Hi Chris, Lurking RPi Linux user here.. Are you talking about having the RPI control the reset line to one or more targets? Would a GPIO pin be sufficient for that, or would we need another output?
Also, what would the serial port on the Pi be used for? Would it connect to a test target serial port and host the ser2net program?
