实现函数发生器产生的波形能够在电脑显示器上显示。函数发生器通过GPIB卡与电脑连接并传输数据，电脑上通过LABVIEW软件环境完成与GPIB卡的数据通信。在LABVIEW环境下完成了对虚拟仪器前面板以及后台程序框图的设计与编程。在LABVIEW开发环境下，实现对GPIB控制时，采用VISA模块驱动的方法进行编程。设计结果在LABVIEW环境下的虚拟示波器能够实现示波器的功能，能够显示函数发生器所产生的任意波形。- achieve the waveform can be displayed on the screen of the computer which send out by the function generator. The function generator connect to computer through a GPIB card and transfer data. Labview can be communicated with GPIB card and save data on computer. The virtual instrument front panel design and background process diagram programming can achieved under Labview software environment. The realization of GPIB control, using VISA module-driven approach to program in Labview. The result of the design is that the virtual oscilloscope is able to complete the Real oscilloscope function in Labview.

是关于美兰日兰电源通信规约的串口通信程序，功能是把电源监控器的采集数据上送到规约前置机中。-GOLD comunication rule

使用说明： 系统要求：WIN9X/ME/NT/2000 VC++6.0 且安装了VC ACTIVEX控件（在VC6安装时选上） 免费 简介：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。-Usage: System Requirements: WIN9X/ME/NT/2000 VC++ 6.0 and installed VC ACTIVEX controls (in VC6 installation selected) Free Introduction: In VC++ 6.0 using MSComm control programming can be achieved Serial receive data and send data, data were displayed on the receiver box and sent box.

自己使用VB编写的串口通信程序，1号和2号。将两个COM口用串口线连接，就可以运行这两个程序了。实现的功能：1号程序随机发送两个数字，2号程序接收并进行计算，然后发回1号机，1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.

VC编程实现的串口通信，界面简洁，实现基本的串口通信的作用。-VC programming of serial communication, the interface simple to achieve a basic serial communication role.

delphi编写的com程序,自己可以添加功能,可用做串口调试-com prepared by the procedures, they can add functionality and can be used for debugging serial
