Anyway, there is some debate as to how best to determine if you're running
in an OS/2 DOS box. Myself, I prefer to check the DOS version; if the major
version is 20 or above, you're under OS/2 2.x.

Once you know you're in an OS/2 DOS box, calling interrupt 2F with AX set to
01680h will release the timeslice.

I have no idea if it works in OS/2 versions previous to 2.0; I do know it
works under Windows 3.x.
