Description

DECLL controls keyboard LEDs independently of any keyboard state. The use of LEDs for this purpose conflicts with their use as keyboard state indicators. DECKLHIM selects a mode of how the keyboard LEDs are to be used: as keyboard indicators; or host indicators. If host indicators is selected, then the DECLL sequence can be used to control the keyboard LEDs.

For DECLL to function, DECKLHIM must be set.
