+The commands as descrived above should also work over a network connection,
+however I don't own such projector and have implemented the network
+functionality using a serial to network bridge. The network support for native
+networked BenQ projectors is thus experimental. Let me know if your network
+connected BenQ projector works.

+
+It has to be said that a direct serial conection to the projector is much more
+responsive than using a network connection, at least when using a serial to
+network bridge. Maybe this is different on a native networked BenQ projector or
+using ethernet instead of WiFi.
