Greetings to everyone. I have a PERL script that needs one more piece of code to make it work properly. The code I need is to read or capture the output after running the 'Y' command. If the output is an error, then the next command that should be issued is a 'N' before continuing the loop. The problem with my script is that by not having this "error checking" code, the script times out and the telnet session is closed. When there is an error, the only other option to enter should be 'N'. Can anyone help?

#!/usr/bin/perl

$user="username";
$pass="password";
$server="##.##.##.##";

use Net::Telnet;
$t = new Net::Telnet;
$t->open("$server");
$t->waitfor('/Enter User Name/');
$t->print("$user");
$t->waitfor('/Enter Password/');
$t->print("$pass");
$t->waitfor('/>/');
$t->print("servord");

open(LIST,"roamers.txt");
@numbers=<LIST>;
foreach $number (@numbers)
{
$t->waitfor('/>/');
$t->print("deo");
$t->waitfor('/>/');
$t->print("");
$t->waitfor('/>/');
$t->print("$number");
$t->waitfor('/>/');
$t->print("cdw");
$t->waitfor('/>/');
$t->print("arw");
$t->waitfor('/>/');
$t->print("\$");
$t->waitfor('/>/');
$t->print("y");
# I need an "error checker" here. If giving the 'Y' command gives an 
# error output, then the following cmd should be 'N' 
# before continuing the loop.
}
close(LIST);

$t->waitfor('/>/');
$t->print("quit all;logout");
