Yeah I was planning to add another Perl programming book to my list....
Thanks for all hints so far... I've got the following to work now using
IO::Select
Properly send & receive to and from server.
I can esablish a DCC connection over additional socket, but then I only
get the data from the DCC socket, and no-longer the data from the server
socket, untill the DCC socket is closed.....



<code snip>
$con = IO::Socket::INET->new(PeerAddr=>"$server",
                             PeerPort=>"$port",
                             Proto=>'tcp',
                             Timeout=>'30') || print "Error! $!\n";
$select = IO::Select->new($con);

while(@ready = $select->can_write) {
  for $socket (@ready) {
  #The DCC Connection
    if($socket == $dcc) {
      $talk = <$dcc>;
      print $talk;
  #The Server Connection
    } elsif ($socket == $con)  {
      $answer = <$con>;
      print $answer;    # echo everything that comes from the server to
screen
      #lots of other stuff here
      if ($answer =~ /:(.*)\!.* PRIVMSG $me :\001DCC CHAT chat (\d+)
(\d+)\001\r\n/) {
        print "Received dcc from $1 with $2 and $3\n";
        $dcc = IO::Socket::INET->new(PeerAddr=>"$2",
                                     PeerPort=>"$3",
                                     Proto=>'tcp',
                                     Timeout=>'30') || print "Error!
$!\n";
        print $dcc "Please Enter Your Password!\n";
        $select = IO::Select->new($dcc);
      }
    } else {
      print "more stuff to come here"
    }
  }
}
</code snip>
