前段时间刚刚接触VC的串行通讯，在网上找到的了SerialPort类的使用方法，不过我想将这个类做在DLL中，然后在VB中做通讯界面调用。花了几天时间终于做完了...

实现RAS客户类拨号上网系统-achieve RAS dial-up Internet customers type system

Lonworks技术是美国Echelon公司于90年12月推出的一种现场总线技。LON（Local Operation Network）为局部操作网络，具有现场总线技术的一切特点。Lonworks分布式测控网络技术，它真正并彻底地贯彻了“分散控制、集中管理的控制思想，在国际和国内都得到越来越广泛的应用。更准确地说Lonworks技术有效地解决了集散控制系统的通讯难题。Lonworks技术符合IEEE- 1437和EIA-709标准。 这是一个Lontalk协议栈的C语言参考实现，包括一个参考文档。极具参考价值-Lonworks technology is the Echelon Corporation in the United States 90 years in December launched a fieldbus technology. LON (Local Operation Network) for local operation of networks, fieldbus technology has all the characteristics. Lonworks distributed monitoring and control network technology, it is truly and thoroughly implement the

单音信号的一些频率估计程序，最大似然方法,Pisarenko法等。-This site presents some Matlab (tm) code for estimation of the frequency of a single, constant tone in noise. While these methods may be extended to the multiharmonic and multi-tone cases, these programs do not include this extension.

FTP（File Transfer Protocol）是文件传输协议，它规定了在Internet网络上怎样传输文件，通常要由专门的FTP程序来具体实现。

OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.

用VC 6.0实现串行通信的三种方法 本文介绍了在Windows平台下串行通信的实现机制，讨论了根据不同的条件用 Visual C++ 设计串行通信程序的三种方法，并结合实际，实现对温度数据的接收监控。 -VC 6.0 of the three serial communication method is introduced in the Windows platform to achieve the serial communication mechanism discussed under different conditions using Visual C serial communication program design of the three methods, and the light of reality, the temperature monitoring data reception.
