DtCallbackMenu

This example shows how to register for a VR-Link interaction (in this case the comment interaction) and can pass that information to the front-end via an event signaler.

This example is an example of a protocol dependent example.

This example will show how to:

• Add a menu and menu item to the system
• Adds an accessory which will allow for interaction with the exercise connectipn
• Shows how to to send protocol specific data to the protocol independent side of the front-end via the network interface protocol
• Shows how to send a signal from the protocol independent front-end to the protocol dependent accessory to send the interaction
