Trying to experiment with my overclock settings.  Ant had been OC to 400 before by previous owner. 

I can ssh into the ant on both linux & windows (putty), I can login, edit the file but cannot seem to quit and save.

I press esc after editing, w then q.  I then get a message "q not implemented" I am then unable to exit the session and have to close the terminal.

Any suggestions please?
