Abstract:
A method of communication between a plurality devices connected by a SCSI bus, the method comprising the steps of:sending a signal on the SCSI bus from a first device to a second device indicating a request to initiate in-band but out of SCSI protocol communication between the first device and the second device; receiving from the SCSI bus at the second device the signal and transitioning the second device into an idle state wherein the second device does not modify or relay any signal on the SCSI bus; sending on the SCSI bus a clock signal from the first device to the second device; receiving from the bus at the second device the clock signal and transitioning the second device into an active state upon receipt of a finite number of clock edges; sending data on the SCSI bus from the second device synchronously with the clock signal; and receiving the data from the SCSI bus at the first device.
