IGNORE	Don't add the new ASDU when the queue is full.
THROW_EXCEPTION	Don't add the new ASDU when the queue is full and throw an exception.

Server mode (redundancy group support)

Enumerator
SINGLE_REDUNDANCY_GROUP	There is only one redundancy group. There can only be one active connections. All other connections are standy connections.
CONNECTION_IS_REDUNDANCY_GROUP	Every connection is an own redundancy group. This enables simple multi-client server.
MULTIPLE_REDUNDANCY_GROUPS	Mutliple redundancy groups. Each redundancy group can have only a single active connection. Each redundancy group has its own event queue.

delegate bool lib60870.CS104.ConnectionRequestHandler	(	object	parameter,
		IPAddress	ipAddress )

Connection request handler is called when a client tries to connect to the server.
