I have a C program that I've been using for quite some time now
which maintains a SLIP connection, detecting hangups and redialing
when necessary.  It can also be run from rc.local, which I do.
It works perfectly with NetBSD-current.

I wrote it because I'm often away from my machine, but need to
access my machine reliably.  This allows my machine to slip right
back in automatically even in the event of a crash, power failure,
or disconnection.  It is quite robust and never gets "stuck".

Unfortunately, it is not general-- it is specifically coded to call
the system here at brown, which dynamically assigns IP addresses.
However, the code is fairly well organized, and should be easy to
modify for whatever system you use.  It also keeps a log of everything
that happens, and can be configured to log various amounts of
information; even the entire session, which is useful for debugging.

In any case, anyone who wants the source can have it.  Someone else
might even have the patience to carve it into a more general tool.
