| 摘 要： | 在Windows 2000/XP/NT下,由于系统安全性的考虑,用户不能对底层I/O口进行直接访问.为了利用并口实现PC机与外部设备之间的数据通信,本文给出了一种利用WinIo函数库提供的虚拟驱动程序绕过系统的保护机制实现并口数据通信的方法.在分析并口硬件工作原理及其工作方式的基础上,通过硬件接口操作试验,最终给出了在应用程序中利用WinIo动态链接库中的函数实现并口通信的过程及实现代码.

| Abstract: | Because of security,the I/O ports can't be accessed directly in Windows 2000/XP/NT.To realize the communication between PC and peripheral equipments by parallel ports,this paper proposes an approach which circumvents Windows protection mechanisms using virtual X device provided by WinIo library.Based on the analyses of hardware principle and working modes of parallel ports,finally through interface experiment the process of operation,codes to realize communication in application program with functions in dy... |
