And you? I believe Neil is right here, and this kind of shortcut can not be taken.

There's UART, long rs/232 cable, and a GPS.
UART needs some kind of power supply, to present voltages on the rs/232 cable.
GPS needs some kind of power supply to work.
They are different power supplies, and we should have way to tell them apart. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
