[Twisted-Python] How to write a simpletelnet client?

Sorry that i answer so late (busssy week).

Switching off ECHO i realized by sending a commands:

unset PS1 (switching off prompt)
stty -echo (swiching off echo)

I don't understand how You want to "inject" commands. Now I used a
defers to handling a commands (sending and getting answers).
dataReceived is responsible for collecting what is comming to Your
client as answer.

This is the factory now i used to connect (maybe thiss will help You):

class MyFactory( ClientFactory ):
    protocol = TelnetProtocol
    '''all printouts from this class will have F at the beggining - form
Factory and they are green - <g>'''    
    def __init__( self ):
        print "<g>F __init__"
        self.protos={}
        self.nextName = None
        self.t0 = time.time()
        
    
    def buildProtocol( self, addr ):
        print "<g>F buildProtocol"
        p = self.protocol( self.nextName )
        p.factory = self
        self.protos[self.nextName] = p
        self.nextName = None
        return p
    
    
    def getClient( self, name ):
        print "<g>F getClient"
        t0 = time.time()
        while True:
            try:
                return self.protos[name]
            except KeyError:
                reactor.run( 0.1 )
        print name
        print self.nextName
        while name not in self.nextName:
            reactor.iterate( 0.1 )
            if time.time() - self.t0 > CLIENT_CONNECTION_TIMEOUT:
                raise TimeoutError, "Timeout on connection"
    
    def addActive( self, proto ):
        print "<g>F addActive"
        self.engine._storeClient( proto )
