I am looking for a well behaved utility to toggle the Treo 650 Power_Out pin on and off. I believe apps written for the T5 and E2 should also work as they share the same serial interface.

I have an app that came with my buffered serial cable but it is obnoxious in that it resets the machine every time the setting is toggled.

The serial cable is pcables.com PDCT5-M9-6 Palm to true buffered RS232C, the buffer is powered by the Power_Out pin. It allows the 650 to run the Autotap interface I used with my former M500.
