That FAQ is out dated. All those modem options are pre set
in any modem newer that 1995. The only thing you have to
do is tell your modem you want it to answer incoming calls.
You do that with Hayes 'AT' commands.
The command you want to use is 'ATS0=1' this tells the modem
to answer on the first ring. In FBSD the way to do this is
to use the built in program 'tip com2'
Use ~ followed by CTRL key plus 'D' key at same time to exit tip.
FBSD has 2 different software packages to service dialin calls,
kernel ppp and user ppp. Kernel ppp is the original software
package to provide this function. It is very hard to debug and
has lost it's usefulness since user ppp came along. User ppp
seems to be the preferred software package for connecting FBSD
to the outside world now a days mainly because it's actively
supported getting buds fixed. Now as in most things documented
in FBSD, user ppp only had to meet the FBSD documentation
standard of the bare minimum. Many users of FBSD feel this
standard is totally inadequate, but we have to live with what we
have. I have been down the same road you are now traveling, I
only found snippets of information here and there that I had to
put together with trial and error to get it to work. So to short
cut this problem for you, here is my user ppp ppp.conf file with
comments you can follow to get your self up and running.

##
# /etc/ppp/ppp.conf File for dial out modem to ISP and Dial in modem for
# connection to this FBSD system.
# Written by Joe Barbish 12/10/2001
#
# This is a working ppp.conf file I use to dial in to my ISP, and to connect
# my Win98 box by dialing in to this FBSD box and accessing the internet.
# There are options in this ppp.conf file that I do not use, But present
them
# here for you to turn on by un-commenting the statements to meet your
needs.
#
# For Nic to DSL configuration see www.daemonnews/200101/pppoe.html
#
# This ppp.conf documentation is based on a fresh install of FBSD 4.4 with
# all file content as delivered with no user changes.
#
# As of 1/1/2001 FBSD does not work with Winmodems. Winmodems are modems
# especially manufactured for the Microsoft Windows market and do not have
# dial controllers so they are inexpensive. The dial function is provided by
# driver software which gets installed in to mswindows. A Winmodem driver
has
# been developed for Linux systems 4/2001 and was ported to FBSD around
# 10/2001. The port has been commented to the ports for version 4.5 and the
# package version may also be commented by the distribution date 01/20/2002.
# It's called the Lucent Winmodem driver ltmdm.
#
# NOTE Any FBSD documentation that says that the physical modem has to have
# it's default options profile set to, NO command echo ATE0 and NO results
# string ATQ1 and saved to the physical modems onboard non-volatile memory
# (NVRAM) or any references to using programs tip, kermit, mgetty, or
minicom
# to perform the dial function is obsolete and out dated as of FBSD 4.0.
#
# Setup Instructions.
# 1. Recompile kernel and change pseudo-device tun 1 to tun 4
# GENERIC kernel defaults to 1 and you need 1 tun device for each com
port
# 2. Add gateway_enable="YES" to /etc/rc.conf so dialin connection can gain
# access to internet.
# 3. Since a private internal IP address numbering scheme is used for IP
# addresses behind this FBSD box the -nat option must be included on the
# ppp command that starts the ppp task to dial the ISP.
# NAT = Network Address Translation. Changes your private internal IP
# address to your public IP address that you get from your ISP for
# outbound messages and does the reverse for inbound messages.
# From the command line example ppp -background -nat dialisp
# 4. Using root create file /etc/ppp/ppplogin
# Create file ppplogin with following 2 statements
# #! /bin/sh
# exec /usr/sbin/ppp -direct incoming
#
# incoming is the section label name in ppp.conf to be processed when
# ppp is started by this script's exec command.
#
# This script will be launched by getty when it detects a ppp dialin
# connection attempt. Program ppp belongs to group network, so you have
to
# change file ppplogin group to network and it's permissions to
read/write
# for the owner, read/execute for group, and none for everyone else.
# chgrp network ppplogin # assign file ppplogin to group network
# chmod 650 ppplogin # set permissions
# 5. Change the default section of /etc/gettytab file for automatic ppp
# recognition by specifying the pp capability. Add following to default
# :pp=/etc/ppp/ppplogin:
# 6. Edit /etc/ttys to enable a getty on the port where the dialin modem
# is attached. com2 = ttyd1 find statement like this
# ttyd1 "/usr/libexec/getty std.38400" dialup off secure
# Change off to on to activate. Verify line speed is correct (std.38400)
# This value is defined in /etc/gettytab. After saving edited results
# issue kill -1 1 command to spawn getty. Use ps ax to show active tasks.
# 7. cp /usr/share/examples/ppp/ppp.secret.sample /etc/ppp/ppp.secret
# Edit /etc/ppp/ppp.secret file adding the ID and password for each user
# that is authorized to login to this FBSD box using dialin modems.
# Use adduser to add new users, add them to user group network so dialin
will
# will accept them.
# 8. TESTING Issue command ppp -background -nat dialisp to test
configuration
# Use commands ps ax to see task list. ifconfig -a to see if tun is
running
# netstat -r to see routing. /var/log/ppp.log to view ppp log events
# ps ax to get ppp -background task number & kill -1 number to terminate.
# 9. Once you are done with testing, make functions permanent.
# Dial ISP at FBSD bootup. Add following to /etc/rc.conf file
# ppp_enable="YES"
# ppp_mode="ddial"
# ppp_profile="dialisp"
# ppp_nat="YES"

Subject: Dial-in question
Hi,
I have a problem. I want to make dial-in conection (like internet
service provider).My modem is 14400 external on COM2.
In FAQ I found:
<12.8. How can I enable dialup logins on my modem?
<So you want to become an Internet service provider, eh?
<First, you will need one or more modems that can auto-answer.
<Your modem will need to assert carrier-detect when it detects a
<carrier and not assert it all the time.
<It will need to hang up the phone and reset itself when the
<data terminal ready (DTR) line goes from on to off.
<It should probably use RTS/CTS flow control or no local flow control
<at all. Finally, it must use a constant speed between the
<computer and itself, but (to be nice to your callers) it should
<negotiate a speed between itself and the remote modem.
<
<For many Hayes command-set--compatible modems,
<this command will make these settings and store them in
<nonvolatile memory:
<
< AT &C1 &D3 &K3 &Q6 S0=1 &W
In file /etc/ttys i made shanges
> ttyd1 "/usr/libexec/getty std.57600" dialup on insecure
How I can make my modem to ansver the call, where I must put (in what
file) tis line "AT &C1 &D3 &K3 &Q6 S0=1 &W" and how i must do this.
maybye I don't know something else what I must to know about dial-in
connection making?
and where I can find more about dial-in atoanswer and etc.
