# On Serial Start

## Overview

![The On Serial Start Node.](/files/UfOaoMLpGomguuxmo8EK)

The **On Serial Start Node** is an **Event Listener Node** notifying that the **Serial** connection was successfully established, therefore enabling the user to perform actions on said connection.

**Serial Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **On Serial Start** will not show up in the [**Toolbox**](/incari-studio/toolbox/overview.md). Please refer to the [**Plugins Editor**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2025.1/toolbox/modules/plugins/README.md) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2025.1/toolbox/communication/serial/overview.md#scopes): **Project**, **Scene**.
