After looking at the patch and some commentary that I got from the
author, it appears that in raw mode this feature is disabled, so emacs
should work OK.  It also prints the information on SysReq (or
something like that).  Keep in mind that there is no ASCII character
that corresponds to many of the keys on they keyboard, so it has to be
something that both local and remote users can type.  It also has to
be something that will work inside of X windows.  ^T seems reasonable
enough to me, but I'd like to see that under user control somehow.

This is also how it worked on TOPS-20, VMS, and RSTS/E.
