并口测试程序，是我2003年在上海市激光机技术研究所工作期间编写的，主要目的是测试通过并口控制声光调制器的脉宽和频率已达到控制激光标刻机的激光束状态的目的，因为不同脉宽和频率的激光束在物体表面上标刻出来的效果是不同的。当然，该测试程序还可用于其他需要并口输出不同脉宽或频率的方波的应用场合。

该程序已应用了WinIO程序，所以WinNT下也可以控制并口。

flyskywhy@gmail.com-Parallel testing procedures, is my 2003 in Shanghai Laser Technology Research Institute, prepared during the work, the main objective was to test the parallel port control through acousto-optic modulator of the pulse width and frequency has reached the control of laser marking machine laser beam state The purpose, as different pulse width and frequency of the laser beam at the object surface, marking out the effect is different. Of course, the test procedure can also be used for other needs of different parallel output of the square wave pulse width or frequency of applications. The procedure has been applied WinIO proceedings, it can also be controlled under WinNT parallel. Lee flyskywhy@gmail.com
