Perhaps Net::Telnet is not the right module to use. You might try IO::Socket::INET. If it's a server like an HTTP server you probably don't need any of the telnet option negotiation stuff anyway.

Does it respond when you send it commands? Then you can just assume that you have a 'prompt' if you get connected to it. Send a command and wait for a response. Then send the next command, etc. Here's how it could work using IO::Socket::INET: 

use IO::Socket::INET;

my $s = new IO::Socket::INET(PeerAddr => ..., PeerPort => ..., Proto =
+> 'tcp');
unless ($s) { die "unable to connect..." }

# we are connected, so just start sending commands

print $s "first command\r\n";
my $resp = <$s>; # expect one line response
print $s "second command\r\n";
...
