DESCRIPTION:

Eccet can be fed with commands by tcp connections. As multiple
instances of Eccet are allowed to be run at the same time,
the ports cannot be static, but are assigned in a "first free
port in a range" manner. Thus if you want to connect to a
specific voxren instance, you have to query this value.
- listenport (int) the port on which the command interface
  listens. This interface can be used by telnet, netcat or
  similar clients.
- httpport (int) the port on which a minimal webserver listens
  for AJAX-style requests. This is e.g. used by the wizards.
