Scrollback

The browser keeps up to 2,500 rendered terminal lines. New output follows automatically while the viewport is near the bottom. Scrolling upward pauses follow mode so incoming text does not move the viewport.

While follow mode is paused, a compact live tail shows the newest output at the bottom of the terminal. Press PageUp and PageDown from the command input to scroll the main terminal. Press Ctrl+Enter or use the down-arrow button to return to the newest output and resume following.

Rendering

• ANSI foreground and background colors are rendered.
• Bright colors, 256-color mode, and truecolor sequences are supported.
• Bold, dim, italic, underline, and inverse styles are supported.
• HTTP and HTTPS links in output are clickable.
• Basic terminal controls such as carriage return, backspace, line erase, and screen clear are handled.

Input

Clicking the terminal focuses the command input unless you are selecting text or clicking a link. Browser password managers are discouraged on the command input, and password mode is enabled when the telnet session requests it.

If the MUD sends prompt text through BatClient, the command input marker shows state.prompt > instead of a static prompt marker.

Command history supports prefix matching. If you type say and press Up, history cycles through commands starting with say.

Press Tab to complete the word at the cursor from recent command history and terminal scrollback. Repeated Tab presses cycle forward through matches; Shift+Tab cycles backward. Matching is case-insensitive and uses the typed prefix.

The Terminal setting Keep submitted command selected leaves a sent command selected in the input. Enter sends it again, while typing replaces it. Password input is always cleared.

Client Commands

Commands beginning with / are handled by PlayMUD.online before aliases and before anything is sent to the MUD.

/help
/print_var gmcp.Char.Vitals
/pv batclient.vitals
/?

/help lists available client commands. /print_var, /printvar, and /pv print readable GMCP, BatClient, state, variable, or settings data in the current terminal.

Fonts And Size

Terminal font and font size are configured separately for desktop and mobile. Desktop Settings can edit both profiles; the mobile More view edits the mobile profile directly.

Font choices are safe monospace presets available on the device. If a selected font is not installed, its configured fallback is used. Sizes are limited to 5-24 pixels to keep terminal controls usable.

Backgrounds

If your PlayMUD.online site has terminal backgrounds available, Settings lists them by name. Pick one and choose an opacity to place it behind terminal output.

The saved setting stores only the selected background name and opacity percentage. Unknown background names are ignored when settings are saved.

Connection Resume

PlayMUD.online keeps active MUD sessions tied to your profile and selected server. Closing or refreshing the browser only detaches the page; returning with the same logged-in profile resumes the selected server session automatically when possible.

• The latest 200 lines are kept temporarily in server memory and replayed when needed.
• Replayed output is display-only and never launches simple or Lua triggers.
• Triggers do not run while every browser is detached.
• Other active server sessions stream into their own terminal buffers while you view one server.
• Clicking Disconnect explicitly closes the selected MUD server session.
• Logging out detaches the browser but does not intentionally close MUD sessions. Disconnect, account disablement, a MUD disconnect, or a PlayMUD.online restart can close them.

A resumed connection keeps the original MUD server and charset. Selecting another active server makes it visible, restores its scoped client data, and keeps the previous server online until you disconnect it.

Charsets

The charset selector controls how incoming MUD text is decoded before it appears in the browser. Current options include UTF-8, Latin-1, ISO-8859-10, Latin-10, Latin-11, and Windows-1252.
