2. During the test, a data string is output repeatedly approximately once every three seconds. The data is:
[Testing COMx: nn] where “x” is the COM port and “nn” is an incrementing value beginning at 1 and
continuing through 99 then starting over again. Each transmission increments this number by one.
3. Any data received during the serial test is displayed in the bottom part of the display to the right of the
“Receiving:” label. Control characters are not displayed in this mode.
4. If a jumper wire is placed between the transmit and the receive indicators (Figure 5-4) on the port being
tested, the same data string that is transmitted displays as the receiving field. This jumper can confirm
correction operation of both the transmit and receive circuitry of that COM port.
