iWay Emulation Adapter (3270/5250) Recorder mode enables you to capture your mainframe application screens and end user keystrokes using Telnet Designer in terminal mode and then stores these screens and keystrokes in a binary file.

This file can then be used by Player Server to simulate a connection to the mainframe, allowing you to continue your development without a live connection. Capturing a session in Recorder mode is useful for offline development, testing, benchmarking, prototyping, debugging, and demonstration purposes.
