Subject: [TUHS] Anyone know what a LANTERN is?

There is a character in the terminfo/curses alternate character set,
ACS_LANTERN, which is mapped to "i" in the VT100 alternate grapical
character set. This character is, in fact, on a real VT100/VT220 (and
therefore in most modern terminal emulators that support the full ACS),
"VT" (in 'control character picture' format, along with HT FF CR LF
NL).
The ASCII mapping uses "#", and some CP437/etc mappings map it to the
double box drawing intersection character.
Was there ever a real 'lantern' character? The manpage mentions "some
characters from the AT&T 4410v1 added". What did it look like?
There's two references in the termcap manpages:
http://invisible-island.net/ncurses/man/terminfo.5.html
and
http://invisible-island.net/ncurses/man/curs_add_wch.3x.html
The second link mentions that the AT&T 4410 terminal added this glyph in the location
of the VT100 VT glyph. Apparently what it looked like is lost, unless someone finds a
detailed 4410 manual (or has a working one in the attic).
