SYNOPSIS

DESCRIPTION

     The cartridge tape interface as found in the 7946 and 9144 products pro-
     vides a standard tape drive interface as described in mtio(4) with the
     following exceptions:

     1.   There is only one density.

     2.   Only the ``raw'' interface is supported.

     3.   The MTIOCTOP ioctl(2) is limited.  In particular, the command, MTFSR
          is not supported.

     4.   The MTIOCGET ioctl(2) is not supported.

     5.   The record size for read and write operations must be between 1K and
          64K inclusive.

     Special files rct0 through rct3 refer to rewind on close interfaces to
     drives 0 to 3.  Files rct4 through rct7 refer to no-rewind interfaces.
     Files rct8 through rct11 refer to streaming rewind on close interfaces.
     (Only 9144 type devices can stream.)  Lastly, rct12 through rct15 refer
     to streaming no-rewind interfaces.
