conio.h is a DOSism (invented by Borland, IIRC).  Don't expect to find
it on Unix systems.

I think Linux has an emulation of conio, somebody posted a URL here
some time ago.  I suggest to search the DJGPP archives at
http://www.delorie.com/djgpp/mail-archives/.

conio.h has almost nothing to do with interrupts.  Most conio
functions use direct access to the video memory, not interrupts.

Yes, for portability use curses (and PDCurses in DJGPP).

I don't believe NT will ever disallow direct access to the standard
VGA memory.  Too many programs will break if they do.
