VB 通讯编程方面的例子程序： 获取主机名和IP地址

A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;

在VC++6.0中用MSComm控件编程，可以实现串口接收数据和发送数据，数据分别显示在接收框和发送框中。 如何建立工程：建立新文件夹，将文档用WINZIP解压后，双击 Scommtest.dsw 即可在VC6.0中打开工程文件。作者主页上有详细编程说明，每一步都列出来了，可以参考。-In VC++ 6.0 using MSComm control programming, you can realize the serial receive data and send data, data were displayed on the receiver box and sent box. How do I create a project: create a new folder, and will extract the files using WINZIP, double-click Scommtest.dsw can open in VC6.0 project file. Author home page has a detailed program description, list each step, and can refer to.
