Terminal with Emulator

I was playing with the Terminal.println("hello world");

Am I right to expect that when E.setConsole("Terminal") or Terminal.setConsole(), it says the REPL is connected to this new 'serial port'.

So if my code has an error, which I would usually see on left in ide, eg. syntax error. The error should now be displayed on the emulator screen?? Cos I cannot see that behavior, but mb its cos the emulator kinda freezes once an error occur and I have to refresh page?

Also ... am I correct in expecting console.log to transfer to the connected serial??
