AQDEV (ACQUIRE_DEVICE) -- Acquire control of a PBU device.
usage:  AQDEV pathname [-DB]


FORMAT

  AQDEV pathname [-DB]


  NOTE: This command is valid only if our General Purpose Input/Output
        (GPIO) software package is installed on your network.  See the
        GPIO Reference for details.

  AQDEV acquires control of a peripheral bus unit (PBU) device.  Actually, AQDEV
  creates a new Shell level in which the PBU device driver runs.    You  release
  the  device  by  closing  this  Shell level (i.e., type CTRL/Z).  See the GPIO
  Reference for more information on PBU devices.


ARGUMENTS

  pathname
  (required)         Specify the Device Descriptor File (DDF) for the peripheral
                     bus  unit  device  to be acquired.  You can create a DDF by
                     using the CRDDF (CREATE_DDF) command.


OPTIONS

  -DB                Specify debug mode.  Display addresses of the  mapped  DDF,
                     library, etc., along with any errors.


EXAMPLES

  $ aqdev /dev/my_dev
  Device 0 acquired.
  $ (Run your program using the device.)
  $ CTRL/Z
  *** EOF ***
  Device 0 released.
  $
