API串口读写模块 这是用VB编的通过API来对串口进行读写操作

Rayleigh fading channel是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的“衰落”，并且其包络服从瑞利分布。

摘要 TCP 软件一般位于操作系统的核心，这种情况给TCP 的研究和调试带来了很大的困难。 在Sun Solaris 平台上，我们使用系统提供的DLPI 接口和有关多线程的系统调用，构建了一 个TCP 调试系统，简化了调试过程。 关键字 TCP，调试系统，DLPI，多线程-Abstract TCP software at the core of the operating system. This situation TCP research and testing has led to great difficulties. Sun Solaris platform, We use the system to provide the interface and the TCP multithreaded system calls, built a TCP debugging system, simplifies the debugging process. Keywords TCP, debugging system, Solaris, multithreading

Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite. -Transporting DNP V3.00 over Local and Wide Area Network. 1 Overview 1.1 Purpose DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485).
