connections (@var{host}:@var{d},@code{reverse}), the @var{d} argument
is a TCP port number, not a display number.
+@item websocket
+
+Opens an additional TCP listening port dedicated to VNC Websocket connections.
+By defintion the Websocket port is 5700+@var{display}. If @var{host} is
+specified connections will only be allowed from this host.
+As an alternative the Websocket port could be specified by using
+@code{websocket}=@var{port}.
+
@item password
Require that password based authentication is used for client connections.
