The RECEIVE DIAGNOSTIC RESULTS command transfers the diagnostic results indicated by the SEND DIAGNOSTIC command to the host. The RECEIVE DIAGNOSTC RESULT command must be issued following the SEND DIAGNOSTIC command. If not issued successively or if there is no data to be transferred, the command transfers no data and ends normally.
