Is bypassing the DOS calls a good idea?  How do you get a handle from
CreateFile that can be used in various DOS calls, such as 214400?

The handle you return must be a valid DOS handle, otherwise lots of
things will subtly break.

What SFT do you have in mind?  If that's the SFT for the DOS box, I'm
not even sure NTVDM creates it.
