# Entwickeln ohne ein Board

Wenn Sie die „Server“-Seite entwickeln und den Code ausprobieren möchten, können Sie ihn ohne Hardware ausführen, indem Sie über ein Null-Seriell-Terminal verfügen. Führen Sie dazu in einem Terminal Folgendes aus:

```
python resources/demoSerial.py
```

dann in einem anderen Terminal ausführen

```
python relayekeysd.py --noserial
```

Hinweis: Nur unter MacOS getestet, sollte aber auf jedem Posix-System funktionieren. Geben Sie für Windows einfach einen COM-Port an, der nicht existiert.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.acecentre.org.uk/products/relaykeys-german/developers/developing-without-a-board.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
