Browser-based 3270 and 5250 emulation

Connect to IBM Z and IBM i apps from any modern browser with full 3270/5250 field editing, function keys, and mappings—no desktop emulator.

OL Terminal provides secure browser-based 3270 and 5250 terminal access to IBM Z and IBM i. Users start a session from the web UI, interact with green-screen applications like a traditional emulator, and keep sessions alive across reconnects—without installing desktop terminal software. This is terminal emulation—not a map player (OL Screener / OL Next).
