Rewind Packet
The Rewind command ($01) rewinds the tape to the BOT. If the immediate response bit is set, status is returned immediately, even though the controller is still busy rewinding. If a new command is sent before the controller is finished, a busy status may be sent to the MVME147, but the firmware performs an internal retry after the current command is done. If the immediate response bit is not set, status is not returned until the drive is finished.
The SCSI firmware table shows the rewind packet.
