However, if the IDD responds with a BUSY status or QUEUE FULL status due to its not being able to
receive the command that was issued, the UNIT ATTENTION condition is not cleared.
The above CHECK CONDITION status response that is the cause of the UNIT ATTENTION
condition hold can be prohibited by the specification of the CHANGE DEFINITION command.
