sorry, maybe I used a wrong parameter for netstat or I did not look carefully enough, not it is there:
udp 0 0 localhost:61111 0.0.0.0:*
However, when I send:
echo "dl3el" | nc -w 1 -u localhost 61111
nothing happens (echo "f" | nc -w 1 localhost 51111 would give the correct frequency back)
When I send:
rigctl -r localhost:61111 -m2 b dl3el
I get: "rig_open: error = IO error"
