目前较为常用的串口有9针串口（DB9）和25针串口（DB25），通信距离较近时(<12m)，可以用电缆线直接连接标准RS232端口(RS422,RS485较远)，若距离较远，需附加调制解调器（MODEM）。最为简单且常用的是三线制接法，即地、接收数据和发送数据三脚相连，本文只涉及到最为基本的接法，且直接用RS232相连，以回答前段网友的咨询
There are currently more commonly used 9-pin serial port (DB9) and 25-pin serial port (DB25), while the short distance communication (< 12m), power cables can be connected directly to standard RS232 port (RS422, RS485 far), if the distance over far, the need to attach a modem (MODEM). The most simple and commonly used is a three-wire connection, that is, the receive data and send data tripod connected, this only involves the most basic connection, and directly connected with RS232 to answer the front-end consulting friends (2011-10-12, tcl/tk, 4657KB, 下载5次)
基于NS2仿真的AODV协议脚本文件. NS2(Network Simulation Version 2)是一种功能强大的网络模拟仿真器，它是用C++和OTCL两种语言完成的。C++语言编写协议执行模块，OTCL语言编写模拟任务。NS2主要针对有线局域网、无线局域网、Ad Hoc网络、卫星通信网、路由选择协议、组播路由协议等进行网络模拟仿真。
NS2-based simulation of AODV protocol script file. NS2 (Network Simulation Version 2) is a powerful network simulation device, which is the C++, and OTCL done in both languages. C++ language agreed to implement the module, OTCL language simulation tasks. NS2 targeted at wired LAN, wireless LAN, Ad Hoc networks, satellite communications network, routing protocol, multicast routing protocols such as the network simulation.
