Actually, I don't think it needs to be run as a service for USB access - 
it just requires libusb-win32 to be installed - but I could be wrong.

Windows doesn't have the Unix concept of process "signals". When running 
from the console, you can hit ctrl+c and BRLTTY will be notified. 
However, once detached, there's no specific mechanism to notify a 
console application that it should exit gracefully. This comes from the 
fact that Windows is primarily a GUI environment, so the solution in 
Windows is normally to have a window which can receive window messages.
