Thanks for the clues. If possible anyone with clues about setting the
MTU and MSS settings would have my deepest gratitude.

There are two things that I can think of.
1. Timing -- You say that if you step through in the debugger, it
tends to work. Try putting a delay into Mac OS 9's initial response.
2. Packet different -- Capture packet traces for the first packet
from Mac OS 9 and the first packet from Mac OS X, and diff them.
There should be noticeable differences. Try to eliminate them. The
trickiest one is that Mac OS 9 sets the "do not fragment" bit on all
packets as part of its path MTU discovery algorithm. There are ways
to disable this. You'll probably find some hints in the list
archives.
