Suppressing Terminal Echo (General questions)

Hi,
I've been using your product for a long time. It's been working great! I am currently trying to suppress the echo of characters that I send to the ssh Server. For example, if I send the command ls , the first line of the response from the server is ls .

From reading the documentation, the simplest solution would be to set AllocatePty = False, but this causes the connection to fail. Any other suggestions? Is there a different TerminalType (besides vt100 ) that suppresses the echo?

Thanks,
Jon
