       cdi_set_compression - set or unset compression on a tape device

       cdi_set_compression -f  device [ -v ] [ -c {Yes | y | 1 | No | n | 0} ]
			   [ -t { s | t | g | n | m | i } ]

       The cdi_set_compression program sets or unsets compression  on  a  tape
       device.	 This program is functional only on NT.	 On all other OS plat‐
       forms, the program does nothing but returns SUCCESS.

       -f     device
	    Specifies the device to perform the SCSI command  operation.   The
	    -f option is a required option.

       -c     [Yes | y | 1 | No | n | 0]
	    Specify  whether  to  set or unset compression on the tape device.
	    Use Yes , y , or 1 to set compression on the tape device.  Use  No
	    ,  n  , or 0 to unset compression on the tape device.  The default
	    is to unset compression on a tape device.

       -t     Use the -t option to specify the method of tape functions to use
	      to set/unset device compression.	If the -t option is not speci‐
	      fied, the default method is to  use  the	OS  tape  driver  SCSI
	      passthrough  functions.	Please refer to the libcdi (8) manpage
	      for the complete list of access methods currently	 supported  by
	      the cdi_set_compression program.

       -v     Run the program in verbose mode.	This option will print out the
	      version number of the CDI library used by the program.

       Sample output from the cdi_set_compression program:

     % cdi_set_compression -f /dev/rmt/2cbn -c 1

      CDI_SET_COMPRESSION 0 successful.

     % cdi_set_compression -f /dev/rmt/0cbn -c No

      CDI_SET_COMPRESSION 0 successful.
