Programming RBBB with another's ftdi chip

So I have a RBBB in one of my projects and I would like to be able to reprogram it easily (I don't have a ftdi breakout). I have a duemilanove, so obviously I can just swap the chips to reprogram. But I would like to avoid having to remove the chips.

Can I connect certain wires from the duemilanove to the rbbb and remove the 328 and use it as a ftdi usb-serial converter? I would guess I'd just connect: RX + TX 5v + GND Something with the reset pin, for the autoreset, but I'm not sure what

Thanks!

Yes, if you remove the 328 from the Du board and run Rx,Tx, gnd, +5vdc (+5v, not if your rbbb already has it's Vcc active) and then also connect the Du reset to the rbbb reset. Should work just fine, auto-reset and all.

Okay thanks!
