Serial data from ESP32 cam only shows up in Serial monitor but not by pyserial

if __name__ == '__main__':
    if len(sys.argv) != 3:
        print("python script serial_port baudrate")
        print("python -m serial.tools.list_ports")

What does pyserial default to, hardware or software handshake, or none?
