I can only speak from a debian perspective, and I am no expert but I'll spew 
forth what I can remember.

There are two scripts pon and poff to connect and disconnect the dialup.

Confs are found in /etc/ppp/*

/etc/ppp/options contained the following options when it was working for me
   asyncmap 0
   auth
   crtscts
   lock
   hide-password
   modem
   proxyarp
   lcp-echo-interval 30
   lcp-echo-failure 4
   noipx


/etc/ppp/pap-secrets holds the login detail thus
   "username" *       "password"        *

/etc/ppp/peers contains scripts for each of your isps. The default script is 
called provider and you need make an edited version for your isp.

for example /etc/ppp/peers/clear
   # This optionfile was generated by pppconfig 2.3.10. << there's a hint
   #
   #
   #hide-password
   noauth
   connect "/usr/sbin/chat -v -f /etc/chatscripts/clear"
   debug
   /dev/ttyS0
   115200
   defaultroute
   replacedefaultroute
   noipdefault
   user "username"
   persist
   usepeerdns

/etc/chatscripts/clear looks a bit like this
   # This chatfile was generated by pppconfig 2.3.10.
   # Please do not delete any of the comments.  Pppconfig needs them.
   #
   # ispauth chat
   # abortstring
   ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO \
   DIALTONE' ABORT 'NO ANSWER' ABORT DELAYED
   # modeminit
   '' ATZ
   OK "AT S7=45 S0=0 L1 V1 X4 W2 &c1 E1 Q0"
   # ispnumber
   OK-AT-OK "ATDT086725327"
   # ispconnect
   CONNECT ''
   # prelogin
   # ispname
   #ogin: "username"
   # isppassword
   #ssword: "\password"
   # postlogin
   '' \d\c
   # end of pppconfig stuff

Some of that may well be unused dross that found it's way in there while trying 
to make it work which did take me a full week.

As I say, this is all debian stuff and is unlikely to apply to Suse, but the 
defaultroute, replacedefaultroute and usepeerdns directives in the 
peer/provider script look a bit relevant to yuor problem.

I don't think I ever had it working from userland.
