A.5.1 What terminal type does PuTTY use?

For most purposes, PuTTY can be considered to be an xterm terminal.

PuTTY also supports some terminal control sequences not supported by the real xterm: notably the Linux console sequences that reconfigure the colour palette, and the title bar control sequences used by DECterm (which are different from the xterm ones; PuTTY supports both).

By default, PuTTY announces its terminal type to the server as xterm. If you have a problem with this, you can reconfigure it to say something else; vt220 might help if you have trouble.
