计算机接口技术系列 Visual C++串口通信技术与工程实践 在编译本章程序后，请将winio.dll、winio.vxd和winio.sys文件复制到可执行文件所在目录下, 否则WinIo库初始化函数initializeWinIO调用将会失败。-computer interface technology Series Visual C serial communications technology and engineering practice in compiling this chapter procedures, I would be grateful if winio.dll, winio.vxd winio.sys reproduction of documents and executable files to the directory, otherwise WinIo library initialization function initializeWinIO call will fail.

串行口是计算机一种常用的接口，具有连接线少，通讯简单，得到广泛的使用。常用的串口是RS-232-C接口(又称EIA RS-232-C)它是在1970年由美国电子工业协会(EIA)联合贝尔系统、调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是"数据终端设备(DTE)和数据通讯设备(DCE)之间串行二进制数据交换接口技术标准"该标准规定采用一个25个脚的DB25连接器，对连接器的每个引脚的信号内容加以规定，还对各种信号的电平加以规定。传输距离在码元畸变小于4%的情况下，传输电缆长度应为50英尺。 　　Linux操作系统从一开始就对串行口提供了很好的支持，本文就Linux下的串行口通讯编程进行简单的介绍.-computer serial port is a common interface, with connecting lines, simple communications, to be widely used. It is commonly used serial RS-232-C interface (also known as the EIA RS-232-C) it is in 1970 by the American Electronics Industry Association (EIA) Joint Bell System, a modem manufacturers and computer terminal manufacturers developed for serial communication standards. Its full title is "data terminal equipment (DTE) and data communications equipment (DCE) between serial binary data exchange interface technology standards," the use of a standard 25 feet to the DB25 connector, the connector pin of each signal content requirements, but also the right signal--

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.
