menu, selection of transmit mode or maintenance mode is possible. If “display

6-6 Terminal Commands
This section describes the terminal commands used to display character strings or
graphics in accordance with instructions from the host, independently of the
screens registered in the NT20S.
Terminal commands designate screen attributes such as inversion, flashing, cur-
sor position and size of characters before the characters are displayed.
Once screen attributes are set, they remain effective for screen displays until they
are cancelled or other attributes are set.
In addition, continuous lines and circles can be drawn.

upgraded parts are re-displayed.
