者。-Use of vc6.0 created mfc project implements a serial port program their own code under the web, plus add their own code, suitable for beginners.

IOCP(I/O Completion Port,I/O完成端口)是性能最好的一种I/O模型。delhi下的IOCP实现，一些代码和测试。

This paper will discuss the design of an asynchronous FIFO,Asynchronous FIFOs are widely used in the computer networking industry to receive data at a particular frequency and transmit them at another frequency. An asynchronous FIFO has two different clocks: one for read and one for write.-Asynchrinous FIFO design

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.
