Re: dual CPU system hangs

Chris,

If you're using a G4 tower (which seems to be the case, since it's a dual proc 
machine), you'd be better served by a product called "Stealth Serial Port" (or 
something like that).

It turns your modem port into a serial port.

It's discontinued for a long time, but maybe you can get one on eBay.

That's what I use on my blue and white G3 so I have a serial console. The best 
part is that you'd only need to set the input and output devices through 
OpenFirmware and be all set! It's simple as that!


Cheers,
Flavio
