Well, in that case as per another thread on ecos-discuss, you can either:

- use select(), but this has a number of overheads
- use a separate thread to read data, and then signal other threads in your
- or just go ahead and modify the source in the driver itself! e.g. by
waking up a thread in the serial DSR. This is one of the advantages of open
source after all.
