The read function blocks until it has read enough stuff from the port.
But if there is nothing out there to respond, the application hangs.
Very annoying. I've dealt with this kind of thing a zillion times on
embedded realtime systems, but I don't know how to approach it in this
programming environment. Is there a preferred way of solving this problem?

Thanks,
