A bit late, but for the benefit of anyone else finding this:

Note that you also need to request read/write access to the device in your **.adef** file - or run unsandboxed.

See: [How to send and receive data using UART2 (RS232) interface - #3 by raf](http://forum.legato.io/t/how-to-send-and-receive-data-using-uart2-rs232-interface/2403/3)

> it would be nice to have this piece of information (i.e. that le\_tty is only available on 16.10 and onward) on [legato.io](http://legato.io), directly where le\_tty is documented.

Indeed!
