  Device Counters EXA0:
               Value  Counter
               -----  -------
          4294967295  Seconds since last zeroed
            38731696  Data blocks received
            28378137  Multicast blocks received
             2621447  Receive failure
          4294967295  Bytes received
          3203299230  Multicast bytes received
                   1  Data overrun
            13771761  Data blocks sent
              672064  Multicast packets transmitted
              662415  Blocks sent, multiple collisions
              502863  Blocks sent, single collision
             1056303  Blocks sent, initially deferred
          1462759444  Bytes sent
            76562996  Multicast bytes transmitted
            40042529  Send failure
                   0  Collision detect check failure
                   0  Unrecognized frame destination
                   0  System buffer unavailable
                   0  User buffer unavailable

      This example creates and runs a command procedure, COUNT.COM,
      that displays device counters once every minute.
