# On Serial Packet Receive

## Overview

![The On Serial Packet Receive Node.](/files/wncYko0kuKuqHoLJMbX7)

The **On Serial Packet Receive Node** is an **Event Listener Node** that executes when a data **Packet** is received and returns its `Message`.

**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 Packet Receive** will not show up in the [**Toolbox**](/incari-studio/2022.2/toolbox/overview.md). Please refer to the [**Plugins Editor**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2022.2/toolbox/modules/plugins/README.md) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2022.2/toolbox/communication/overview.md#scopes): **Project**, **Scene**.
