256 Colours with Vim and PuTTY

This is more for my own edification, and is really a collation of other stuff I found:

Step 1: Configuring PuTTY

When creating your session, under Window -> Colours, check the top 3 box es:

• Allow terminal to specify ANSI colours
• Allow terminal to use xterm 256-colour mode
• Bolded text is a different colour

Under Connection -> Data, make sure Terminal-type string is xterm-256color, or xterm

Step 2: Configuring Vim

In your .vimrc add the following:

if &term =~ "xterm"
 set t_Co=256
 if has("terminfo")
   let &t_Sf=nr2char(27).'[3%p1%dm'
   let &t_Sb=nr2char(27).'[4%p1%dm'
 else
   let &t_Sf=nr2char(27).'[3%dm'
   let &t_Sb=nr2char(27).'[4%dm'
 endif
endif
