[Bochs-developers] bidirectional parport?

[Brian G. <bri...@ya...>]

Hi all,

After reading throught the code for the parallel port, I noticed that it is
unidirectional.  (The file it opens used "wb" as it's open flags)

Is there a specific reason that it was not made bidirectional?  If I were to
take the existing parallel port module, and make it bidirectional, is there
anything I should know?  Will it be relatively straight forward?

In case you want to know why I want it, I am using Bochs to run RTAI Linux, a
real-time OS, for educational purposes.  I want to develop an example in the
guest, that communicates to simulated hardware via the parallel port in the
host.  Bi-directiality is needed.

Thanks,
Brian
