Telnet session in while loop?

I wrote a script that interfaces with some gear and at one point in the script I have to reboot the card. Now I want to create another telnet session that will re-establish the connection once the card comes back up. I want to use a way that tries to connect and if the connection does not get established then I want it to loop back and try again until the connection is back up which would mean the card has finished rebooting.

I tried adding a while loop in this manner but was unsuccessfull.  Anyone have any ideas on how to implement this?

Oh I forgot to mention that I am using Net::Telnet module for the telnet sessions.

it may be more efficient to just 'ping and sleep' in the while loop:

use Net::Ping;

$p = new Net::Ping;
$up = 0;
$count = 0;
while(!$up and $count<10)
{
  $up = $p->ping( $your_gear_address );
  $count++;
  sleep(2);
}
$p->close();

if($up)
{
  # continue with your telnet session
