My system has suddenly stopped connecting to Serial under a Windows 10 for debugging purposes.
It was working until a couple of days ago.
I can use Particle serial from a command window.
Windows Device Manager shows the device on a COM channel (3 devices have shown up on COM3, 4, and 6 respectively) and the same channel is shown on the serial terminal.
DEV IDE Serial terminal shows the COM6 device but it will not connect. the same behaviour is seen on 3 different Photons.
Have re-installed cli without any change in behaviour.
Any ideas would be most welcome.
