Agreed, since this is a feature that most people do not need,
I would suggest that you replicate the internals of femon to
suit your data capturing needs.

On the other side of argument, the ber and unc fields is probably
oversized, and could be reduced, but this is a binary incompatible
change. So it's not really feasible in the real world :(

I would guess that something like:

time                status  signal  snr   ber        unc        status
Mar 24 15:24:46     1f      fd10    e334  00000018   00000000   FE_HAS_LOCK
Mar 24 15:24:47     1f      fd10    e334  00000018   00000000   FE_HAS_LOCK

Would work..
