I created a simple Gnu Radio flow-graph. In USRP source, i add serial

The problem that i can not save the data in a file.
I got error “Port is not connected”
Can any one help me?

I've cross-posted to discuss-gnuradio, since this isn't really the
"teach myself gnuradio" mailing list.
You've disabled your USRP source, the "real" output of your
complex-to-real is going to a file sink that is configured for
complex-float. Your source refers to a variable,
"gain" that doesn't exist within your graph.
You should probably spend a bit more time with Gnu Radio tutorials.
