BCB串口通讯源码示例程序。利用winapi函数，而非控件。

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.
