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.
