Running the test application would typically produce this kind of output:

Administrator name set to /dr/dvn
Test point counter will be used
Test block length set to 6 bytes
Successfully connected dvn_test to /dr/dvn

B) Testing Point Interface
   Listing points available:
     Pnt: volumeLeft (real) = 15.384381
     Pnt: volumeRight (real) = 20.731223
     Pnt: meterLeft (real) = 0.000000
     Pnt: meterRight (real) = 3.125706
     Pnt: thumbwheel (bit) = 1
     Pnt: pushon_pushoff (bit) = 0
     Pnt: pushbutton (bit) = 0
     Pnt: sonalertFault (bit) = 0
     Pnt: counterFault (bit) = 0
     Pnt: Buttons (bit) = 0
     Pnt: DI-Byte (bit) = 1
     Pnt: GreenLight1 (bit) = 0
     Pnt: GreenLight2 (bit) = 0
     Pnt: RedLight1 (bit) = 0
     Pnt: RedLight2 (bit) = 0
     Pnt: RedLight3 (bit) = 0
     Pnt: RedLight4 (bit) = 0
     Pnt: sonalert (bit) = 0
     Pnt: counter (bit) = 0
     Pnt: DO-Byte (0) = 25B70000
     Pnt: SonCnt (bit) = 0
     Error: dingroup value not available
     Error: agroup value not available
     Error: doutgroup value not available
   Describing point counter: 
     Point counter: type 5, RW, addr: 0:2.8
     Maps to: device 0, buffer 0, offset: 2, bit: 8
   Activating counter
   Deactivating counter

C) Testing Block interface.
   Device 0 has 6 buffers with the following sizes:
      Buffer 0: 4096 bytes.
      Buffer 1: 4096 bytes.
      Buffer 2: 0 bytes.
      Buffer 3: 0 bytes.
      Buffer 4: 0 bytes.
      Buffer 5: 3 bytes.

   Buffer 0 has not defined any segments.
   Buffer 1 has not defined any segments.
   Buffer 2 has not defined any segments.
   Buffer 3 has not defined any segments.
   Buffer 4 has not defined any segments.
   Buffer 5 has not defined any segments.
   Reading input block: device 0, buffer 1, offset 0, length 6 bytes 
     |0000: B113 891A 0100 
   Reading output block: device 0, buffer 0, offset 0, length 6 bytes 
     |0000: 0000 0228 0000 
   Writing to output block: device 0, buffer 0, offset 0, length 6 bytes 
     incrementing word at block offset 0x00 in steps of 100)

(At this point the system prints outputs from +00100 6400 0228 0000 through +10100 7427 0228 0000.)

     cycling bit through byte at block byte offset 0x04.

(At this point the system prints outputs from 0001 0000 0228 0100 through 0100 0000 0228 0000.)

D) Testing Control & Status interface.
   Reading Status:
     CAN status: 0x9209
                 CAN_ONLINE
                 CAN_ACTIVITY
                 CAN_BUSPOWER
                 CAN_ONLINE125
                 CAN_SCANACTIVE
     CAN transmit counter:     56530
     CAN ACK error counter:    0
     CAN receive counter:      56528
     CAN error counter:        0
     CAN msgs lost counter:    0
     CAN RcvQ overrun counter: 0

     Client status:    ACTIVE
     Server status:    IDLE
     Device  2 status: SCANNED

E) Testing Direct interface: toggle test point.
   Toggle bit of counter at 0:0:2:8
