NetDial Overview

Defines the stages of a dial-up connection. Generally connections are started by the comms systems when a TCP/IP socket connection is requested.

Note: the NetDial component is deprecated from v6.1 onwards. The new RGenericAgent API should be used instead.

The Network Interface Manager (NifMan) provides a generic framework for controlling network interfaces, and defines a plug-in architecture. NetDial is such a plug-in for handling dial-up networking. TCP/IP uses NetDial to establish a connection, before setting up the connection with PPP.

NetDial gets comms settings, such as modem and ISP configuration, from the communications database (CommDb). It uses the Telephony subsystem to make the dial-up connection.

NifMan provides an interface to monitor a connection. Its progress information (TNifProgress) contains stage information defined by TNetDialProgress when a NetDial connection is used.
