Not all terminals have special boxing characters. If your terminal does not have them, hyphens (-) and vertical bars (|) are used instead. Using boxing characters, however, greatly improves the appearance of forms using table fields.

Command	Description	VT100 Example
ld	Initializes terminal to draw solid lines.	ld=\E)0
ls	Interprets subsequent characters for drawing solid lines.	ls=\016
le	Interprets subsequent characters as regular characters.	le=\017
qa through qk	Boxing characters; see the next table.

The table below describes the boxing characters qa through qk mentioned in the previous table:

Command	Description	VT100 Example
qa	Lower right corner of a box	qa=j
qb	Upper right corner of a box	qb=k
qc	Upper left corner of a box	qc=l
