Add an example to test the serial connection to the FX2 chip

mithro commented 7 years ago

RTS and CTS are for hardware flow control (request to send, clear to send IIRC).

The serial port also only transmits from the FX2 out.

You probably need to connect the ground pin too.

It isn't, or at least the firmware at no point expects input over serial from the host
