17 | Purpose : This Module defines the fieldstrength management
18 | device driver for the G23 protocol stack.
19 |
20 | This driver is used to control all fieldstrength related
21 | functions. The driver does support multiple devices and
22 | therefore no open and close functionality is supported.
23 | The driver can be configured to signal different state
24 | transitions. This is done by setting an OS signal or
25 | calling a specified call-back function.
