FreeBSD?

Chrome serial

Is his version of Chrome up to date? If it is then I think this could be a udev issue - I don't know enough about FreeBSD (or anything, actually) but I think on Linux chrome checks udev to figure out what it should display and what it shouldn't.

Not sure if FreeBSD has udev or not, but you might be able to write a udev rule that sets the Espruino to be the correct class of device. udev rule for espruino on linux here if you need to see how to match it.

If you figure it out, please let me know - I can update the docs.

if you were to type hello, hell would appear. If you then typed !, the o would appear, but not the !.

Have you updated it to 1v80? This was a bug that got fixed in the most recent version :)
