code: def server_sends_binary(self, message, name=None, connection=None, label=None):
          
          server, name = self._servers.get_with_name(name)
          server.send(message, alias=connection)

docs: Send raw binary `message`.
  
          If server `name` is not given, uses the latest server. Optional message
          `label` is shown on logs.
  
          Examples:
          | Server sends binary | Hello! |
          | Server sends binary | ${some binary} | Server1 | label=DebugMessage |
          | Server sends binary | ${some binary} | connection=my_connection |
