Description
Key detection error/keyboard buffer overflow (if sets 2 or 3 scan
codes are enabled).
ABKeyboard ID.
Self-test passed.
Echo -- Sent to Host after receiving "Echo" command from host.
Acknowledge (ACK).
Self-test failed.
Resend -- Host responds by retransmitting the last command
sent.
Key detection error/keyboard buffer overflow (if set 1 scan
codes are enabled).
Description
Reset -- This command causes the mouse to enter the RESET
mode and do an internal Self-Reset.
Resend -- Any time the mouse receives an invalid command, it
returns a resend command to the host system. The host sys-
tem, in turn, sends this command when it detects any error in
any transmission from the mouse. When the mouse receives
the resend command, it retransmits the last packet of data sent.
Set Default -- This command re-initializes all conditions to the
power-on default state.
Disable -- This command is used in the Stream mode to stop
transmissions initiated by the mouse. The mouse responds to all
other commands while disabled. If the mouse is in the Stream
mode, it must be disabled before sending it any command that
requires a response.
Enable -- This command is used in the Stream mode to begin
transmission.
Set sampling rate -- In the stream mode, this command sets the
sampling rate to the value indicated by byte XX (HEX)/sex.
Read device type -- This command always receives a response
of 0x00 from the mouse.
Set Remote mode -- Sets the mouse to Remote mode. Data val-
ues are reported on in response to a read data command.
Set Wrap mode -- Sets the mouse to Wrap mode. The mode
remains until 0xFF or 0xEC is received.
Reset Wrap mode -- The mouse returns to the previous mode of
operation after receiving this command.
