+|  Purpose :  This Module defines the fieldstrength management
+|             device driver for the G23 protocol stack.
+|             
+|             This driver is used to control all fieldstrength related
+|             functions. The driver does support multiple devices and
+|             therefore no open and close functionality is supported.
+|             The driver can be configured to signal different state
+|             transitions. This is done by setting an OS signal or
+|             calling a specified call-back function.
