I had a similar problem, I could use int19 from a program and it would work,
but if I used it from an interupt it would sometimes hang. I suspected this
was because int19 assumes a stack is set up, then reloads dos. So if the
dos stack is the one being used, a crash occures. I ended up using a
long jump to FFFF:0.
