Keep link open
Defines that the IEC-101 link is kept always open even when there is no active
IEC-104 connection. If the functionality is enabled the Arctic sends link test
frames and restarts the IEC-101 link if the test fails. The events are still not
polled before the IEC-104 connection is active.
