I presume this is the sort of thing you want (this is a server that accepts conns and listens/writes to them all asyncronously) but a client would be similar. It is not entirely clear what you actually want to do: 

use IO::Select;
use IO::Socket;

$lsn = new IO::Socket::INET(Listen => 1, LocalPort => 8080);
$sel = new IO::Select( $lsn );

while(@ready = $sel->can_read) {
    foreach $fh (@ready) {
        if($fh == $lsn) {
            # Create a new socket to handle more conns
            $new = $lsn->accept;
            $sel->add($new);     # register it with IO::Select
        }
        else {
            # Process socket
            my $data = <$fh>;
            if ( $data =~ m/exit/i ) {
                print $fh "Sayonara!\n";
                $sel->remove($fh);
                $fh->close;
            }
            else {
                print $fh "Hello $data\n";
            }
        }
    }
}

Run the server in a command window. Open any number of other command windows and telnet localhost 8080 Talk to the server and it will talk back to that telnet session until you type exit.
