NDV functionality to re-establish a broken connection (load the lost server context) for Unix.

We are using "Software AG Natural for Windows" and connecting to Ndv on Linux server.
While using the product, our session usually disconnected from the Linux server, due to firewall security regulation.
We use other products with similar connectivity, but they use keep alive mechanism to keep the session from disconnected.
Natural NDV on Mainframe has that functionality to re-establish a broken connection.
We wish Linux Ndv will have the same functionality as Ndv on Mainframe.
