There is a solution for calling the IN and OUT instructions under Win32:  
Inpout32.dll

http://www.logix4u.net/inpout32.htm

It works seamless with all versions of windows (98/NT/2000/XP).

I have succesfully used it in a C++ program of mine. (Don't ask _me_ how  
to use it in D, I'm still a rookie in the D world... ;) )
