This means that you could replace the reset button on the bottom of the board with a transistor (+ resistor if there isn't already one) and be able to activate the reset button from the comfort of your terminal. If you coupled this with a remotely switchable power supply, you could easily put the router into recovery mode without being physically present (or needing to fiddle with paperclips). I presume it should be possible to enter the factory recovery mode via the uboot prompt somehow (thus making the reset button redundant), but I haven't figured that out yet. If anyone has suggestions I would love to hear them, as the Openwrt wiki didn't prove as useful as I'd hoped in this regard. --steve
