Having recently downloaded Zterm version 0.8, I thought I'd take it
out for a spin, so I logged onto my local UNIX(TM) machine, and tried
to do some of the standard things.   Started out smooth, but as soon
as I tried to edit a file, I ran into trouble...  I use emacs, which
we all know uses lots of control characters to do interesting things.
I seem unable to cause Zterm to pass the control characters through.

Where have I gone wrong? (Even if you claim it's in using Emacs, I'd
like to be able to send control characters!)

I assume there's some option hidden away somewhere.  I  selected the
VT100 terminal and standard macintosh & Dec keyboard option.  Was 
that a mistake?  I tried using both Option and Command as the control
key.  I thought the docs said the author used the option key as a cntl
key.  I also tried both with and without the keymapping on (or at least
changed the option while running).  

I have a MacPlus with the standard keyboard, and a Radius Accelerator
board (which I suspect has nothing to do with it).  I'm running under
multifinder using system 6.0.2.

Thanks for any suggestions.
