This indicates detection of the DNP3 function Enable Spontaneous Messages encapsulated by RealPort Protocol.
RealPort (Digi Net C/X) is a proprietary Serial-over-LAN encapsulation protocol. It provides a virtual connection to serial devices anywhere on the network by encapsulating ICS protocol data in a TCP based protocol. Remote serial devices are connected to a Digi device server or terminal server somewhere on the network and applications connect to them using a Digi RealPort software that installs a driver exposing one or several virtual serial ports.
DNP3 (Distributed Network Protocol) is a set of communication protocols used between components in process automation systems. It is used primarily in utilities like electric or water companies. The communication is done between a master station and Remote Terminal Units (RTUs) or Intelligent Electronic Devices (IEDs).
