Dear SCO Customer,

Support Level Supplement (SLS) ptf7058d, the SCO UnixWare 7 mccntl Supplement,
provides the following corrections and enhancement:

ptf7058c provides the following corrections and enhancement:

(1) mccntl -s was fixed, which previously reported back an incorrect
    number of storage slots when used with a tape library.

(2) A new argument is provided, -t, that enables the user to specify
    which tape drive to use on tape library devices that contain more
    than one drive.  The -t argument is used as follows:

                mccntl -t

    The first tape drive is 1. Subsequent tape drives are numbered
    consecutively.

(3) mccntl -e was fixed, which previously failed with an invalid drive
    address message. The reported error message is:

                ERROR: Invalid source element 241, valid range 1-8

ptf7058d only provides the new option of installing the ptf in quiet mode.
