  1. Rewind on Close special files write filemarks under certain conditions
     before rewinding.
  2. Retension on Open special files rewind tape on open only. Retensionning
     is not performed because there tape products automatically perform the
     retension operation when needed.
  3. Bytes per Inch options are ignored for the tape devices supported by this
     driver. The density selection is automatic.
  4. The rmt*.null file is a pseudo device similar to the /dev/null AIX special
     file. The ioctl call can be issued to this file without a real device
     attached to it, and the device driver will return a successfull completion.
     Read and write system calls will return the requested number of bytes.
     This file can be used for application development or debugging problems.
  5. The rmt*.smc file can be opened independently of the other tape special
     files. This special file applies to the IBM 3590. MagstarMP and 7332
     devices only.
