Hi, I started a project for my school and I need to use node-red on a raspberry pi .  
The serial port works fine and I have no problem sending and receiving data with minicom or putty.  
But when I try using the serial node on node-red, only the output node works, I don't get any input.  
I should also say that I connected the tx and rx pin and like I said everything work just fine exept the input node.
