driving a serial synthesizer through speech-dispatcher

[John Covici]

You can treat the serial port like a file (this is linux after all),
just do open in the i nit section and write characters to the file.
The name will be something like /dev/ttyS0 or similar.  Note the
capital S.  As an example look at the espeak  driver, so you get all
the things in the right places.
