Nonsense. The any Apple serial cable is fine for point-to-point AppleTalk
connections. I do it all the time.

The serial port will also be in use when AppleTalk is switched on and set to
use the serial port you are trying to use for connecting to the Newton.

The Stealth serial port is a small piece of hardware that transforms the
internal modem slot in a B&W G3 into a standard MiniDIN-8 serial port. The
internal modem slot really is a serial port in disguise, and the Stealth
port is very compatible because of this. It should work, many have reported
it working.

Yes. First of all make sure you have no background software that is hogging
the serial ports. On a Mac, I would always go for AppleTalk connections to a
Newt, because it is faster. Turn on AppleTalk, and set AppleTalk to connect
through the serial port. If it complains that the serial port is in use,
there is some software using it. If not, you're all set. Next, fire up NCU,
set it to connect thru Appletalk. Then, fire up the Dock app on the Newton.
Select AppleTalk as the connection method. You should now see you desktop
computer's name in the list of available computers.

One last thing: Mac OS 9 might have removed two extensions that you need for
NCU to operate correctly: Apple Serial Tool (for serial connection) and
AppleTalk ADSP Tool (for AppleTalk connection). You can reinstall these
tools from your NCU disk(s) or download then from Apple's website.
