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.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
