Subject: How to realize that a TCPSocket doesn't give any more lines as answer?

Hi,
I'm writing a little tcp-client which connects to a tcp-server, sends a command and recieves an answer. If I do something like that:

#!/usr/bin/env ruby

$VERBOSE=true

require 'socket'
...
begin
	socket = TCPSocket.new($ip,$port) 
rescue
	puts "error: #{$!}"
	exit 1
end

socket.print command

answer=socket.gets

socket.close


It works if the server sends just one line. But I don't know how many lines the server answers. So I tried something like that:

answers=[]
while answer=socket.gets
	answers<<answer
end

But this results in the while-loop never ending. Even if just one line is the answer the while loop does simply never end :( Any idea how to do this?
