Ok, probably a stupid question no doubt but did you disable that damn 16550UART FIFO buffer chip? That's found under ports in the device manager under System Settings in Windows XP, no idea where you'd find it under Vista.

Hi everyone
About a week ago David Truong asked me to test my doubletalk lt with the keyspan serial adapter in fusion. Here is what I've found: I can confirm that output through the hardware synthesizer seems to be garbled and disjointed, though it is somewhat intelligible. I'm trying to track down what's going on, I suspect it could be an issue with handshaking and/or baud rates. Time to dig deep into Windows serial settings--ah, reminds me of the old dialup days. I don't have a dedicated Windows PC, if I did I would be able to determine if it's something going on with Fusion or with the serial adapter, or possibly the combination of the two. That being said, I don't intend to get a Windows PC just to test this, and don't feel any great need to install Windows via bootcamp. If anyone has a windows Pc, the Keyspan USA19HS adapter, and a hardware synthesizer could you please run a test by hooking up the hw synth to the serial adapter and let us know your results, and also what hardware synthesizer and screen reader used? I'm testing with a doubletalk lt using window-eyes 6.1, and I believe David has a Keynote SA, if I'm remembering correctly that is. If I'm right about the keynote SA, is it an older or a newer model? The older models ran at 38400bps while the later models run at 9600bps as the doubletalk does. I'm interested in tracking this down, as the combination of Linux and fusion with this serial adapter doesn't seem to cause any odd results at all--the synthesizer works fine in Linux.
