do you plan on doing anything after dialing, or just dialing and hanging
up? are you seriously asking how to control a hardware device on your
PC to open and manage a network connection -- in a language newsgroup?
Isn't that like asking how to spin up a CDROM drive and read raw data
from it?
first of all, the windows dialer is a very strange beast. It basically
handles negotiating a connection using the modem's device drivers to a
distant modem (handshake, speed, compression, error checking, stuff like
that), and setting up the TCP/IP stack, handling DHCP if necessary, DNS,
etc. It can even torture routing tables and generally make a hash of
things.
generally, the windows dialer is a service that can be automatically
invoked by making a sort of request for network connectivity. There is
a windows API available (RAS API I believe)that has various ways of
talking to windows about its connectivity -- for example, instruct
windows to attempt it's default connection, or simply launch the dialer.
Windows API's would be written in C, of course.
BBS's are usually accessed using a terminal (HyperTerminal), which I
don't think uses either the windows dialer or TCP/IP, but don't quote me
on that. It just uses windows API's for accessing the modem hardware.
Software fax machines dial fax modems, etc.
Not for the faint at heart.
