Terminal Commands
This section describes the terminal commands used to display character
strings or graphics according to instructions from the host, independently of
the screens registered in the NT20.
Terminal commands designate screen attributes such as inversion, flashing,
cursor 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.
Clear Screen
Format
Description
Clears all text and graphics on the NT20 screen.
Reference:
Even if this command is used to clear a screen, the NT20 still displays the pre-
ceding screens.
After the display of number, text, lamps or touch switches is upgraded, only
the upgraded parts are re-displayed.
Character Specify Size
Format
Description
Specifies if 1-byte alphanumeric characters sent subsequently are displayed
as normal characters or 1/2-size characters.
Reference:
The character string is specified with the Specify Displayed Characters Com-
mand (refer to
Specify Displayed Characters
). Both normal characters and 1/
2-size characters are enlarged as specified by the Specify Character Enlarge-
ment Command (refer to
Specify Character Enlargement
below).
The character size specified with this command remains valid until the screen
display is switched or another character size is specified with the command.
The default character size is normal characters.
