Parameters

   o  robot_name - The name of the robot device to be opened. On
      Digital UNIX, if the leading character of the name is not a
      slash (/), /dev/ will be prepended to the name.

   o  inport - This is the address of the character string
      containing a zero based address of the port to be readied.

   o  log_info - This is a character array that should be at least
      MRD_MAX_LOG_STRING in length. If this function fails as the
      result of a SCSI error, this will be filled with the formatted
      request sense data. If this function fails as the result
      of an operating system error, the operating system message
      particular to the error will be copied into the array.
