Sending an UDP packet triggers the readout (but the buffer must be filled by sending many "multi" hits)
Some comment about UDP recv buffers,
could be helpful in the future if we loose some events from TRB3
Reducing buffer to see hits in AcquRoot earlier
Sending many events very fast works (but Run must be ended to flush buffers)
Command to send the packets:
for ((i=0;i<200;i++)); do echo "blu" | nc -q -vv 192.168.1.1 50000 -u; done;
No fCtrl needs to be set in TDAQ_TRB3.cc
This is the correct fflush, but don't know if still helps with segfaults
Starting to receive TRB3 packets, use printf instead of echo for netcat!
