I hope the following could be a help to some FreeBSD users.

<<< USER PPP (a.k.a. iijppp) >>>
The following is a working example of a simple configuration of
user ppp (a.k.a. iijppp):
N.B. Most of these are adapted from FreeBSD handbook.
N.B. The deivice for iijppp is tunN (tun0,...) and is built-in
in the generic kernel. No need to recompile or reinstall kernel.

NOTE: 1) Reboot when necessary.
2) After dialing into your ISP, do not shell out from "PPP ON ...>"
prompt. Just leave it as it is.
Use another tty (<Alt><F2> keys) if you are on charater terminal,
or use another window if on x-window.

<<< KERNEL PPP >>>
The following scripts have been working fine on my FreeBSD box at home,
for ppp connection. Most parts are collected from FreeBSD, and kermit
sites, with only a small portion of my own modifications.
I have had no problem using it for ppp connection with my ISP.
My bet is that it should work with your FreeBSD box with little
modifications.
Assumptions:
1. Your kernel has been configured and recompiled with ppp0 device
enabled. Otherwise, you have to recompile and install your kernel
with ppp0 device enabled.
2. You have pppd program installed.
3. You have kermit program installed.
(Kermit is my favorite dialup program :-) working with ppp)
(It is the most reliable/flexible dialup package for me, at least.)

MISCELLANEOUS STUFF:
Note 0:
Reboot if necessary.
Note 1:
Make a symbolic link (/dev/modem) to your real modem device:
# ln -s /dev/cuaaN /dev/modem
(Replcae N with 0, 1, 2, or 3 depending on serial port number
for your modem device.)
Effect:
/dev/modem -> /dev/cuaaN
Note 2:
Enable execute permission for the following files:
/etc/ppp/pppdial
/etc/ppp/pppup
/etc/ppp/ppptest
/etc/ppp/pppdown
Note 3:
Make some aliases in your .cshrc (.tcshrc) file:
alias pppdial /etc/ppp/pppdial
alias pppup /etc/ppp/pppup
alias ppptest /etc/ppp/ppptest
alias pppdown /etc/ppp/pppdown
Note 4:
Reboot if necessary.
USAGE:
How to use the above shell scripts to use ppp:
# pppdial ; dial up your ISP host
# pppup ; activate ppp
......
run your network applications
......
# pppdown ; deactivate ppp and hangup
