Everything your users need from a 3270 emulator. Nothing they have to relearn.
A fast, signed Windows desktop app built on public standards, with the importers, keyboard fidelity and security controls large organizations require.
Built on open standards
WND Terminal implements the published TN3270E protocol and the full 3270 data stream, so it works with z/OS applications under CICS, IMS and TSO without host changes.
- TN3270E (RFC 2355) with LU name and device-type requests
- Model 2, 3, 4 and 5 screens, from 24×80 to 27×132
- Extended colour and highlighting, protected and input fields
- EBCDIC code pages including 037 and 1140 with the euro
- Auto-reconnect and keep-alive for long-running sessions
Feature overview
Session importers
Bring Reflection session and keymap files and IBM PCOMM profiles across in minutes. Extra! sessions convert through Reflection format.
Keyboard fidelity
PF1–PF24, PA1–PA3, Clear, Reset, Attn and SysReq. A keymap editor with presets that mirror familiar emulators.
Modern desktop
Tabbed sessions, crisp scalable fonts, field-aware copy and paste, hotspots and a clear status line.
Printing
TN3270E printer sessions to any Windows printer or PDF, plus print-screen with headers and footers.
File transfer
IND$FILE transfers between PC and host in both directions, with text and binary modes.
Central configuration
Push signed profiles and keymaps through a file share, Intune or HTTPS. Lock settings and export usage for licensing.
Encryption
TLS 1.2 and 1.3 through a FIPS 140-3 validated cryptographic module, with client certificates from the Windows certificate store.
Flight recorder
Capture the 3270 data stream with screen contents redacted by default, then replay it to pinpoint any display issue.
Accessibility
Screen-reader support for JAWS and NVDA, high-contrast themes and full keyboard navigation. VPAT available on request.
Where WND Terminal is going
We build what customers need next, in the open. Current priorities:
Browser access gateway
A container you run in your own data centre or cloud account, with SSO, so users can reach the host from a browser. Shipped as an OCI image, Helm chart and VM appliance.
Automation and RPA
An HLLAPI-compatible automation interface for UiPath, Power Automate and Blue Prism, plus macro record and playback.
AI assistance
Plain-English help on any screen, macros written from a recorded session, and legacy macros converted automatically with human review.
More hosts
TN5250 for IBM i, VT over SSH for Unix hosts, and Mac and Linux desktops.
See it on your own mainframe
Install it on a handful of PCs, import your existing sessions and keymaps, and let a real team use it next to what you run today. Free, two to four weeks, no commitment.
