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".
