Hello,

First, many thanks for all the information and these nice DLLs on the site!

I'm developing an application that has to deal with legacy hardware connected to the LPT port on many more or less old Windows machines. The OS of these computers will probably be ranging from Windows 98 to XP, but Win 95 can still be lurking somewhere too.

I've found the Inpout32.dll to work well in all environments so far, but the problem is I can't figure out the addresses of the printer ports, and I definitely don't want to make the users enter the addresses manually. So, I discovered the HWInterface32B01.dll on this site and it seemed to solve all my problems so far. Unfortunately it reads just "0" for any function call I've tried on Windows 98. On XP it works perfectly. Is it just me or is there something wrong with the HWInterface32B01.dll?
