Hello,

I have an windows 16 application written in visual c 1.52, the application works perfect on windows 95. On windows XP there are 2 problems - ports and memory access.
I was able to fix both with direct i\o (http://www.direct-io.com/) but the application is also using the serial port (command opencomm) and the direct io software conflicts with the api of the serial port, My question is: is there another solution to open both ports and memory? I know that porttalk will open ports and it works with the serial port but it doesnt open memory access.

Thanks.

I recall there was a program called UserPort, though I'm not sure where to find it at the moment. Perhaps that will work?

Found User port and it seems like its only enabling port access which porttalk does perfectly, I also need MMIO (Memory mapped io) access

Google for WinIO. It supports port-IO and memory-mapped IO.

Off-topic but I wanted to tell kjliew that he is awesome. 😀

WinIO is a dll library that is possible to use with Visual C 6 and up. I have visual c 1.52 and I'm looking for something similar to the way porttalk and directIO is working.

Out of curiosity, what type of program is it? Typically Windows programs treat serial port I/O like a file and don't require direct hardware access.

It does treat it like a file - it uses the opencomm function which is similar to the openfile in vc 6+. but direct io is conflicting with the command.
