[ns] Resetting a TCP connection

[Wael Noureddine <waelnour@toledo.stanford.edu>]

Hello all,

I would like to close a TCP connection when its done and clear its state
to start a fresh connection. Is that possible? agent_->close() within an
application doesn't seem to do that. In addition I would like to find a
way to notify the application that a file was sent (idle()-resume() 
doen't seen to work either);
Thanks,

Wael
