 * Setting multiple ports in one requests are set one after another, but the code
   is optimized and nothing unnecessary is done in between (it takes about 2-5ms on an idle Raspberry Pi to set all 17 ports, some artificial load (e.g.'find /' in the background) will slow it down to 10-15ms).
 * Cronjobs (exact to the second) for output ports are based on [quartz-scheduler.org](http://quartz-scheduler.org/documentation/quartz-2.1.x/tutorials/crontrigger). Output ports can be set conditionally and you have a simple but powerful semaphore mechanism.
+*   You may define your own variables with a prefix VIRTUAL which are persisted in memory (unknown virtual variables default to "0").

-Watch out that your values (especially for VIRTUAL ports) must be numeric or you get a NumberFormatException.
