Hi Patrick,

If you prefer perl, are using a unix flavor, don't mind using a little 
bourne shell within it, and are comfortable coding, write your own... 
the relevant bits would look like:

$output = `(			sleep 1;
	echo $login;		sleep 1;
	echo $password;		sleep 1;
	echo term leng 0;	sleep 1;
	echo "** YOUR COMMAND **";		sleep 3;
	echo "** 2nd COMMAND IF NEEDED **";	sleep 3;
	echo exit;		sleep 1;
	) | /usr/bin/telnet $ip 2>&1`;

or

$output = `(			sleep 1;
	echo $login;		sleep 1;
	echo en;		sleep 1;
	echo $enable;		sleep 1;
	echo term leng 0;	sleep 1;
	echo "** YOUR COMMAND **";		sleep 3;
	echo exit;		sleep 1;
	) | /usr/bin/telnet $ip 2>&1`;

Alternatively if you are only using IOS or IOS-XE, not IOS-XR, and have 
netcat (nc) on your server I'd recommend using it in place of telnet as 
you can run the commands without specifying the sleep needed for the 
responses which greatly speeds up the program.  There may be a way to 
make XR work with it, but I've had no luck...
$output = `(
	echo $login;
	echo $password;
	echo term leng 0;
	echo "** YOUR COMMAND **";
	echo exit;
	) | /usr/bin/nc $ip 23 2>&1`;

Regards,
Scott
