Hi, I am trying to write a script that will connect to the telnet port on my device, send a command, and get the reply back. My script is currently not returning the result of the command I send. 
#!/usr/bin/perl
use strict;
use warnings;
use IO::Socket;

my ($host, $port) = ('111.111.111.111', '23');
my $command = "\$TEMP*";

my $socket = new IO::Socket::INET (
   PeerAddr => $host,
   PeerPort => $port,
   Proto    => 'tcp',
 );

if (!$socket) {
  die "Unable to establish connection to $host\n";
}

print $socket $command;
$socket->getline;
my $output = <$socket>;
$socket->close;

print "$output\n";

So the script is suppose to open a socket on port 23, send the command $TEMP* and then get the result that the device will give. The script either hangs or it just returns the "Welcome to device 'devicename', please input your commands".

Is there anyway to make the script wait and grab the output after the command $TEMP* is input? The device is suppose to return something like $TEMP*,42C.
