If the test ends due to mismatch between the sent data and received
data, the tested slave BHT beeps three times and displays the screen
as shown at left.
This sample screen shows that the received data is 255 although data
43 has been sent at 300 bps.
Selecting "5:DISPLAY" on the Hard Test menu calls up the test
pattern shown at left on the LCD and turns on the indicator LED in
green.
Each time the ENT key is pressed, the screen shifts to the next test
pattern. To return to the previous screen, press the BS key.
To stop this test while in progress, press the C key.
