Can you log in with a normal telnet client from the command line?  If so, what exactly do you have to type?

Net::Telnet definitely does send \r\n when you say $t->print():

Here's a simple "telnet server" that simply echoes back in hex what you send it

#!/usr/bin/perl
use IO::Socket;

my $sock = IO::Socket::INET->new(
               LocalAddr => "localhost:9999",
               ReuseAddr => 1,
               Listen    => SOMAXCONN,
           ) or die "couldn't create socket: $!\n";

while (1) {
    my $client = $sock->accept();
    while (my $line = <$client>) {
        print $client join(" ",unpack("(H2)*", $line)), "\n";
    }
    close $client;
}

When you connect to it with a standard telnet client, and press <Enter> once, you get

$ telnet localhost 9999
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

When you connect with the following Net::Telnet code

#!/usr/bin/perl -w
use strict;
use Net::Telnet;

my $t = Net::Telnet->new(Port => 9999);

$t->open("localhost");
$t->print;

my $r = $t->getline;
print $r;

you get exactly the same:

$ ./890020_c.pl

I log in through telnet as follows: telnet 192.168.3.35 <enter> <esc> USER NAME: <user><enter> PASSWORD: <pass><enter> The issue is the blank screen when it connects initially that is causing the issue. Once you hit any char, then the login page loads.
