应用背景最近，认知无线电技术已经被提出作为未来的无线通信的关键技术利用动态频谱接入策略的通信。这提供了更灵活的方式利用无线基于固定频谱接入策略的频谱比传统无线电技术。认知无线电网络（CRNs），获得信道频谱空洞的信息，谈判的主用户和次之间用户对频谱分配、同步传输参数是铬介质访问的重要功能控制协议。在本文中，我们讨论了MAC层的基本职责和CRN的功能。基本上，我们专注于调查的最新进展，在铬麦克协议，以及它们的特点特点，优点和缺点。最后，我们提供了这些协议以表格形式的主要特点。关键技术认知无线电中的动态频谱接入网络仍处于起步阶段。许多重要的和复杂问题需要解决。在本文中，我们提供了一个调查，一些铬麦克协议并讨论了它们的主要工作原理结合自身特点。

C++ Builder 编的采用API函数多串口通讯源码,系本人在开发门禁控制器管理软件时曾编过的,希望对有这方面的要求的朋友有帮助-C++ Builder made the adoption of multi-function serial communications API source code, the Department of I in the development of Access Controller management software had been made, and they hope to have this requirement has to help a friend

RAS高级编程是一个RAS拨号程序高级开发，通过该程序不经能够实现电话拨号功能，还能实现如adsl、网通等拨号功能，还能够监控modem或者网卡的网络流量，绝对是一个值得读者学习的程序。-RAS is a high-level programming RAS Dial-up procedures advanced development, and the program can be achieved without a telephone dial-up function can be realized as adsl, Netcom, and other dial-up function, but also to monitor the modem or Ethernet network traffic is definitely a worthy readers learning process.
