I want to use this server framework for a project of mine, but somehow when a client connects to it using telnet or something similar, the server just sits there and waits for the user to type any button, before sending that which he was supposed to send right away. I tried to set autoflush to 1, but that didnt seem to work either. Can anyone explain to me, what iam doing wrong? Thanks in advance! 
#taken from perlnet
#!/usr/bin/perl

use IO::Socket;
# include the select package
use IO::Select;

# they're counting the number of connections $nconnections_old = 0;
$nconnections_new = 0;
$port = 1234;

$new_client = IO::Socket::INET->new(Proto=>"tcp", LocalPort=>$port, Li
+sten=>$max_clients, Reuse=>1);

# create a new selection and add our basic socket for incoming connect
+ions
$sel = IO::Select->new($new_client);

while (@ready = $sel->can_read) {

 # for every readable socket
 foreach $client (@ready) {

  # check if it is the basic socket
  if ($client == $new_client) {

   # if it is establish new connection
   $add = $client->accept;

   # add new socket to the selection
   $sel->add($add);

   # increase number of connections
   $nconnections_new++;


  # if it is an already established connectection
} else {
#It waits for user input here, like an enter, or somehing before it pr
+ints the string in  $hey to the client.. Why??

$hey="Hey, Iam the server, how are you?";
syswrite($client, $hey, length($hey));

  }
 }

 # if number of connections has changed, print it
 if ($nconnections_old != $nconnections_new) {
  print "Already $nconnections_new connection(s)\n";
  $nconnections_old++;
 }
}
