Why is OL Terminal disconnecting or misbehaving?

OL Terminal is a browser 3270/5250 emulator (browser-based emulation), not Hub Screens Flow design and not a map player.

Session dropped “while still working”

Admin inactivity timeout still fires if the host is idle even when the browser tab is open. Raise the timeout in Admin → Connectivity, or keep host activity.

Other frequent reports

• Resolution / arrow keys — after a custom screen size, arrows can pan or change size. Reset zoom/size to the host’s 24×80 / 27×132.
• s3270 permissions becoming 777 — the helper binary’s file mode is being reset by the deploy or user. Pin permissions in the install; do not run world-writable.
• DBCS — double-byte is a known gap unless the build you are on documents DBCS support.
• Field End vs end of text — emulator field-exit vs 5250 “end of field” mapping. Check Key Mappings in Admin.

For flow problems on a live session, use Play Flow. For keyboard/session problems, stay in the emulator Admin and User guides.
