Close TCP connection

Hi,

I have a Q about closing TCP connections.
To realise a more realistic simulation of WEB Throughput I try to
close the FullTcp agent after they have send one document (close
command).
But when I looked into the trace file I can�t see a finishing procedure
between
the two agents. Does anybody know a method to close an agent, so that
he will send a finishing procedure. Following a short  example of my
code.

$ns at $time "$tcp($i) send $nbytes"
$tcp($i) close

Thanks in advance!
Martin
