Serial Monitor stopped working

particle serial monitor COM[X] stopped working.

particle serial list
gives me
Found 1 device connected via serial:
COM9 - Electron

But when I run “>particle serial monitor COM9"
It give me
"Command parameters ‘COM9’ are not expected here”

Windows 10 OS

It use to work and I tried several devices and none work. Putty works, but it is a pain to start up every time.

Just try without the COM stated. particel serial monitor will search for the device (just as particle serial list does).

I don’t think Serial Monitor stopped working. It may just be more verbose now about unexpected, unsolicited parameters.

I think you need to use the --port option now, instead of just specifying the port.

particle serial monitor --port COM9
