echo in console connection

Question

I use pyserial in python to connect to cisco console port:

>>> import serial
>>> console = serial.Serial('COM5')
>>> console.read(console.inWaiting())
''
>>> console.write('sh ip inter brie\n')
17L
>>> console.read(console.inWaiting())
'sh ip inter brie\r\nInterface                  IP-Address      OK? Method Statu

It works good except there is echo in reply. Is there a way to disable it?

Answer 1

Finally i found that cisco is buggy with serial echo switch off. The function doesn't work. Putty manage incoming text row and modify it to make it look as we want to see

Thus there are two possible solution:

1. Manage incoming text row as putty does
2. Use putty-like apps if it is possible
