CHAPTER 7
Routing and Communications7
The Newton system provides a standard user interface for sending and
receiving data by several communications methods, called transports. Most
Newton systems come with transports for printing, faxing, beaming, and
e-mailing. You can develop additional transports that users can install and
remove at will, independent of installing and removing applications. The
system makes newly installed transports available immediately in all
applications, built-in and otherwise, and makes newly removed transports
unavailable immediately in all applications.
If you are developing an application and want to give users access to
transports for sending your application’s data items, you include Action
buttons in the application’s container views. If you want your application
to receive incoming data items, you have your application tell the system
which types of items it can handle. The rest of the user interface for sending
and receiving data items is provided by the transports, the system, and the
built-in In/Out Box application.
This chapter describes the Newton routing and communications interface in
detail, covering the following topics:
■What role the In/Out Box application plays in routing incoming and
outgoing data items
■How users route outgoing items, including how the Action button works
and how transports get routing information from users
