How do I make backspace work in 'vi' with PuTTY like it did with SSH?

With the default settings in PuTTY, the backspace key acts as delete in 'vi'.

To make the backspace key actually backspace in 'vi' with PuTTY:

• open PuTTY
• highlight Default Settings in the Saved Sessions area and click Load
• click Keyboard under Terminal in the Category (left) pane
• set the Backspace key to send Control-H instead of Control-?
• click Session in the Category (left) pane
• highlight Default Settings and click Save

You can apply these steps to any other Saved Sessions you have set up.
