Re: Serial family IOkit questions

Ultimately you're limited to the baud rates supported by the device. You might want to contact Keyspan to find out what baud rates they can deal with.


Yes, but that's "Ultimately", given that particular Keyspan device. I'm talking about "Theoretically", given the overall Serial family IOkit, and the fact that it locks out those baud rates, and that combinations of baud rate settings do really unusual things.

Given the most infinitely capable USB device, or any arbitrary serial port under OS X, it looks as if there are, er, unusual restrictions.

I have no problem with buying any other USB serial adapter you can recommend for my Powerbook. I've also got a PCI based Mac, if you can recommend any PCI serial adapter that will skirt these problems then I'll buy one of those just to see how it works. If there's any available new from Apple Mac that addresses this, let me know.
