Sentinel Definitions
The start and end sentinels values can individually be specified by commands. The default
settings are shown in the Table 4-4.
Note
Changing the value of any of the sentinels does not actually
change the encoded value on the magnetic track; it merely
represents the sentinel in a unique way to help distinguish
differently formatted tracks.
