I recommend kernel ppp when acting as a dial-up server.
Works well for me.  

% tail -6 /etc/rc.local
echo -n 'starting local daemons:'

pppd ttyd0 persist
echo -n ' pppd'

echo '.'
% cat /etc/ppp/options
crtscts
proxyarp
netmask 255.255.255.0
proust-ppp:compound
domain think.com
#passive
persist
modem
%

I also put in a crontab entry...

proust# crontab -u root -l 
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.466 installed on Fri May 10 13:13:02 1996)
# (Cron version -- $Id: crontab.c,v 1.3 1995/05/30 03:47:04 rgrimes Exp $)
SHELL=/bin/sh
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/etc
HOME=/root

#min	hr	md	mo	wd	cmd
*/5	*	*	*	*	checkpppd
proust# cat /usr/bin/checkpppd
#!/bin/sh
k=`ps ax | grep pppd | grep -v grep | cut -c 1-5`
if [ "X$k" = "X" ]; then
  pppd ttyd0 persist
fi
exit 0

This is because I found that pppd would sometimes fail
to reaquire the device after a hangup, and then would terminate.

Here are the relevant sysconfig sections:

######################### Start Of Netconfig Section #######################

# Set to the name of your host - this is pretty important!
hostname=proust

# Set to the NIS domainname of your host, or NO if none
defaultdomainname=think.com

#
# Some broken implementations can't handle the RFC 1323 and RFC 1644
# TCP options.  If TCP connections randomly hang, try disabling this,
# and bug the vendor of the losing equipment.
#
tcp_extensions=YES

#
# Set to the list of network devices on this host.  You must have an
# ifconfig_${network_interface} line for each interface listed here.
# for example:
#
#	network_interfaces="ed0 sl0 lo0"
#	ifconfig_ed0="inet 10.0.0.1 netmask 0xffffff00"
#	ifconfig_sl0="inet 10.0.1.0 netmask 0xffffff00"
#
network_interfaces="lo0 ix0 ppp0"
ifconfig_lo0="inet localhost"
ifconfig_ix0="inet 198.87.99.30 netmask 0xffffff00"
ifconfig_ppp0="inet 198.87.99.33 198.87.99.34 netmask 0xffffff00 down"

#
# Set to the list of route add lines for this host.  You must have a
# route_${static_routes} line for each static route listed here.
#
static_routes="loopback ppp"
route_loopback="198.87.99.30 127.0.0.1"
route_ppp="198.87.99.34 198.87.99.33"

# Set to the host you'd like set as your default router, or NO for none.
defaultrouter=198.87.99.1

# These are the flags you'd like to start the routing daemon with
router=routed
routedflags="-g"

# If you want this host to be a gateway, set to YES.
gateway=YES

# Set to YES if you want to run gated
gated=NO


I suppose I should turn off routed altogether.  But that would be
draconian:-)  I left out the details of security, so the above
configuration provides a promiscuous dialup.  But this should get
you up, anyhow, and then you can fix the security at your leisure.
