Which nos for Slackware 4.0

[Anonymous]

I am about to install Slackware 4.0 on a P200 machine and move away from my
dos based jnos.  Can anyone tell me the best way to implement nos under
linux.  I notice tnos is common but is it the best route.  I am running ip
only with kiss eproms in standard tncs.  No netrom.  I handle nntp and
mail.  Any advice 
welcome as I don't want to end up configuring a system several times just
to get a good nos version.
