并行端口I/O WinXP [英] Paralell port I/O WinXP

问题描述

使用inpout32.dll，我可以读写端口寄存器，但是寄存器内容未在数据线D0-D7上反映(再现).我非常确定这不是软件问题，除非我未能启用某些功能.控制中是否需要设置一些位，以使寄存器数据可以在数据线上观察到.我在这里想念什么?感谢您的任何建议. RTFM不适合使用，因为我已经阅读了所有可以找到的内容.

感谢solutions.s的链接.我已经进行了详尽的研究，非常有用.

Using inpout32.dll I can read and write to the port registers however the register contents are not reflected (reproduced) on the data lines D0-D7. I''m quite sure it is not software issue unless I have failed to enable something. Is there some bit to set in control to enable the register data to be observed on the data lines. What am I missing here? Thanks for any suggestions. RTFM is not appropriate as I have read all I can find.
