I'm trying out computer to computer serial communication using 2 Arduino Unos (both connected to different computers). Right now, I use the Software Serial library, which redirects data from the SoftwareSerial ports to the hardware Serial (over USB to the PC).
Is there any way to bypass the 328p chip, and only use the 16U2, which works as a USB to Serial converter? Will the circuit in the diagram work? By connecting the GND to RST on both the Unos, the 328p gets disabled, which in theory should all me to directly tap into the serial line of the 16U2.
