About the PPC Toolbox

The PPC Toolbox provides you with the ability to

• exchange data with other open applications on the same computer or across a network of Macintosh computers
• browse through a listing of applications that are available to exchange data
• verify user identities for communication across a network

To utilize the PPC Toolbox to exchange data between open applications, each application involved must support the PPC Toolbox.

This chapter first defines the main elements of the PPC Toolbox and then discusses how to

• set up your application for communication
• use security features prior to establishing communication
• locate other applications that can exchange data
• initiate communication between applications
• accept or reject incoming communications requests
• transmit and receive data between applications
• terminate communication between applications
