3Com Impact IQ Non-connects

I've got two clients that cannot connect with 3Com Impact IQs. Both
clients are getting anxious about this, and if I can't fix this soon I may
lose them.

I posted the 3Com low level trace last Friday (I know, it was a holiday),
and to this list on Monday, and have heard nothing back. Is anyone
looking at this? I just need some idea that someone in Livinston support
is looking at this so I can pass *something* back to the clients.

FWIW: the 3Com Impacts were able to connect for a while. It is hard to
say, but I think they lost the ability to connect was when I enabled OSPF
to add another class C for subnetted ISDN LAN dialup.

The last messages from the 3Com low level trace is below. I also tried to
capture a low level trace of a connect attempt from the PM3; it is below
also. It is hard to tell if I've properly captured the failed connect
session from the low level trace.

Can anyone decipher from this some idea of what is going wrong? Thanks
much,
