I am reading the Perl cookbook and trying the example of bidirectional client, however it doesn't work. it only outputs one line responded back from the server, please advise: 

use strict;
use IO::Socket;
my ($line, $obj, $pid, $input);
$obj = IO::Socket::INET->new(PeerAddr => "some.com",
                        PeerPort => 7777,
                        Proto => "tcp",
                        Timeout => 60,
                        );

die "cant fork" unless (defined ($pid=fork()));

if ($pid) {
                while (defined ($line = <$obj>))  {
                print STDOUT $line;}
kill 9, $pid;
}
else {
        while (defined ($input = <STDIN>)) {
                print $obj $input;
        }
}
