Brainstorming uart.js functionalities

Thanks for the feedback!

As I understand it, UART.write/eval will create a connection (internally) and will then use that - so if you're writing to just a single device then that's all you need. You're prompted on the first call and after that it 'just works'.

Yes. My only issue is that I want to explicitly connect to the device before sending commands, to be sure the robot is ready and two way communication is established before starting the control loops.

I guess a work around is to trigger a connect by sending an empty UART.write('\n') and then use isConnected and getConnection. I will try and let you know how it goes!
