Problem with DBMS_OUTPUT

I cannot get my DBMS_OUTPUT working.

The following statement in SQL Plus produces no output:

BEGIN
DBMS_OUTPUT.PUT_LINE('Hello world');
END; does not work though I get the "PL/SQL Procedure successfully completed" message.

Is there some configuration I need to do so DBMS_OUTPUT is echoed to the terminal?

Any help appreciated.
