I have never seen the other two items, but from windows point of view
the spec is probably the only thing that is useful.

I hope you have a lot of time and a good hold on sanity, because,
Brother, YOU ARE GOING TO NEED IT :-)
The DPMI is only partially supported under Windows3. If  you are
going to be running in 386 enhanced mode and are looking for fast
interrupt response, you probably also need the 10 interesting pages
out of the DDK documentation. But $xxx dollars is a lot for 10 pages.

The easiest way is probabaly to write all your buffer management and interrupt
handling as a TSR that is loaded before windows. Then do your IO checking via
a polling interface out of the windows VM. If you want to notify your
windows program of events in _nearly_ real time then down load one of the
public domain DOS interrupt lists and look at the new spec for the windows
bit of int 2F.
Good Luck.
