PPP Dial-in Server

[Stephen]

This involves a lot of info so perhaps some pithy writing will help.

The related hardware:
-FreeBSD 4.8-stable computer with a 56K Best Data external modem and a
NIC to my LAN
-Windows 2000 computer with a 56K internal modem

Goal:
Dial-in from the Windows box to the FreeBSD box from anywhere with a
phone line, be able to access my LAN, and get on the Internet through my
broadband connection

I have:
-Followed the handbook section on serial communications Dial-in service
(17.4) up until programming the modem because I couldn't find the
correct commands
-Installed mgetty+sendfax since I couldn't program the modem myself.

I can:
-Connect from the Windows computer when I choose to have a terminal
screen displayed.
-Log in at the prompt as if I was sitting right in front of the FreeBSD
box.

I cannot log in without getting the terminal screen first under windows.
It says a PPP session couldn't be established because the remote
computer wasn't responding.  It tells me to use the terminal window.  I
went through all the 18.2 handbook info about setting up a User PPP
dial-in server but I'm really not sure what parts I need and what parts
I have to choose one thing over another and what parts I can skip.  In
general I find the whole section confusing. I tried several times
working with all the various ppp config files but no go.  

Is it possible to do what I am trying to do?  Would anybody care to
recommend a more clear version of what the handbook has?  Do you
recommend I try to dial-up with another FreeBSD computer first before
trying to bring Windows into this?  Thank you for taking the time to
read all this and for helping me out.
