Hi, I'm trying to write a simple interactive TCP client that talks to a server, which is written in POE (nonblocking). I'm running the server on win32/cygwin. The following client code is directly from the Cookbook, it works fine from a linux box, but hangs on win32/cygwin, after I type something and hit retern. There are no errors given, just hangs (it takes no inputs, and prints no responses). What can be the issues here? (I guess I probably should check the packets using ethereal, but is there a perlish reason?) By the way, a client using POE works fine also, so probably not the server problem. 
#!/usr/bin/perl -w
# biclient - bidirectional forking client
    use strict;
use IO::Socket;
my ($host, $port, $kidpid, $handle, $line);

unless (@ARGV == 2) { die "usage: $0 host port" }
($host, $port) = @ARGV;

# create a tcp connection to the specified host and port
$handle = IO::Socket::INET->new(Proto     => "tcp",
                                PeerAddr  => $host,
                                PeerPort  => $port)
       or die "can't connect to port $port on $host: $!";

$handle->autoflush(1);              # so output gets there right away
print STDERR "[Connected to $host:$port]\n";

# split the program into two processes, identical twins
die "can't fork: $!" unless defined($kidpid = fork());

if ($kidpid) {                      
    # parent copies the socket to standard output
    while (defined ($line = <$handle>)) {
        print STDOUT $line;
    }
    kill("TERM" => $kidpid);        # send SIGTERM to child
}
else {                              
    # child copies standard input to the socket
    while (defined ($line = <STDIN>)) {
        print $handle $line;
    }
}
exit;
