### **In This Guide**&#x20;

you'll learn how to connect to a **GrowSpace Gateway** using **Tera Term** to check serial logs and send commands.\
We’ll walk through each step—from what Tera Term is, to how to install it, set up the necessary drivers, and establish the connection.

***

### What Is Tera Term?

**Tera Term** is a terminal emulator that allows your PC to connect to devices via **serial communication**, making it easy to check logs and send commands.

With **Tera Term**, you can directly access key information from the **GrowSpace Gateway**, such as:

* MQTT broker connection status
* Network settings and error logs
* Device configuration values
* Real-time debug messages

It's a simple and powerful tool for both developers and system operators, allowing quick status checks without the need for a full development environment.
