Eh?  Those are viddotex/teletext systems aren't they?

I thought the OP was talking about a character-based windowing and
form-handling library used by applications that ran under VAX/VMS on
vt200 terminals.  The vt200 wasn't a TV.  It was a character-based,
mostly-ANSI-escape-sequence, computer terminal connected via async
serial (RS-232 typically) to a mini/mainframe computer (a DEC VAX
running VMS in this context).
