This is a simple tip for PuTTY Configuration.
When you first use PuTTY , you will find the cases that BACKSPACE would not work and showing as strange sequence of ^ and question mark (^?^?^?) for some UNIX servers.
You can fix this problem just by changing the setting. Select Terminal Keyboard at the left TreeView control of the main PuTTY screen and select Control-H instead of default Control-?(127).
Also make sure you save the settings.
