I'm sorry, I'm a lazy programmer, and when I can ask
The user something and I can pose the question myself...

I'm not gonna load an extra module

#!/usr/bin/perl -w

use strict;
use Term::ReadKey;

my %Prompts=(
        'Step 1: Enter old password: '             => 'oldpass',
        'Step 2: Enter old enable password: '      => 'oldenable',
        'Step 3: Enter new password: '             => 'newpass',
        'Step 4: Confirm new password: '           => 'passconf',
        'Step 5: Enter new enable password : '     => 'newenable',
        'Step 6: Confirm new enable password: '    => 'enableconf');
my $Key;
my %Passwd;
foreach my $Prompt (sort keys %Prompts)
{
 print "$Prompt";
 ReadMode('noecho');
 chomp($Passwd{$Prompt} = <STDIN>);
 ReadMode(0);
};

I hope this wont cost me XP... ;))
