Hi Lee,
Does using TelnetTransport 'will' and 'requestNegotation' work? E.g.
self.will(LINEMODE)
self.requestNegotiation(LINEMODE, '')
I'm not completely sure about LINEMODE, but if the client sends back a
DO, you might use something like:
class MyTransport(TelnetTransport):
def connectionMade(self):
self.linemode = False
self.will(LINEMODE)
TelnetTransport.connectionMade(self)
def commandReceived(self, command, argument):
if argument == LINEMODE:
if command == DO:
self.requestNegotiation(LINEMODE, '')
self.linemode = True
elif command == DONT:
pass
else:
TelnetTransport.commandReceived(self, command, argument)
def write(self, data):
if self.linemode:
# do something special
else:
self.transport.write(data)
Best,
Patrick
