You're a genius!!! He's a genius!!! Success!!! I can confirm this does
work with a Keyspan USA-28 running in Classic, using Newton Connection
Utilities and connecting to a MessagePad 120 v2.0!

Just for fun, I tried to see of I could use my Keyspan USA-28 with the
various drivers you pointed out. It pretty much went like you said. I
experienced the crash and Classic shutdown. I unplugged the Keyspan
device, restarted Classic and launched NCU, the Keyspan device then
confirmed it was connected at 115,200bps!

Some notes on using the Keyspan device in Classic:

1) Maximum speed for the Keyspan USA-28 is 115Kbps according to the
tech specs. So, you will need to install the Serial 115200 enabler
package (not the 230400 enabler) on your Newton.

Download here:
   http://www.ee.cityu.edu.hk/~clli/unixnpi/Ser115200.pkg.gz

2) The Serial Enabler control panel is set to 38400 locked to 115200.

3) Use the Printer port (Port 1) on the Keyspan device and set the
Keyspan Assistant control panel settings to "Emulate Printer Port"

Yes, I used to use AppleTalk on OS 9 as the connection protocol. Always
got decent speeds. But since moving to a PowerMac G4/500-AGP and OS X,
AppleTalk is no longer supported and I've had to set NCU & NBU to
connect using serial through the KeySpan adapter.

No need, it does work! I'll bet 230400 will work too with the right
RS-232 cable, as you mentioned. I'm testing an 8MB backup right now and
I'll give some rough calculations as to the speed boost at 115200,
later today or tomorrow.

We should set up a wiki page with this information. I (literally)
believe this is a breakthrough. We should also upload the software
drivers to UNNA.

Thanks again, your information was absolutely fantastic!
