The Interface Control mode page controls the selection ID used by the primary
interface (SCSI Parallel or Fibre Channel), as well as parameters of the Library serial
interface. A single copy of this page is maintained for all initiators. New CmdFwd and
Alerts will be in effect immediately after Mode Select. New Baud Rate, 2StopBits,
Next Selection ID, Target Initiated Bus Control, and Disable Wide Bus Mode will be
in effect the next reset or power cycle after Mode Select. This page persists across
power cycles.
Alerts are not implemented, so this field has a value of 0 and is not changeable.
