CLEO TN3270/5250

The architecture of CLEO TN3270/5250 comprises several key components: the session manager, the protocol engine, and the terminal emulator. The session manager handles multiple concurrent sessions, providing a centralized point for session control. The protocol engine manages the communication protocols, primarily TCP/IP, ensuring reliable data transfer between the client and the mainframe.

The terminal emulator interprets and renders the data received from the mainframe, presenting it to the user in a readable format. Configuration is primarily managed through configuration files, allowing administrators to customize terminal types, keyboard mappings, and connection parameters. The product does not use a database for persistent storage; session data is managed in memory.

Network requirements include the ability to communicate over TCP/IP on configurable ports. The product supports various security features, including authentication and encryption, to protect sensitive data during transmission. Compared to other emulators, CLEO TN3270/5250 offers enhanced security features and robust session management capabilities.

The product's design prioritizes performance and reliability in enterprise environments.
