B. High level mode
This mode is using a xinetd driven application that can use a socket to communicate.
For the moment, there are some limitations, depending on the level mode, but we are
constantly work to add more and more functions on the high level mode too, because this
mode can be used with less or no complications, even with a browser based application.
Below you can find a table with a level modes comparison:
