is there a way to detect my PICO is connected to console/Web IDE?

Still experimenting with "the bare PICO" and reached some standalone scenario:
I plan to modify the http://www.espruino.com/Single+Button+Combination+Lock
to automatically run as soon as it got power (save(), onInit ...).

The original code uses console.log to show status which I like to keep when managable.
Is there a way to detect that there is no console attached so I can switch to alternative (LED signals)?

TIA, Uli

You can check process.env.CONSOLE=="USB" - this will detect if Espruino has a connection to your PC (eg. it appears as a COM port).

However it has no way to know if you have an application running on the PC that is looking at what it is printing!

@gordon: Thanks for your info; so I have not overlooked a useable functionality in the references.
