Hi Érico, this command works for me with the latest Octave and
communications packages, so you are likely seeing a bug that has been
fixed in a newer version of one or the other.

I do not have a setup with your version of Octave so I haven't
verified this will fix it for you, but you can try installing a newer
communications package by downloading it from
http://octave.sourceforge.net/ and installing it with

pkg install communications-<version>.tar.gz

in the Octave shell.  If this doesn't work for you, then your version
of Octave may be too old for the newest communications package and you
may need to upgrade both together.  I use Debian, I don't know if
Ubuntu has newer versions of these packaged that you could apt-get on
your system, others on the list may know.  I hope this is enough to at
least get you started.
