The IBM document
Item 9VRCJ Document ID Q519417
Title: 901217 HOWTO AIX: MODIFYING TERMINFO DESCRIPTIONS FOR
OEM TERMINALS FOR USE WITH INFOEXPLORER
gives a little information on the box1 terminfo field. It says:
box1=LhRvrl
where: L = character user to draw upper left corner
h = character used to draw horizontal lines
R = character used to draw upper right corner
v = character used to draw vertical lines
r = character used to draw lower right corner
l = character used to draw lower left corner
As an example,
box1+-+|++
draws boxes with `+' at the corners, `-' in horizontal lines and `|' in
vertical lines.
Box1 is the only terminfo field this document describes. It refers the
reader to "the TERMINFO documentation in the Files Reference Manual,"
but I think that's what infoexplorer finds when you do a search on "box1".
