Whoa, I'm not sure what happened at the end there.  We've jot a jumbled

All of the above are modem/phone line problems, not a FreeBSD problem. 
If the line is good you'll get a good connection, else you won't.

Bad phone lines are pretty common in bigger cities, and bad modems are a
more common problem.

They both look fine.  I'm running SLIP to connect home to the office,
and I regularly get uptimes of 3-4 weeks coming to the office (~1 mile),
but we rarely get > 24 hours to the ISP across the street.  It's all a
matter of how good the lines are from the remote to the server.

It means that the sliplogin process existed abnormally, rather than
normally.  Something bad happened (like the line went down
unexpectedly).

I *suspect* all of your problems are due to modem setup and/or phone
lines.
