Should be a simple question. I'm writing a script using Expect.pm to automate a curses-based process. I need to send IBM scan codes (pgdn, pgup, and arrow keys in particular) to the spanwed process. 
#!/usr/local/bin/perl -w

use Expect;
use strict;

# Debugging stuff.
$Expect::Log_Stdout=1;
$Expect::Debug=1;

my $exp = Expect->spawn('curses-prog')
  or die "Cannot spawn curses-prog: $!\n";
if ($exp->expect(10, 'Menu item 1')) { print $exp "\0402" };

I'm pretty sure that my notation for sending the needed control characters is incorrect. If anyone could point me in the right direction, it'd be much appreciated.
