### Enable MODBUS RTU Service on Xatellite

Source: https://docs.esix.co/application-note/other/modbus-rs485

This snippet demonstrates the configuration steps to enable a MODBUS RTU service on a Xatellite device via its web administration interface. It involves navigating to the RS485/ModBus section, adding a new service, and ensuring the 'Enabled' checkbox is selected. The serial device is typically set to '/dev/ttyCH9344USB0'.

```text
