Compression
Algorithm When set to 1, enables data compression.
When 0, disables data compression.
The setting on the front panel of the tape drive overrides any setting of
MODE SELECT, but no error will result. If the setting is returned to the
automatic mode on the front panel of the tape drive, the value from the last
MODE SELECT command determines whether compression is enabled or
disabled.
