串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上 经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合 会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～ 20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性 都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为 一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standard through the use and development, now has several. However, in the RS-232 standard on the basis of an improved formed. So to the main RS-232C for discussion. RS-323C standard is the United States EIA (Electronics Industry Association) and BELL, such as the development of the company in 1969 with the publication of the communication protocol. It is suitable for data transfer rate at 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as signal line features, electrical characteristics have been clearly defined. Because of prevailing production and equipment manufacturers have standard RS-232C compatible communications equipment, t

实际是一个网络编程中模拟读写串口的程序.不过是创建了一个文件,把文件当作串口进行操作-is actually a simulation of network programming literacy Serial procedures. But is the creation of a paper document to operate as a serial

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.
