Maybe your other software (speak-up) has control of the port when

Try this:
echo This is a test. > /dev/ttyS0

from the shell prompt.

Also try using stty to set serial parameters on /dev/ttyS0, and if you
think there could be a conflict with speak-up, ask on the speak-up
mailing list.

I have never used speak-up and thus don't know whether it might be
engaged in a conflict here.
