issues interfacing with OS X

I am having some issues interfacing with OS X. I follow the instructions from http://www.espruino.com/Interfacing but when I type echo "LED1.set()" > /dev/ttyACM0 – obviously with the right tty – it doesn't do anything. It doesn't return to the command line and I can't use the Web IDE to connect until I cancel the action. I am able to connect using screen though.

I'll need to look at this - unless someone else gets there first ;)

I imagine it's something that needs to be set up with stty. On Raspberry Pi I've used:

stty -F /dev/ttyAMA0 9600 -parenb -parodd cs8 hupcl -cstopb cread clocal -crtscts ignbrk raw min 0 time 5

but there may be different settings needed on Mac. If I'm honest I'm not 100% sure on this, but it's probably just a matter of turning flow control off.

Ha, your answer didn't really help me (as the -F flag is not available for example), but a quick look through /dev/ showed another device /dev/cu.usbmodem1411 while I normally connect to `/dev/tty.usbmodem1411. And this one works like a charm.

Maybe best to double check this, but it thus seems that all you need to do on OS X is to write to cu instead of tty. Not surprising though that it is different from Linux/Raspberry, given that it is BSD based instead of Linux based.

Strange... Thanks for the info, I'll give it a try and update the docs.

Glad you got it going - that'll be a huge help for Mac users looking to do some simple hardware stuff.

The mystery deepens ... the devices connect to Bluetooth just fine and I can access them using screen. However, piping to either tty or cu causes them to disconnect from Bluetooth ...
