: The drivers for the Seagate Travan tape drive are supplied by SCO as part
: of the system installation. I'm able to use the tape drive normally with no
: problem. However, I'm unable to do a "tape getcomp" or "tape setcomp" to
: review or set data compression methods.
: 
: I have one system of 15 where the system exceeds 5 gig of space, and won't
: fit on an uncompressed 4-gig tape. If I could turn on compression, that
: system would easily fit on the tape.
: 
: Does anyone know how to turn on the compression for a Travan tape drive
: (ATAPI if that matters) under SCO 5.0.5a?

   ^^^^^ it matters greatly.

: Thanks for any pointers.

I'm afraid you are under a misconception.

There is currently NO such thing as an ATAPI drive with built-in
hardware compression.

Seagate offers the following Travan models...

-- 4/8GB --                             -- 10/20GB --

      /  Hornet 8                             /  Hornet 20
ATAPI                                   ATAPI 
      \  TapeStor Travan 8                    \  TapeStor Travan 20

       / Hornet 8                              / Hornet 20
      /  Hornet NS8                           /  Hornet NS20
SCSI                                    SCSI
      \  TapeStor Travan NS8                  \  TapeStor Travan NS20
       \ TapeStor Travan 8                     \ TapeStor Travan 20

Of those models, only the "NS" series has hardware compression, and
those models are only available in the SCSI interface.

Seagate, like other vendors, ALWAYS doubles the raw capacity of the
tape drive when reporting it. They ASSUME in the case of tape drives
that don't do hardware compression, that you'll be using backup software
that does software compression.
