SCSI status responses	In the SCSI communication mode, a function is considered
	incomplete until a valid status response is received from the other
	end of the SCSI link. There are three valid SCSI status
	responses:

	Status Response	Code	Meaning

	Good Status	00H	The frame was successfully
			received and individual fields
			within the frame contained legal
			characters.

	Check Condition	02H	A special condition occurred. A
	Status		SCSI Request Sense command
			is required to obtain information
			about the cause of the condition.
			Some host adapters
			automatically perform a Request
			Sense command.

	Busy Status	08H	Target is unable to accept
			commands at the present time.
			Host should try again. The host
			should wait a minimum of 100
			milliseconds before trying again.

	NOTE: "H" in the list above indicates hexadecimal notation.
