The Demo App displays available commands in a command tree, as shown above.
Single-click on a command to populate the center panel of the window with optional
settings relevant to the command (e.g., "Amount" and "Start EMV Additional Tags"
above). In some cases, text fields will appear, allowing you to enter custom values.
When you are ready to execute the command in question, double-click it in the
command tree. The command executes in real time and a data trace appears
automatically in the center and/or right-hand panels. (Use the Clear Logs button to
clear both panels.)
