Safety Update: for old coscom v1 and coscom v2 interface protocols
In the very old coscom v1 and coscom v2 interface protocols the command of a negative speed (e.g. -0.5 km/h) can lead to unwanted acceleration.
Do not send negative speed commands via RS232 interface when working with coscom v1 or coscom v2. Upgrade to coscom v3 or coscom v4 as soon as possible!
