unable to get IS_ISI (ISP_ISI) to work
Unable to get the insim init packet to work with the new insim version,

connects okay, and can send data. I try and send this

$packet="";
$packet=pack("c", "44");
$packet.=pack("c", "ISP_ISI");
$packet.=pack("c", "1");
$packet.=pack("c", 0);
$packet.=pack("S", $localport);
$packet.=pack("S", "16+32");
$packet.=pack("c", 0);
$packet.=pack("c", 0);
$packet.=pack("c", 0);
$packet.=str_pad($adminPW, 16, "\0");
$packet.=str_pad("LTC Insim", 16, "\0");
fwrite($sender, $packet, strlen($packet));

and, LFS just complains about incorrect packet size, and incorrect byte on first packet.

Using UDP btw.

"ISP_ISI" should not go in the packet, you're supposed to send the value of the constant ISP_ISI.


<?php 
define('ISP_ISI', 1);        //  1 - instruction        : insim initialise
?>

oooh I see.

Thanks
#4 - Krammeh
it still complains about an incorrect packet size.

i wonder if that's correct : $packet.=pack("S", "16+32");

shouldn't that be : $packet.=pack("S", 16+32);
#6 - Krammeh
even with it as $packet.=pack("S", 16+32);, it still complains :|

<?php 
  $localport = 12345;

  $packet  = "";
  $packet .= pack("c", 44);
  $packet .= pack("c", 1);
  $packet .= pack("c", 1);
  $packet .= pack("c", 0);
  $packet .= pack("S", $localport);
  $packet .= pack("S", 16+32);
  $packet .= pack("c", 0);
  $packet .= pack("c", 0);
  $packet .= pack("S", 0);
  $packet .= str_pad($adminPW, 16, "\0");
  $packet .= str_pad("LTC Insim", 16, "\0");

  echo strlen ($packet);
?>

you had a CHAR for Interval where it should be a Short, so your packet was 43 bytes instead of 44
#8 - Krammeh
okay, it connects now. thanks a lot!!!
#9 - Victor
btw, i think you chould write C's for all your c's too - those bytes should be unsigned (C) instead of signed (c)
#10 - Krammeh
they are lowercase...?
#11 - Victor
oops typo in second half of my sentence
#12 - Krammeh
so it should be C and not c?
