Right. I wasn't trying to imply otherwise. That's why Pavel Curtis
could use BSD curses as a basis for his pcurses.
It is only System V curses that was encumbered. And now it too is
available for inspection, if in a somewhat gray area for anyone with
commercial ambitions.

Agreed. I've seen no claim anywhere to the contrary.

Yes. This too is my understanding. terminfo is a better API (and
source format) than termcap, but I also surmise that better support for
deployment environments with large "fleets" of video terminals was also
seen by AT&T management as an enticing prospect for vendor lock-in.

Thank you for the confirmation. And for supplying some coaching all
those years ago--we're still enjoying the benefits today!
