并口操作？ [英] Parallel port operations?

问题描述

在遥远的过去，有些应用程序可以直接访问主板并行端口（ISA）。该应用程序不适用于插头和插件。播放（PCI）并行端口。



如果您知道PCI并行端口的基地址是与原始ISA端口相同的寄存器吗？



我问过这个董事会制造商的问题（比如SIIG）他们拒绝回答。

我的尝试：



我使用VC ++版本5来生成应用程序。它不像串行端口那样提供并行端口操作。它只提供标准的打印机服务。

In the distant past there were applications that did direct access to the motherboard parallel ports (ISA). The application do not work with the plug & play (PCI) parallel ports.

If you know the base address of the PCI parallel ports are the registers the same as the original ISA ports?

I have asked this question of the board manufactures (like SIIG) and they refuse to answer.

What I have tried:

I use VC++ version 5 to generate applications. It does not provide parallel port operations like it does for the serial port. It only provides standard printer services.

推荐答案

真的是VC 5吗？对于哪个Windows版本？



由于Windows NT普通应用程序无法直接访问硬件。你总是需要一个驱动程序。



因为并行端口已经过时，很难找到仍在运行的例子。但这个网站可能是一个很好的起点： Jan Axelson的Lakeview Research [ ^ ]

Really VC 5? For which Windows version?

Since Windows NT normal applications have no direct access to hardware. You always need a driver.

Because parallel ports are outdated, it is difficult to find still working examples. But this site may be a good starting point: Jan Axelson's Lakeview Research[^]

由于某些原因，CodeProject是具有大量并行端口文章的资源： 搜索 - CodeProject [ ^ ]。

-SA

By some reasons, CodeProject is the resource with ridiculously high number of parallel port articles: Search — CodeProject[^].
