5-38 NCR 5977 2x20 Display Programming
Set Screen Save Walk
Format
1B 0A
Description
This command causes the visible display to walk right to left when the Screen Save
timer expires (five minutes). The characters on the 5976 display appear to walk across
the corresponding display row from right to left. The two lines in the 2x20 Display walk
in parallel completely off the left side of the dis¬play and then the two lines appear to
come back from the right. If the display is space filled, then no effect is perceived even
though the walking is taking place. The Screen Save Blank mode is the default mode
after power up.
Turn on Screen Save feature
Format 1B 0B
Description
This command causes the one of the screen save functions (Set Screen Save Blank or Set
Screen Save Walk) to activate immediately rather than waiting for the screen save timer
to expire. If the Disable Screen Save Option command is in effect when this command is
issued, it is canceled and the screen saver is enabled and activated immediately.
Disable Screen Save option
Format 1B 0C
Description
The firmware ceases to keep time for the screen save activity from the host software and
the display neither goes blank nor begins to walk due to inactivity from the host. This
command can be canceled by the Turn on Screen Save, Set Screen Save Blank, and Set
Screen Save Walk commands.
