That might have been the one I originally made, back in the time of
DJGPP 1.09 or so, for the very first port of texinfo's "info.exe" to
DJGPP. I did it the 'quick-and-dirty' way, just making termcap run on
top of ANSI.SYS (or better NNANSI.{COM|SYS}, a formidable replacement
for MS's implementation...).

In the longer run, I doubt termcap (or terminfo, for essentially the
same reason) can be implemented to use direct video memory writes and
stuff, instead of an ANSI.SYS implementation. The main problem with
that would be that application do have the choice to query termcap
strings and print them on their own, without going through termcap at
all. That means we'ld need an ANSI.SYS implementation inside the libc,
checking and filtering all output to the console for those
<ESC>-sequences, or require an external ANSI.SYS being preloaded for
programs that use termcap.

I don't remember having seen any such port of termcap, since then.
Anyone else has? Please tell.
