I have had problems with my 9600EX, calling a Telebit at 9600 with MNP-5.
I also had some problems calling the same system with an old Codex using
MNP-4.  When I disabled MNP, problems went away.

My best observation is simply "it happens when there's a lot of data
movement, especially when I'm receiving."

I'm wondering if there might be a buffering problem somewhere, maybe in
the Telebit, maybe not.  I only lost connection a few times with the
Codex, each time during a big ASCII printout.  WIth the 9600EX, it was
happening all the time.

So, there's my 2c.
