"rst" format
Special files "rst" (rewind on close) and "nrst" (no rewind on close) are also
built and reside in the /dev directory. For example, if the SCSI target ID for
the drive is 4 and the drive is connected to the native SCSI bus, then "rst" will
be "rst4, rst12, rst20, and rst28" and nrst will be "nrst4, nrst12, nrst20, and
nrst28".
rst4 and nrst4 correspond to the 0x82 density mode (CT-IV, native
format)
rst12 and nrst12 correspond to the 0x83 density mode (CT-IV,
compressed format)
rst20 and nrst20 correspond to the 0x84 density mode (CT-IV, native
format)
rst28 and nrst28 correspond to the 0x85 density mode (CT-IV,
compressed format)
Where:
CT-IV = CompacTape IV Data Cartridge
