The default exit code when a connection is refused is critical, but I only desire a warning (--refuse=warn). Also, I noticed that (--refuse=ok) returns output that gives the impression that the connection succeeded. The output should be the same "Connection refused" regardless of the desired exit code.

./check_tcp -H localhost -p 999 --refuse=crit
Connection refused
echo $?
2

./check_tcp -H localhost -p 999 --refuse=warn
echo $?
1

./check_tcp -H localhost -p 999 --refuse=ok
TCP OK - 0.000 second response time on port 999|time=0.000182s;;;0.000000;10.000000
echo $?
0
