[sldev] [Question] TCP/UDP Sim connection

[Tateru Nino]

Your packet should look like this:
U8 (set to 0x40 - 'reliable')
U32 (big endian sequence number)
U8 (set to 0x00)
U32 (big endian: 0xffff0003 - 'UseCircuitCode')
U32 (LITTLE endian - circuit_code you got from the HTTP request to the
login servers)
U8[16] (big endian - session_id from the same HTTP transaction)
U8[16] (big endian - agent_id from the same HTTP transaction)

That's 46 bytes. Send via UDP to sim_ip:sim_port
You should recieve a 12 byte packet in response which contains a single
acknowledgement.
