There is an automatic switching between transmit and receive modes  
that does what you want -- whenever there is something being  
transmitted, it disables the receive chain, and switches back once  
that buffer is empty. Look through the examples for flow graphs with  
both transmit and receive chains. It's called something like auto_tr.
