CQ-3270

The architecture of CQ-3270 consists of several key components designed to facilitate 3270 emulation and mainframe connectivity. The Connection Manager is responsible for establishing and maintaining connections to the mainframe hosts. , SNA over TCP/IP using Enterprise Extender).

The Terminal Emulator provides the user interface, rendering the 3270 display and handling user input. It interprets 3270 data streams and translates user actions into the appropriate commands for the mainframe. The Configuration Manager allows administrators to define and manage connection profiles, security settings, and other parameters.

Configuration files store connection profiles and settings. The communication protocol is primarily TCP/IP, with support for SNA over TCP/IP using Enterprise Extender (EE). The product does not use a database for core functionality, relying instead on configuration files for storing connection profiles and settings.

The GUI provides an interface for administration, including user management and configuration. Authentication methods include user ID and password. Logging capabilities are available for auditing.

Compared to other emulators, CQ-3270's EE support provides enhanced connectivity options. The product uses TCP/IP for communication, and requires specific ports to be open for connectivity.
