First, thank you a million times over fbsd_user! This has been bugging
me for a LONG time. Quite kind of you to include all that information.
Following the advice below and with some additional info I am able to
dial in, although I haven't gotten to the routing stuff yet. Some
things I found that might be helpful to someone else:

I found the /etc/gettytab file had to specifically be as follows:

default:\
        :pp=/etc/ppp/ppplogin:\
   then the rest here......

In other words, adding the pp line to the end of the default section
didn't work for me.

My bare minimum /etc/ppp/ppp.conf file contains only:

default:
 set log Phase Chat LCP IPCP CCP tun command
 set speed 115200
 set timeout 180

incoming:
 allow users xxxx xxxx xxxx
 enable chap #will use ppp.secret
 set ifaddr 10.0.0.1 10.0.0.74 255.255.255.255

I also issued the following commands for my modem:

cu -l cuaa0 (use your appropriate number, cuaa1, etc)
ATZ
ATS0=1 (the 0 is zero, 1 tells modem to pick up on first ring)
AT&W
~.

And then:

ppp
ppp on yourcomputername > set device /dev/cuaa0
ppp on yourcomputername > set speed 115200
ppp on yourcomputername > term
AT
AT
~.
ppp on yourcomputername > quit

I discovered the necessary modem commands on the mailing lists while
googling. On to the the routing...
