There is a bug in your program.  The interrupt you are using expects a 
string in DS:DX, but the DPMI specification clearly states you can't expect
this to work, since DS will be undefined in the real mode reflection.

It works under Win 95, Win 3.1, and some other DPMI providers because they
also provide a built in DOS extender which copies the string for you to
a real mode buffer, then assigns DS:DX to that buffer.
