So the problem is just powering it. There's a industry standard for RS232 used by Bluetooth bridge manufacturers to supply power on an unused pin. So, just fly a wire from somewhere inside over to the RS232 port, and another wire on the Wimodem, I guess. Then I can hook my juice pack to the m100 if I even need it. -- John.
