Mu uses Comint Mode to do its job. This has the added benefit of providing you with an entire communication infrastructure. Minibuffer history, moving between prompts, highlighting of SGR (escape sequences controlling colors on a tty) using Ansi Color, etc.
Use ‘mu-open’ to open a new connection. This will create two buffers for you. One buffer is the mu connection buffer. All the output from the host appears here. You can also type your commands here, but this will get confusing rather quickly as output gets added while your type.
That’s when the other buffer, the mu input buffer, comes into play. Whatever you type there will get sent to the mu connection buffer as well. If you do that, input and output will happen in two different buffers.
The only important buffer is the mu connection buffer. The mu input buffer is just for convenience. You can create more mu input buffers using ‘mu-input-buffer’, or you can kill all mu input buffers. It doesn’t matter.
Before you can open new connections, you must customize ‘mu-worlds’. As soon as you have done that, use ‘mu-open’ to play.
Use Ansi Color. Here’s how to install it in your ~/.emacs:
(autoload 'mu-open "mu" "Play on MUSHes and MUDs" t) (add-hook 'mu-connection-mode-hook 'ansi-color-for-comint-mode-on)
Switch to the output buffer and use ‘M-x mu-dos’ if your host is sending you DOS line endings (ie. you have a ^M at the end of every line). ‘set-process-coding-system’ can be used to set output and input coding systems. There is probably some smart way of adding this to ‘mu-connection-mode-hook’.
(defun mu-dos () "Set coding system of the current buffer's process to DOS." (interactive) (set-process-coding-system (get-buffer-process (current-buffer)) 'iso-latin-1-dos 'iso-latin-1-unix))
