	Actually, I don't believe any document lists any default values;
they're all meant to be negoiated.  The unofficial-official setup for
the last 10 years however, has been to try to manage char mode,
including echo off.  The previous 10 years before that were attempting
either line mode, or a variant known as line-mode kludge, with echo on.

	Most existing MUDs today hearken back to a day ..well.. more
than 10 years ago.  They almost uniformly assume line-mode kludge, with
echo on by default where applicable.  

	Mileage may vary.

	Other items such as the value of a delete character are
increasingly tricky with linemode.   Most MUDs assume, and leave it at
that.  I don't know the correct way to handle this offhandedly in line
mode.  With character mode, it's fairly simple to handle; you can simply
say 'delete is \008 or \127' (backspace and delete, respectively, unless
I messed that up) and it will be your server managing each item, and
you'll be echoing it back to the user.

	It's also necessary if you want to - for example - do something
with those arrow keys, like shell-style command history, or heaven
forbid, moving.  Still, a MUD with command/name completion would be
quite neat.

	You corrected me before I corrected myself, it appears.  Good
tools are the most important for high productivity.  The capabilities a
scripting system are second compared to the user's ability to access
