command will not be accepted when sent, and only the
status SENSE command will be returned (the status
SENSE command is also valid in error modes, and is
returned). Enter the CLEAR ERROR (41H) or CLEAR
(56H) commands to clear this mode.
Enter the CLEAR ERROR (41H) command to delete
numerical commands entered (transmitted) at the end of
