Hi - thanks for posting up...

The TTY would almost certainly be different, but a command like echo 'a' > /dev/tty.usbmodem* would probably be fine.

I'm not sure about the code that you post though - is that for an Espruino board? When Espruino is connected by USB, data comes in on the USB object, so I'd imagine that the following:
```
USB.on('data', function (data) {
  state = !state;
  LED1.write(state);
});
```
is more likely to work. Maybe you had the code in there already, and it only started working when you moved the console away from USB with: Serial1.setConsole();?
