Here is a possible fix:

> - I you don’t have Portainer:  
> Login in the CC100 with SSH then go to elevated user by using the command `su -`  
> Then use the command `docker exec -ti --user root <containername> /bin/bash` to open the container console as root.
> - If you have Portainer, use it to log in the container console in root.
> - In the container console, go to the node-red data folder `cd /data/`
> - Execute the command `npm rebuild --build-from-source`
> 
> This will rebuild the serial node from source to the specific of the CC100 system.
