Parameter Control Byte – DU, DS, TSD, ETC, TMC, and LP are collectively referred to as the Parameter
Control Byte.

saving parameters, this bit is always 1.
TSD
Target Save Disable. Since the tape drive does not
support saving parameters, this bit is always 1.
ETC
Enable Threshold Comparison. The tape drive does not
support Threshold Checking on this page. This bit is
always 0.

Threshold Met Criteria. This bit is always 0.
LP
List Parameter. This bit is always 0 since the tape drive
treats the parameter codes as data counters.
