Chilkat SSH commands shows in output

Hello, I would like to get rid of the commands I am executing on device. I have Windows user form and when I am sending commands to the switch in the output except the results or action which the application did on the device I also see commands / config. I want to get rid of them and show only result of these commands.

            /*THIS IS THE SET OF COMMANDS I WANT TO RUN */
            ssh2.ChannelSendString(channelNum, command, "ansi");

            if (success != true)
            {
                if (x < 2)
                {
                    output_box.Invoke((MethodInvoker)delegate
                    {
                        // Running on the UI thread
                        output_box.Text += "\r\n Execution of commands failed \r\n Running again ...\r\n";
                        tofile += "\r\n Session failed \r\n Running again ...\r\n ";
                    });
                    x++;
                    i--;
                    continue;
                }
            }

            ssh2.ChannelSendEof(channelNum);
            var cmdOutput = ssh2.ChannelReadAndPoll(channelNum, 2000);
            var result = ssh2.GetReceivedText(channelNum, "ansi");
            tofile += result;

            output_box.Invoke((MethodInvoker)delegate {
                // Running on the UI thread
                output_box.Text += result;
            });

So what I see in the output_box is this -> how do I get rid of the first four lines starting with ,,conf t" and ending with ,,end"

############### SWITCH ##################### - 1 of 2

conf t
vlan 20
name 20
end

SWITCH# conf t

Enter configuration commands, one per line. End with CNTL/Z.

SWITCH(config)# vlan 20

SWITCH(config-vlan)# name 20

SWITCH(config-vlan)# end

SWITCH#
