I assume that your modem is on ttyS1?

>From the pppd man page:

       noipdefault
              Disables the default behaviour  when  no  local  IP
              address  is  specified,  which  is to determine (if
              possible) the local IP address from  the  hostname.
              With  this option, the peer will have to supply the
              local IP address during IPCP negotiation (unless it
              specified  explicitly  on the command line or in an
              options file).


Thus 'noipdefault' does not override addresses in options files.  Comment
out the addresses in options.ttyS1.
