UART.js improvements #6
Description
As per http://forum.espruino.com/conversations/362281/#comment15950235
- write/eval should be per-connection (so if using connections the user doesn't have to split the data up themselves)
- When I register a customconnection.on('data', ...) callback, it overwrites the on('data', ...) callback defined within UART.write
- Also, it'd be nice to implement promises like @benfoxall did with the Puck.js lib
- Could also add a WebRTC connection option to allow you to connect on your phone and then use UART.js on a different PC
