# Serial

## Introduction

The **Serial** **Nodes** allow the user to connect to serial devices -- like GPS devices -- via USB or serial ports using *Serial* *Communication*. *Serial* *Communication* sends single bits of data at a time, sequentially, through a communication channel/bus. To use the **Serial** **Nodes** in **Incari**, the user first needs to locate the [**Serial Attributes**](/incari-studio/modules/project-settings/serial.md) in **Project** **Settings** and add a `Connection`.

This form of **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 render the **Serial Nodes** unavailable. Please refer to the [**Plugins Editor**](/incari-studio/modules/plugins.md) to find out more information.

### Serial Guideline

These are the guidelines for incorporating **Serial Communication** into a **Project**.

* To properly start a connection, see the [**General Guideline**](/incari-studio/toolbox/communication.md#general-guideline) on the Communications Introduction page.
* Once the connection has been established, there are several **Nodes** that cover important functions of **Serial Communication**.
  * [**On Serial Error**](/incari-studio/toolbox/communication/serial/events/onserialerror.md) executes when an error is received.
  * [**On Serial Packet Received**](/incari-studio/toolbox/communication/serial/events/onserialpacketreceive.md) executes when a **Serial** data **Packet** is received.
  * [**Serial Send Packet**](/incari-studio/toolbox/communication/serial/serialsendpacket.md) sends a **Serial** data **Packet**.
* To properly stop a connection, see the [**General Guideline**](/incari-studio/toolbox/communication.md#general-guideline) on the Communications Introduction page.
