// hoofdzender (ping) die wordt aangesloten op de seriele monitor. De andere //
// transceiver (pong) wordt enkel op de voedingsspanning aangesloten. Door nu //
// een `T` commando te geven zal ping de huidige tijd naar pong sturen. Pong //
// stuurt de ontvangen gegevens dan weer terug en ping laat zien hoe lang de //
