The attribute itself is not necessarily programmedwith each new character code. Rather, each time a new character isreceived, the current setting of the character blink operator is adoptedas the working attribute for the new character. If a new character isreceived while character blink is enabled, the new character will blink.This makes it possible to have a display with both blinking and non‐blinking characters. The blink period is one second on and one secondoff. All characters that are blink enabled, blink at the same time. Theonly way to cause an existing character to start or stop blinking is to setup the character blink operator, locate the cursor to the correctcharacter, and resend the individual character code.
