Yup. Trying to think of a way round the problem.
Johannes suggested having the frontend thread poll the values regularly (e.g.
once a second), and cache the values internally. Then the IOCTLs called by
the user application return those internal cached values.
Johannes, why is blocking in the IOCTLs to monitor the BER etc bad? Is it
because the API is defined not to?
