Hello! Re: 1
That's not how GNU Radio should be used, and thus, it's impossible to do that, architecturally. Connecting blocks pretty much has non- deterministic behaviour w.r.t. to buffer state, and also, without the block connected, your flow graph probably wouldn't be properly connected and couldn't even start! Instead, have a block (not a hier block) that outputs items according to some state. Often, it's easy to transport state transitions as stream tags. Re: 2 Hier blocks shouldn't be involved in signal processing. So, although it's generally possible to make a hier block a message acceptor, it's rarely a good idea.
