Look in the gnuradio-examples/python/digital/tunnel.py and subfiles.

transmit_path.py has a send_pkt function which calls the send_pkt 
function in pkt.py (in the gnuradio python libraries directory), which 
converts a string into the proper format and enqueues it into a message 
queue.

When you're done with the queue, and you want to close up, call the 
send_pkt function with eof = True (enqueues gr.message(1)), which tells 
the queue that no more input is coming and enables the fg to stop.
