I'm not sure about your problem, but thought I would try guessing ;-)

First, what kind of physical connection do you have between your MP (BTW, what model is it?) and your computers? If it's the serial cable that came with the MP, then you must go serial
all the way. You *can't* use AppleTalk. So, you must unchecked AppleTalk in NCU and check or select "Serial". Then, that being said, if you have a fax software on your PowerBook, it
might grab the serial port at boot time in order to be able to receive fax. You might want to check that it's not the case, because if you try to connect from NCU using the serial port,
you will get this message that the serial port is already in use.

You mention your "new G3". What model is it? Starting with the Blue & White G3s, there is no longer a serial port. I'm curious about what the "Stealth" port is, maybe some kind of
USB-Serial adapter? We would need more details here regarding your configuration.

In any case, depending on the physical connection you make between your MessagePad and your computers, you have to pick the right transport. If like I think, you're using the cable that
came with your MessagePad, then you don't have the choice and must use serial. That means that NCU is configured for serial, and that the Dock/Connection application on your Newton is
also configured for serial. Then, if you get a message that the serial port is in use, then it's really the case. There is something on your computers that is grabbing the serial port.
On a PowerBook, that's often some kind of a fax software. But I don't know for sure, so you'll have to check yourself.

Hope it helps somewhat... Give us more details and we might be able to help more.
