This is the final state of the flow graph:
<gr_block file_source (0)> source
noutput_items = 32767
general_work: noutput_items = 32767 result = -1
were_done
<gr_block bytes_to_syms (1)> regular 1:8
max_items_avail = 0
noutput_items = 8184
BLKD_IN
were_done
<gr_block interp_fir_filter_fff (2)> regular 1:2
max_items_avail = 4
noutput_items = 8190
BLKD_IN
were_done
<gr_block frequency_modulator_fc (3)> regular 1:1
max_items_avail = 0
noutput_items = 4094
BLKD_IN
were_done
<gr_block quadrature_demod_cf (4)> regular 1:1
max_items_avail = 1
noutput_items = 8182
BLKD_IN
were_done
<gr_block clock_recovery_mm_ff (5)> regular 2:1
max_items_avail = 9
noutput_items = 8191
BLKD_IN
were_done
<gr_block binary_slicer_fb (6)> regular 1:1
max_items_avail = 0
noutput_items = 32767
BLKD_IN
were_done
It appears that the elements are not draining, although I'm unclear on
why there is what seems to be 9 symbols remaining in the flow despite
the fact that I'm only missing 5 symbols. An EOF related problem?
I'll keep looking...
