It is possible that the trailing newline is the culprit. Note that when you use 
$NT->cmd("1\n");

you will be sending two newlines - the one you specified in the argument to cmd and one that Net::Telnet will add to the end of each command line.

You can try using the put method or setting the output_record_separator to the empty string.
