Dear SCO Customer,

Support Level Supplement (SLS) PTF3385, the SCSI Tape Target Driver 
Supplement, corrects a problem where an error created on a tape is not 
reported to the calling application.

SLS PTF3385 provides a new SCSI driver which allows errors on a tape 
to be reported to the calling application.

In order for the changes to take effect, a system reboot is required 
following installation of this SLS. 


Software Notes and Recommendations
----------------------------------

SLS PTF3385 should only be installed on these releases:

        SCO UnixWare Application Server Release 2.1.0
        SCO UnixWare Personal Edition Release 2.1.0


Testing of the modified software contained in this SLS has been 
conducted only to the extent necessary to confirm that it resolves 
the problem stated above.  Such testing consists of recreating the 
problem conditions (typically in an SCO test laboratory) and verifying 
that the problem no longer occurs.  No other testing of this software 
has been done.

Hardware Notes and Recommendations

This SLS is intended for i386, i486 and Pentium CPUs.
