[Discuss-gnuradio] How to send USRP data to the terminal window

[Tony]

I'm operating GNU Radio 2.8 on Ubuntu 6.06 LTS and using USRP mostly with the DBSRX rev 2.1 daughterboard.  Can someone comment on 2 questions.

How can you display the raw or processed USRP I & Q data on the screen?  I've done this by using something like this:

.
.
.
sink1 = gr.complex_to_float()
sink2 = gr.file_sink(gr.sizeof_float,"/dev/tty")
fg.connect(self,sink1,sink2)
.
.

but I'd like to refine the data output, time stamp it and only have it display based on one or more criterions.  Is it reasonable to do this in Python or is sending the data to another process a better solution?

What is the format of the USRP complex output and the FFT output?  Is it documented somewhere?

Many thanks to all that have worked on the GNU Radio project.  I hope to become a contributing member as I gain more skill here.
