Hi Eugueny, (cc list)
Good question. Took me some time to think back....
I've taken the liberty of cc'ing the list in case anyone
else comes
along this 'path'/thread.
I think this is what happened.
Regarding my first mail in this thread:
The error message was (I think) due to the port being in
use(?)
Regarding:
http://rubyforge.org/pipermail/eventmachine
-talk/2006-May/000060.html
Well. I understood so little of what was happening in EM
that what I
thought was unexpected behavior was, in fact, perfect
behavior...
The sequence of printed '[]' reflect the fact that no client
has yet
connected to that server 
The following example helped me work out what was happening.
From
this I added snippets from the code in
http://rubyforge.org/pipermail/eventmachine
-talk/2006-May/000060.html
I hope the following helps?
#### Start server code ####
#
#Start an instance of irb in a new shell
#
$stderr.sync = $stdout.sync = true
require 'rubygems'
require 'eventmachine'
module EchoServer
def receive_data data
puts "Server received: #"
send_data ">>>you sent: #"
puts "Server sent: >>>you sent:
#"
close_connection if data =~ /quit/i
end
end
EventMachine::run {
EventMachine::start_server "192.168.1.1", 8100,
EchoServer
}
#### End server code ####
#### Start client code ####
#
#Start another instance of irb in a new shell
#
$stderr.sync = $stdout.sync = true
require 'rubygems'
require 'eventmachine'
class EchoClient < EventMachine::Connection
def receive_data data
puts "Client Received: #"
close_connection if data =~ /quit/i
end
end
cnt=0
EventMachine::run {
emc = EventMachine::connect "192.168.1.1",
8100, EchoClient
EventMachine.add_periodic_timer(5) {cnt +=1;
emc.send_data "Message: #"}
}
#### End client code ####
