Probably i'm wrong, In your scheme you use only RX and TX plus GND wired to COM port; i don't find UART IC for handshake, therefor you can only realize synchronous serial communication, i think. Some model of Ardunino should be UART integrated. As you know, Serial RS232C DTE to DTE can be do by hardware (null modem cable or serial cable + null modem adapter) that cross wires, or by software (for example by checked box, i think).
