Ouch that hurts!

win_extserialport.cpp should launch another thread that does a
(blocking) WaitCommEvent on the serial port and emits the signal. That
is quickly getting messy though.

Easier is to revert those changes (just that revision please) and
add a sleep in the loop to make sure that the thread is not
permanently hogging cpu. It is not as good, but will still help batterylife.

PS. maybe the added value of gpsd then is not to have to deal with messy
serial communications and instead having a simple tcp socket to deal with
:)
