What happens?

I get an error msg in the debug window but no msg from the status node. Also no msg from catch node. So in this case i get no information and cannot pull further actions.

What do you expect to happen?

A msg "Not connected" from the status node, so i can send an email, telegram ...

Node-RED v3.1.9, no fix yet

hardillb commented 4 months ago

@softy2k @samyakdoshi5 the node-red version is irrelevant.

Please feel free to submit a pull request against the node-red-node-serial node to implement the behaviour if you have a need for it

@hardillb I don't know what a pull request is, or how to do that :(

I'm new, and I wanted to make a project that requires me to display a popup when the serial port is disconnected.
