Kill
On receiving the Kill command, in the Addressed mode only, the LRI2K compares the kill
code with the data contained in the request and reports whether the operation was
successful in the response. The Option_flag is supported. If the command is received in the
Non Addressed or the Selected mode, the LRI2K returns an error response.
During the comparison cycle equal to t
10%). Otherwise, the LRI2K may not match the kill code correctly. The t

interpret any other command.
