Set Display Screen or Column Brightness Level
Sets the display brightness level using a 3 byte command consisting of control code 30h, column
ID, and brightness level. Column ID code FFh sets all columns. Brightness levels range from 00h
(brightest) through 07h (dimmest). (Default is 00h)
Brightness levels must be set by columns rather than by
characters because of the construction of the vacuum
fluorescent tube.
Begin Blinking Character(s)
Sets the start of blinking character(s) or underbar(s) and the blink rate using a 2 byte command
consisting of control code 31h and blink code. Subsequent characters will blink until Control Code
32h is sent. (If a character is written at the current cursor location, that character will blink).
The "Underbar" and "Both" code sets apply only to 36X2–151–05240.

End Blinking Character(s)

blink).
If a blinking character is overwritten by a non–blinking character, or if the Erase Line command is
executed, the blink attribute is turned off.
