Write your reply.

assistant: Richard Town wrote the following to Craig Ford, and I quote (in part):
What FUD Richard? K56Plus and V.Flex/2 do not interoperate period.
Lucent is the first vendor to supply server chipsets that actually implement
K56Flex. -Every- other K56???? vendor is in the process of upgrading.
Call it what it really is, a scramble to catch up.
Why were -all- of the problems with Rockwell-based clients?
No.
How do I know anything?
I am aware of what SG16 is up to.
Nope, the others are implementations/adaptations.
Why _don't_ you?
Not worth responding to.
It is not I.
What specific problem?
I connect with modems from sundried vendors around the world on a continual
basis, and have tools beyond internal modem diagnostics to evaluate such
links. If there were significant interop problems, I would see them.
Regards....
