Hi,

I played round with this a while ago on my Ultra10 and had exactly the
same problems.  I tested the modem and line under a different OS as
well as NetBSD x86 and they behaved fine.  As soon as I tried it on 
the U10 I kept on getting this "not 8 bit clean" message.

I tried it on a -current system and also on a 1.6 system where I had
back ported the drivers from -current.  Both times I got the same errors.

I chatted to petrov@netbsd.org about this a while ago and had no 
immediate luck.  He asked for some debugs of the PPP connection but 
unfortunately by that stage my U10 was doing something different and I
never got back to him.

Maybe someone could pick it up from here . . . .

Adrian.
