The only check made when this page is sent in Mode Select data is Parameter List.
Changeable parameters:
Write Delay This field can be modified by a MODE SELECT command, and this change will be
Time reflected in a subsequent MODE SENSE command. However the actual value used as the delay time will remain as zero, and so the data in the buffer will never be flushed. The default value is zero.
0 The drive will never flush buffered data to tape as a result of a
>0 The time in 100 ms increments that the drive should wait with unwritten data in the buffer and no activity on the interface before forcing data to tape. The delay is timed from the completion of the preceding Write or Write Filemarks command.
