[Twisted-Python] Telnet & echo

[Michał Tyde]

I try to find a solution on google, but nothing I have found there
worked in my code. The situation is:
I have a telnet client. When I am sending a command to a server my
dataReceived loop gets a command I send and response. For example I send
a "pwd" command, and in dataReceived i got:
pwd
/home/user/
I want to have only response.
I try to send before sending command IAC WONT ECHO or send command
"unset echo" but I have still a command and response in dataReceived.
How to shutdown echo?
