Is it possible to tell what device a (gemdos) file handle is really pointed at? In particular, is it possible to tell if it's really pointed at the screen? In doing some IO hacking, I've come up with some stuff that really does want to be able to use Bcon<foo> when it can figure out that the thing being talked to is the keyboard/screen, but there appears to be no way to tell, other than blindly assuming. I'd like to find something modular and supported (Hah!), but will settle for anything. Hints anyone?
