I will provide some pseudocode in this post.
Checking if a serial has been banned by BattleEye
1. Get the BattleEye-GUID of the serial.
2. Sent 4 randoms characters and the BEGuid via UDP to 81.0.236.117 on port 2324 and wait for a response:
3. If the response contains the string "Global", "Ban" or "Global Ban" the serial has been banned, otherwise it's clean! 
Does anybody know, how Darky's program is checking if the serial is VALID and PLAYBLE? I can provide a Wireshark-record of the packets if necessary.
Feel free to contribute!

Code:
string BEGuid = md5("BE" + md5("XXXX-XXXXX-XXXXX-XXXXX-XXXXX")); // Replace with your serial
Code:
UDPClient.send("some" + BEGuid); // 'some' can be anything that is 4 chars long. Ex: 'aosq', 'fido', 'blub'
