5250 keyboard workflow
Use printable input, field navigation, Enter, Field Exit, F1 through F24, Page Up, Page Down, Help, and Reset through bounded controls.
Classic terminal, zero client install
Run your IBM i 5250 application in a browser.
PristineScreen400 projects a live, server-controlled 24 by 80 terminal into an accessible browser workspace. Start with the host application you already operate, then add managed access and selected presentation improvements without requiring an RPG rewrite.
Direct answer
What is a browser-based 5250 terminal?
It is a web interface for interacting with an IBM i 5250 application while the terminal connection itself remains on the server. PristineScreen400 renders a browser-safe screen projection and sends bounded field edits and approved terminal keys back through the managed workspace.
Daily operation
A live terminal, not a static picture of one.
PristineScreen400 keeps input synchronized with the current host screen. Stale actions, protected fields, and input while the host keyboard is locked are rejected rather than guessed.
Current-screen enforcement
Edits and keys are serialized against the current workspace revision and terminal screen sequence.
Browser-safe projection
Non-display host values are removed before the connector returns screen content to browser-facing code.
Choose it for the right job
Browser access and desktop emulators solve different operating needs.
PristineScreen400 fits when
- You need centrally managed browser entry for a compatible 24 by 80 application.
- Users should select only assigned IBM i profile grants.
- IBM i passwords should remain server-side.
- You want optional branding, tools, or selected screen templates around Classic access.
Review another approach when
- You require printer emulation or 27 by 132 presentation.
- You depend on desktop-specific macros, multiple simultaneous terminal tabs, or broad workstation integration.
- You need SSO in the current deployment.
- You need an unrestricted IBM i client or general-purpose system API.
Frequently asked questions
Terminal behavior to confirm
Does PristineScreen400 require changes to RPG or COBOL code?
Classic browser access does not require a screen template or an application rewrite. Environment compatibility is confirmed during review.
Is this the same as IBM i Access Client Solutions?
No. ACS is a broad IBM client with mature workstation features. PristineScreen400 is a managed browser workspace focused on application identity, exact profile grants, server-held credentials, bounded tools, and optional presentation layers.
Can users choose an IBM i host?
No. The deployment operator configures and allow-lists the IBM i target. A browser can select only a profile grant assigned to its authenticated application account.
