# Page-Control

If the device supports paging (see [OPTIONS](/extending-and-apis/serial-connection/device-communication-flow/device-config-phase/device-options.md)), the current page being active can be controlled from the device

## SWITCHPAGE: Switching to a specific Page

Syntax: `1,SWITCHPAGE,<Guid>[,<create>,<name>];`

|           |                                               |
| --------- | --------------------------------------------- |
| \<Guid>   | GUID of the target page                       |
| \<create> | 0 \| 1 , create page if it doe snot exist yet |
| \<name>   | name of the new page                          |
