+## Timeout
+
+By default, PTY sessions have a **60-second timeout** which limits the total duration of the session. When the timeout is reached, the connection will be closed regardless of activity.
+
+For long-running sessions, set `timeoutMs: 0` (JavaScript) or `timeout=0` (Python) to disable the timeout.
+
+<CodeGroup>
+```js JavaScript & TypeScript
+const terminal = await sandbox.pty.create({
+  cols: 80,
+  rows: 24,
+  onData: (data) => process.stdout.write(data),
+  timeoutMs: 0,  // No timeout for long-running sessions
+})
+```
+
+```python Python
+terminal = await sandbox.pty.create(
+    size=PtySize(cols=80, rows=24),
+    on_data=lambda data: print(data.decode(), end=''),
+    timeout=0,  # No timeout for long-running sessions
+)

 ## Send input to PTY
 
 Use `sendInput()` in JavaScript or `send_stdin()` in Python to send data to the terminal.

+### Accessing accumulated output
+
+After reconnecting, you can access all output generated during the session (including while disconnected) via the `stdout` property:
+
+<CodeGroup>
+```js JavaScript & TypeScript
+// After reconnecting...
+const reconnected = await sandbox.pty.connect(pid, {
+  onData: (data) => { /* handle new data */ },

 ## Kill the PTY
 
 Terminate the PTY session with `kill()`.
