[NTLK] Connection woes!

Update.  The Macbook OS X attempt seemed most promising, so I continued messing with it last night.  I abandoned the control panel network settings as suggested.  Making sure that the Keyspan serial port 1 was selected in Newton Connection and "serial" was chosen in Dock, I'm actually able to get it to connect about 15% of the time, just for 60 seconds or so.  I've successfully transferred a few very small packages, but the connection always times out on the Newton side during package transfers of larger than 80K or so.

Once the connection has failed, I have to embark on an arduous reset process, in order to try to reestablish communication.  This involves rebooting the software, rebooting OS X, unplugging the Keyspan, and restarting the Newton.  I'm not sure what the magic combination is, but eventually I can get them to talk again, for just a minute or so before it times out again.

I suspect the problem may be in Newton Connection.  Because the Newton itself tells me the connection has timed out, but the OS X side never notifies me, it may be hanging.  Combine that with the fact that the software freezes when I go into preferences and attempt to make changes to the serial port it uses.  I'm wondering if it's my intel book or Snow Leopard that is the issue.  Has anyone had similar experiences?
