Hi,  
What works:  
I have a card connected to my PC via USB. In my dashboard I display the data transmitted by the serial node. That's OK. Now I change the card, the COM port changes and I have to enter the config to select the new COM that I find with the auto-detection magnifying glass.  
 ![liste deroulante com](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/2/4/243989cf39ceea95e34f8acf9cc6ee863432622d.jpeg)

It's restrictive!

What I would like:  
is to be able to launch an auto-detection of the COM ports from the Dashboard, therefore send a message to a serial node that would output the list of available COMs. Thus I could select the correct COM port attached to my device in a drop-down list.  
I don't see anything in this sense in the doc. Is it possible?  
Thanks
