How to not echo what the user types?

[Edward C. Jones]

I am trying to use Octave from Python using the "pexpect" module. In 
Octave, everything that come in via stdin is send right back out via 
stdout split into lines with some CNTL-H's added. This is done so the 
interactive user can see what he is typing. It would be much easier for 
me if this echoing was suppressed. Can this be done?
