+/* 	This file is part the LCDproc driver for various serial VFD Devices.
+
+	It contains the hardwaredependent commands ach characterset.
+
+	If you want to add a new device to the driver add a new section
+	to the displaytype-switch-case in the init-function, add a new load_...
+	function below and fill it with the corrrect commands for the display.
+	(Try wich displaytype works best with your display, copy and modify
+	it's section that is the easiest way I guess.)
