Message Format:
(does not include protocol header)
(UINT32) Product ID 


Requests a list of channels that the client is permitted to enter.

In the past this packet returned a product list for the specified Product ID, however, the Product ID field is now ignored -- it does not need to be a valid Product ID, and can be set to zero. The list of channels returned will be for the client's product, as specified during the client's logon.




On PvPGN, due to an outdated interpretation of the protocol, this packet is solely responsible for determining your product. Nothing else you do leading up to the sending of this packet matters (including the version check) in that determination.
