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.
