I have found that a rather simple way to run SLIP is to use the NetBSD 
version of dip (the Linux slip program) that is available somewhere on 
ftp.netbsd.org.  Dip is fairly easy to use and the package comes with 
example scripts which are quickly customizable.  If you actually need to 
use PPP, someone had posted earlier a series of scripts which can be used 
with chat to make a PPP connection.  If anyone wants them, mail me and I 
think that I still have them saved somewhere.

Later,
