Subject: DPMI problems under Windows

I'm using the _go32_dpmi... functions in a program. Essentially, it's 
just an interface to a real-mode interrupt handler (a hardware 
interface). Under DOS, everything works fine; I also have a real-mode 
version of this program, written using TC++ 1.00, and it works fine too. 
However, when I run the program (DJGPP version) in a DOS box under 
Win3.1, it immediately bombs; not a segment violation or something of 
that sort, but it fails to access the real-mode hardware interrupt 
handler. I'm confused because I faithfully used all the appropriate 
_go32_dpmi... functions, and the program works fine under DOS...
