When connecting an Arduino to USB, a port gets assigned. The Arduino connected to USB does give serial monitor output.
However I am unable to start an alternative serial monitor assigned to that port: "unable to open serial port" error.
What is wrong?

SOLVED. Sorry, so stupid of me: the Arduino serial monitor was open. When that is shut down the alternative monitor works.
