Chapter 4: Programming Set Up |
Turn On Screen Save
Format: 1B 0B
Description: This command causes 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 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.
Enable Character Blink
Format: 1B 0D
Description: The blink attribute is the only modifier which is supported for the display character positions. Each time a new character is received, the current setting of the character blink operator is adopted as the working attribute for the new character. If a new character is received while character blink is enabled, the new character blinks. This makes it possible to have a display with both blinking and non‐blinking characters. For the VFD, the blink period is 1 second on and 1 second off. For the LCD, the blink period is .5 second on and .5 second off. All characters that are blink enabled blink at the same time. The only way to cause an existing character to start or stop blinking is to set up the character blink operator, move the cursor to the correct character, and resend the individual character code.
