Your loop is running at about 100ms.  So unless you can change that value in that time, of course the control will be read multiple times and the command performed several times.

1. You should move the serial port initialization to before the loop and the closing of the port to after the loop.

2. Have a button for performing your action.  You can then use an Event Structure to react to the button's value change and therefore perform a single action.
