+ I doupt it. I'm not using PPP at all and I've noticed the same

I noticed the same difference between Solaris and SunOs. However, the
SunOs host is an old sun4 while the Solaris host is a dual processor
sparcstation. Using the same connection with trumpet windosock gets
comparable performance from both (so it's not the line or connection;
and certainly ms-windows 3.1 is not exactly an operating system
suitable for slip connections; I get overruns all the time even with
a 16550, something I still haven't ever seen in linux where slip
processing happens inside the kernel).
