Good day  
I would like to know if I can autocomplete the form with information that comes to me from the serial port.  
I need that what the serial port generates be automatically filled in the "Internal identification (cafrilosa)" section.  
I appreciate your help.

Hi @Jhontan14, if you select "Text option" on Type on Form Elements, on your "form node" you can set "msg.payload.interna" property into flow variable, i'll show you:  
 ![s1](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/7/07997837de3a2857282626513bb991342bfb72d5.png)  
Then you can store/save you value string from SERIAL to a flow variable, then set the property "msg.payload.interna" with a change node:

I simulated serial input with a inject node:

this is the code:

```auto
