After enabling Settings->Systems->Remote Control, I can allow sending ur script over the communication ports.
Also, An icon on the top right of the screen appears that can be used to switch between local and remote control.
However, if it is switched to Remote Control, after rebooting, the remote control is not allowed despite seeing on the screen that remote control is working. So, I have to switch back to local control and once more to remote control to make it actually work.
This has been identified as a bug, and will be fixed in our next software release.
