UPDATED QUESTION: So basically I would like to view live input from the Arduino via Perl and send input to the Arduino via Serial. Hello Group! I can successfully send a command to the serial device and I can see the response when a button is pressed on the device however I would like to see it in real time and not when I hit the enter button again. Thanks in advanced my code is below: 
use Win32::SerialPort;
my $port = Win32::SerialPort->new("COM16") or die "Open Port Failed. $
+!\n";
$port->is_rs232;

$port->initialize();
$port->baudrate(9600);
$port->databits(8);
$port->parity("none");
$port->stopbits(1);
$port->write_settings || undef $port;

sleep(3);


print "STARTING RELAY SIGNAL PROGRAM\n\n";


while (1) {
print "ENTER A SIGNAL COLOR... ";
my $char = <STDIN>;
$char = <STDIN> until defined $char;
chomp($char);

# SEND THE COMMAND TO THE ARDUINO

if ($char =~ /^\d+$/) {
print "\nSENDING $char ...\n\n";
$port->write("$char\r");
}
$port->lookclear();

my $data = $port->lookfor;
if ($data =~ /BONE/) {
print "\nBUTTON PRESSED\n\n";
}
$port->lookclear();
$port->purge_all;

} # END WHILE LOOP
