Field Name

Description

DBR

Data Buffer Recovery. Not supported, must be 0.

BIS

Block Identifiers Supported. This field is supported. Set to 1.

RSmk

Report Setmark. Not supported, must be 0.

AVC

Automatic Velocity Control. Not supported; must be 0.

SOCF

Stop on Consecutive Filemarks. Not supported; must be 0.

RBO

Recover Buffer Order. Not supported; must be 0.

REW

Report Early Warning. Not supported; must be 0 (do not report Early

 

Warning EOM on READ).

Gap Size

Not used; must be 0.

EOD Defined

End-of-Data Defined. This field must be set to 00h.

EEG

Enable End-of-Data Generation. Set to 1. This field indicates that the drive

 

will generate an EOD. The drive generates an EOD mark before any change

 

of direction following a WRITE-type operation. This bit is ignored, however,

 

on MODE SELECT.

SEW

Synchronize at Early Warning. Must be set to 1.

Buffer Size at Early

Not supported; must be 0.

Warning

 

SEW

Select Data

Compression

Algorithm

Synchronize at Early Warning. Must be set to 1.

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.
