The RS-232 test icon allows you to test serial communication from the serial port by
using the printer port as a return port. See
1. Disconnect the printer and RS-232 serial connections and connect a serial cable
between the analyzer's serial ports (from one serial port to the other).

Start test icon sends serial data out one serial port and reads the data on the other. If
the read data matches the sent data, the test passes.
