I’m new with node red, and I need your help, please.
I have connected two devices in serial port mode to node-red, using the serial in node. Both were working perfectly, until 1 day ago one of them (a bar code reader) has stopped writing on the tag (the nodes write in dasboards text inputs).
I have tried reading the device in other reader (RealTerm program) and it displays the port is already open. Then, I reset my PC and tried RealTerm again, and the device writes perfectly in this program, so I have switched again to node-red, but the device still writes anything. In this moment I want to try again in RealTerm and it displays the port is open...
What's happening with the port? Thanks is advance
