This question is a follow on to: How to Get XTerm Title

I can read the window title Putty is sending only after doing a Enter from the keyboard. Do I need to do a non-blocking read from the keyboard? Is there a way I can send a "\n" to STDIN? 
#!/usr/bin/perl

use strict;
use warnings;

$| = 1;

#
# Main
#
my $SaveSTDIN;
print "\033[21t;";
my $Response = <STDIN>;
open(STDIN, "<&$SaveSTDIN");
print("\$Response\[$Response\]\n");
my @Characters = split(//, $Response);
foreach my $Character (@Characters)
   {
   print("\[$Character\]\[" . (ord($Character)) . "\]\n");
   }
