(does not include protocol header)
Contains a list of available channels, each terminated by a null byte. The last item should be empty (just a null byte), indicating the end of the list.
For some reason, Diablo II adds extra data to the channel list (as can be seen in game), and older clients list blocked channels, such as Warez and Backstage.
the channel list is seperated by a 0x0D 0x00
Actually, no it's <strong>not</strong> separated by 0x0D 0x00.
It is separated by null-terminators (0x00). You should keep reading until you come across an empty string, or a double 0x00. Of course, you can always keep reading until you reach the end of the packet length, then removing the last channel (if empty), which works also.
