BYTE[1] sequence number
BYTE[4] fastwalk prevention key

Notes
Sequence number starts at 0, after a reset. However, if 255 is reached, the next seq # is 1, not 0.

Fastwalk prevention notes: each 0x02 pops the top element from fastwalk key stack. (0xbf sub1 init. fastwalk stack, 0xbf sub2 pushes an element to stack)
If stack is empty key value is 0. (-> never set keys to 0 in 0xbf sub 1/2)
Because client sometimes sends bursts of 0x02�s DON�T check for a certain top stack value.
The only safe way to detect fastwalk: push a key after EACH x021, 0x22, (=send 0xbf sub 2) check in 0x02 for stack emptyness.

If empty -> fastwalk alert.
Note that actual key values are irrelevant. (just don�t use 0)
Of course without perfect 0x02/0x21/0x22 synch (serverside) it�s useless to use fastwalk detection.
Last but not least: fastwalk detection adds 9 bytes per step and player !

Notes
Types: 0x00 � �It starts to rain�, 0x01 � �A fierce storm approaches.�, 0x02 � �It begins to snow�, 0x03 - �A storm is brewing.�, 0xFF � None (turns off sound effects), 0xFE (no effect?? Set temperature?)

Maximum number of weather effects on screen is 70.
If it is raining, you can add snow by setting the num to the num of rain currently going, plus the number of snow you want.
Weather messages are only displayed when weather starts.
Weather will end automatically after 6 minutes without any weather change packets.
You can totally end weather (to display a new message) by teleporting. I think it�s either the 0x78 or 0x20 messages that reset it, though I haven�t checked to be sure (other possibilities, 0x4F or 0x4E)

Notes
The model # should never be trusted.

Once the server requests the client to target something, the server can undo this also. You can "kill" the targetting cursor faithfully and without any bugs. Send another Packet with Type set to 0 (Object), Cursor ID 00000000, and Cursor Type as 3. The client will respond to this by sending a response to the original request just as if the user had hit ESC to cancel targetting.

Notes
For pre 2.0.7 clients Type is always < 0xc0. Uox based emus convert post 2.0.7 data of this packet to pre 2.0.7 data if Type >=0xc0.

(different view of it)
If Mode&0xc0 then there are keywords (from speech.mul) present.
Keywords:
The first 12 bits = the number of keywords present. The keywords are included right after this, each one is 12 bits also.
The keywords are padded to the closest byte. For example, if there are 2 keywords, it will take up 5 bytes. 12bits for the number, and 12 bits for each keyword. 12+12+12=36. Which will be padded 4 bits to 40 bits or 5 bytes.

Notes
In gump packets, and with any EMU (POL for sure) the "ID" is the # of the script's PID that fired the gump. This can be used via specific 0xBF packets to send the ID to the client to force closing of the gump from the server. When this is done, the client Auto Responds as if it had "exited" the menu normally so the serverside script will handle it as such.

Subcommand 2: Server Sent. This key is added to the top of the stack. In other words, it�s the one that will be used next. Basically, the other 5 only get used when the client is sending moves faster than the server is responding.

Subcommand 4: Server Sent.

Subcommand 5: Client Sent.

Subcommand 6: Sent by both. Contains subcommands for 0x6 for the party system. Be sure you check the packet listing good before attempting these.
