I have tried to turn off echo back from the server but it still receives the data sent to the server.

none of the following options has turned off echo:

Telnet tn = new Telnet();
tn.Echo = OptionState.RequestOff;

tn.ServerOptions.Add(new Option(OptionCode.Echo, null, OptionState.RequestOff));
tn.LocalEcho = false;

Is there some other option that will turn off echo back from the server.

I've just tested this and we are sending the correct commands, but some servers do not respect the client's request to disable server echo. If you have a third-party application or control that is disabling server echo on your server please post the client software details and the server software name and version, and we will investigate further.

To most easily modify server echo while connected to your server, set the Telnet.Echo property. To force the option to be sent during initial negotiation, set the option in Telnet.ServerOptions.

If you explain your usage scenario we may be able to provide some recommendations to enable your desired behavior.
