Stream devices arethose devices with peripheral device type codes 1h and 3h. Sequential-access (indicated by "tape" in theshorthand column) devices are those with peripheral device type code 01h. See 7.3.2 for peripheral devicetype code definitions.The application client shall use the RECEIVE COPY RESULTS with a RECEIVE DATA service action toretrieve data held for it by the copy manager (see 7.14.3).dpANS SCSI Primary Commands - 2 (SPC-2) 49
