How to send <ESC> to a telnet server??

[G520]

Hi

I have been getting statistical rapports from a machine via a
telnet server. Until now it has been done manually. However
I want to automate the proccess, and scedule a PHP script to
run everyday.

Using my terminal, I give the command to order a rapport,
and then press <ESC>. Then the rapport is printed out.

Using a PHP script I can order a rapport, all works fine,
except I can not get the printout. When I try to send <ESC>
the telnet server responds with "syntax fault" so
I'm not doing it right.

I have tried the following:

$do_esc=chr(27) ;
fputs ($fp, "$do_esc");

and

fputs ($fp, "\e");

Any ideas???



<?php
$address = '100.100.1.5024 ';
$port = 5000;
$fp = fsockopen($addr ess,$port);
$s='o';
$s=fgets($fp,12 8); //the telnet server responds when connected
echo("<br>$s<br >");

fputs ($fp, "SOME-COMMAND"); //some command to order a rapport
$s=fgets($fp,12 8);
echo("<br>$s<br >"); //telnet server responds with "rapport failed" or "executed"

/*
Here the tricky part starts,
trying to get the rapport
printed out. No success so far.
To get the rapport printed out
<ESC> has to sent to the telnet
server
*/

$do_esc=chr(27) ;
fputs ($fp, "$do_esc"); //this does not work, trying to
//send <ESC> to the telnet server.

while (!strstr($t,'EN D')) { // supposed to get the printout
$t=fgets ($fp,128); // that never comes
echo("<br>$t");
}
fclose($fp);
?>

define('ESCAPE' , 0x1B);
fputs($fp, ESCAPE . "\n"); // probably needs the \n for the recieving end to process the data.
fflush($fp); // make sure the data is sent to the recieving end now...

Telnet escape is actually ^] . Try that.

Thanks guys, but I am:

WRONG – WRONG – WRONG !!!!!!!!

My terminal program translates <ESC> to <CTR>+d

So I need a way to send <CTR>+d and not <ESC> to the telnet server.

Anyone know how I can do this????

$ctrld=chr(4);
fwrite ($fp, $ctrld,1);
