Mode Select Command
The Mode Select command specifies options and parameters for a device.
StorageTek recommends the host system perform a Mode Sense command
before each Mode Select command to determine the current settings and to
avoid any unwanted alterations to other Mode Select fields.
The Mode Sense command determines which fields can be changed by the
Mode Select command and what the default values are for these fields.
The tape drives support both 6- and 10-byte commands.
