The TN BRIDGE Emulation Layer is made up of 5 Terminal Emulator components.

These components implement the main features for a terminal emulator program like: Display Screen, Status Bar, Keyboard Handling, Macro Sequences and Profiles.

Implements an emulation panel. This panel shows host data and accepts input data to be sent to the mainframe. The displayed data is formatted according to the data stream format (3270 or 5250).

Implements an emulation status bar. It works joined to the TNBEmulator component, complementing it.

Process the keyboard and maps to Emulation Function Keys and Attention Identifier Keys. The Emulation Function Keys are those which are processed locally to manage the emulator behavior for input data (For example: Tab key, Cursor movement keys, Home key, etc.). The Attention Identifier Keys are those which provoke sending data and the properly Attention Identifier Code (For example: Enter key, PF01 key, Clear key, etc.).

Implements the recording and playing mainframe navigation sequences to automate tasks.

Implements a common interface for saving and loading profiles like screen emulation styles, host connection profiles and macro sequences.
