device driver for the DoubleTalk speech synthesizer

I have updated my kernel driver for the DoubleTalk PC speech
synthesizer from RC Systems. It now works with the latest
developmental kernels (since 2.1.115, at least). A source
package

dtlk-1.16.tar.gz

and a kernel patch against the 2.1.124 sources

dtlk-patch-2.1.124

are available from my web page (http://www.mv.com/ipusers/vanzandt).
I have also uploaded the source package to the blinux ftp site, where
it should be available shortly (ftp://leb.net/pub/blinux/).

I wrote this driver to support emacspeak, which provides emacs with
speech output and thereby makes it accessible to a blind user. It has
been working as a module under 2.0 kernels for over a year now.

I suppose it is too late to get this driver incorporated into the next
"stable" kernel. There would have been plenty of time, except that a
code freeze was announced shortly before I got it working, and I
actually believed it. (Silly me. That was back in January.) On the
other hand, it is unlikely to interfere with any other kernel
functionality - especially for the vast majority of users who do not
enable it.

The 26 kB patch touches these files:

I would appreciate any comments.
