Osgeld:
I just got a FTDI cable (yea behind the times) and read in some very old post that RTS wouldnt work for reset, is that changed?
I believe the very first arduino board designed to have a auto-reset function used the RTS signal. On later versions they changed the hardware to use DTR instead, but for legacy compatibility reasons had the IDE pulse both DTR and RTS. Not sure that is still the case or not as sometime in the version changes they handed off the activation of the control signal(s) from the IDE directly to AVRDUDE directly. But Nick's example implies the RTS is still pulsed.
