d820

special initial packet:
long op_code = 0x20;
long arg1 = 0;
long arg2 = PID + 1000;

followed by 

packet structure (0x218 bytes)
long op_code; (0x0 offset)
long arg1; (0x4 offset) usually 0x64 from phatd so far (signature for a reply?)
long arg2; (0x8 offset) 
long arg3; (0xC offset)
long arg4; (0x10 offset)
long arg5; (0x14 offset)
long arg6; (0x18 offset)
