Capturing DBMS_OUTPUT.PUT_LINE Output

I have a very simple need to execute a SQL procedure in PLP and capture the output of DBMS_OUTPUT.PUT_LINE.

I am using a SQL General Component with the SQL "{ call ELN.AAA_TESTOUTPUT() }".  All this procedure does is call PUT_LINE.

Is this possible, or am I making a newbie mistake?

Thank you,
