Host Links

Host Links is a set of integrated products providing Bull and IBM legacy application access to users in Open Systems networks. Host Links make it possible for you to replace proprietary networks and terminals with commodity network links and workstations, and give them all access to your mission critical legacy applications.


Open Systems servers and commodity network links to your legacy systems reduce your networking costs, avoid training costs associated with proprietary technology and open the way to increased performance, better system monitoring and state of the art security.


Host Links includes server-based terminal emulators, network printer emulators, application programming interfaces, network gateways, load balancing and monitoring tools for users of departmental servers. The products provide connectivity to Bull and IBM legacy applications from UNIX, Linux and Windows environments.
