Testing a synthesizer

[james collins]

I tried this command at the command line. When I ran it my cursor  
moved down a line and I was able to type words and then I would hit  
return, but my doubletalk wouldn't talk. I am trying to test my  
doubletalk synthesizer. I bought a USB to serial adaptor cable, I am  
using it with a doubletalk speech synthesizer. Just wondering why I  
can't get my doubletalk to talk? Any help would be appreciated.

The command would be:

echo "text" > /dev/ttyS0

...but the hal daemon might get in the way.
