The AppleTalk Remote Access API provides an application programming
interface to the Remote Access Manager. It supports calls to load and
unload the Remote Access Manager (RAM), create and terminate
connections, retrieve the current RAM status, and to determine if a
specified network address is local or remote. Optionally, the
AppleTalk Remote Access API can display a user interface showing the
process of a connection. The parameters for the connect call can be a
connection document, created with the Remote Access application, or
all the parameters of the connection can be specified out right. These
specifications also include how to tell if AppleTalk Remote Access is
installed, and how to deal with the serial port when AppleTalk Remote
Access is in answer mode.
