REPL:
Adafruit CircuitPython 3.0.1 on 2018-08-21; ESP module with ESP8266
Press any key to enter the REPL. Use CTRL-D to soft reset.
>>>

    Ctrl-A on a blank line will enter raw REPL mode. This is like a permanent paste mode, except that characters are not echoed back.
    Ctrl-B on a blank like goes to normal REPL mode.
    Ctrl-C cancels any input, or interrupts the currently running code.
    Ctrl-D on a blank line will do a soft reset.
    ctrl-E will special paste mode

    Note that ctrl-A and ctrl-D do not work with WebREPL.
