Packet Information

Message ID:0x00
Message Name:SID_NULL
Direction:Client -> Server (Sent)
Used By:Starcraft Shareware, Starcraft Broodwar, Diablo Shareware, Diablo II, Warcraft II, Warcraft III: The Frozen Throne, Starcraft, Starcraft Japanese, Diablo, Diablo, Warcraft III
Remarks:Keeps the connection alive. This message should be sent to the server every 8 minutes (approximately).

The server will send this to you automatically, you do not have to reply to it. You should send this on your own never-ending timer for at least as often as does (give or take a few seconds).

This packet is used to detect if your TCP connection has gone dead, to the point where you will never receive data from the server ever again until you reconnect your connection. A situation such as this can be created by unplugging your internet connection for a few minutes, or if your internet is dropped for whatever reason.

I'm guessing this is what Event_NULL (2000) is for the Telnet Protocol as well.
