Thanks a lot, David. Don't know for sure if your suggestion is the solution to 
my problem, but so far it looks good. So the inline battery gets its power 
from the PC through the DTR and RTS wire? Thought there's also a Vcc wire. Or 
doesn't the Vcc deliver enough power?

You seem to just open the serial port and then wait until ad infinitum. Does 
Linux set DTR and RTS to high and clears them when closing the port?

    -Chris.
