Description
Turns on/off LEDs -- Keyboard replies with ACK (FA) and waits
for another byte to be sent. Next byte sent determines the state
of the LEDs. (Bits 0-2 correspond to LEDs 1,2,3. Bits 3-7 should
always be 0.)
Echo -- Keyboard should respond with Echo (EE).
Set Scan Code Set -- Responds with ACK (FA) and waits for
another byte to be sent. Next byte sent will be either 01, 02, or
03 (corresponding to scan code sets 1, 2, and 3.) If 00 is sent
(instead of 01, 02, or 03), keyboard will respond with ACK (FA),
followed by the current scan code set (again, 01, 02, or 03).
Get ID -- Responds with ACK (FA), followed by an ID (A3, AB).
This also enables scanning.
Set repeat rate -- Keyboard replies with ACK (FA) and waits for
another byte to be sent. Next byte sent will determine the type of
automatic repeat rate for the keyboard. After this byte is sent,
keyboard responds with another ACK (FA).
Enable keyboard -- Clear the buffer and start scanning for data;
replies with ACK (FA).
Disable keyboard -- Disables scanning and replies with ACK
(FA). Does not affect indicator LEDs.
Restore default values. Does not affect indicator LEDs.
Set all keys typematic. Responds with ACK (FA).
Set all keys make/break. Responds with ACK (FA).
Set all keys make. Responds with ACK (FA).
Set all keys typematic/make/break. Responds with ACK (FA).
Set key type typematic.
Set key type make/break.
Set key type make.
Resend -- Keyboard responds by retransmitting the last
command it sent.
Reset -- Resets the keyboard.
