driving a serial synthesizer through speech-dispatcher

[Gregory Nowak]

Thanks to everyone for all the input so far. I didn't realize that
some of the modules with the .conf files also have binaries as the
backend. I do indeed see that they're there in
/usr/lib/speech-dispatcher on my system. I'll have to look at the
speech-dispatcher code, and see how they do what they do.

I'm still in favor of letting speakup drive the serial synth. Thanks
to Samuel's comment below, I know what part of the speakup code to
look at, and the comment that it should be a fairly simple beginner kernel
hacking project is encouraging. I'll add this project to my to do list,
and will explore it once I have more time, hopefully sooner rather
than later. Thanks again.

Greg
