Usage: SET OPS_METHOD [DEFAULT|WALLCHOPS|HYBRID|AUTO]
  Determines how the OPS and WALL commands send messages to all
  channel operators.

  When set to DEFAULT, the commands use the old-style method of sending
  messages to multiple targets.  Use SET MAX_WALL_NICKS to tune the
  maximum number of nicknames to message at one time.

  When set to WALLCHOPS, the client will use the server WALLCHOPS
  command.  Some servers may not support this method, however recent
  versions of the Undernet ircd do.

  When set to HYBRID, the client will use the method of sending a
  message to @#channel.  Some servers may not support this method, however
  Hybrid versions 6 and higher do.

  When set to AUTO, the client will attempt to determine which method
  is supported by the server you are connected to by looking at the server
  version.
