Hi, You could try taking a look at something like the wineasio code. Whilst this isn't a device driver as such, it does demonstrate how to marry the WINE and Linux worlds together (one way). http://sf.net/projects/wineasio (I'm only caretaking the project, really...) -- Peter chrislpnt wrote: >> First of all what are you trying to archive? > > The application's GUI uses Borland's VCL library so that it can't be easily ported natively. I have tested this part under Wine, though, and it runs fine. If all the I/O the application required was usual, Wine-supported stuff (file and network access, etc.) I would be done here and could use the same binary. However, some of the I/O has to come from a driver that is not supported in Wine. The hardware works perfectly under Linux but obviously has a different API than in Windows. So, I have two elements: > > - Windows GUI code running under Wine > - Linux drivers resp. modules supporting my hardware.

Certainly the cleanest way would be to write a device driver for Wine but I was wondering if there was an easier way to interface to the Linux host from a Windows application running under Wine. > > > > > >
