This is my setup for PuTTY to connect to my Linux machines.
Terminal > Keyboard:
– The Function keys and keypad = Linux
Window>Translation:
– Character set translation on received data = UTF-8
– Adjust how to PuTTY handles line drawing character = Use Unicode line drawing code points
Connection:
– Sending of null packets to keep session active = 60 # to avoid disconnection from server because of inactivity
Connection>Data
– Terminal Details – Terminal-type string = linux
The other parameter seems to work fine by default.
