title: How can i mask user input when telneting?
body: <p>I have a socket application.  The socket for the client connection uses a NetworkStream which does not allow seeking.</p>
  
  <p>So, how can i mask user input when they telnet to my socket server since NetworkStream does not provide seeking?</p>
  
  <p>1.) It needs to work with 3rd party telnet, ie: im not creating the telnet client
  2.) I can settle for nothing being shown in the telnet client, but prefer masking</p>
  
  <p>Thanks in advance.</p>
