ACR Protocol?

[Nightmare]

I'm writing a small check server script in PHP and do not know what the ACR protocol is? I have tried udp://, http:// acr://(I know seems stupid) but none of those work. Any ideas? Still on AC protocol?

It's UDP...

Read the old master-server code at https://sourceforge.net/projects/assaultcuber-ms/files/

I have tried UDP and failed, seen the MS code, tried to fix my script, just can't, here it is.

PHP Code:

<title>Server Status</title>
<p>This page is for my servers, gaming, and more.</p>
<?php
$ip = "udp://127.0.0.1"; 
$port = 280; 
if (! $sock = @fsockopen($ip, $port, $num, $error, 200)) 
echo '<B><FONT COLOR=red>Offline</b></FONT>'; 
else{ 
echo '<B><FONT COLOR=lime>Online</b></FONT>'; 
fclose($sock); 
} 
?>

You have to send 1 non-null byte to the address @ port + 1.
Example:
Send to (udp://addrport+1)) anything that isn't "\0"
Check for response with fread.
