Subject: Break key

I in the past have used the rather crude method of switching to a slower
line speed and sending a few characters then switching back to the
original line speed.  This worked with GTE Telenet, but I don't know
about other systems.  I know this is rather crude, but being rather
crude is better than suffering through many lines (or pages) of unwanted
information.  The only other solution that I know of is using some
hardware-specific feature of the particular computer that you happen to
be using.  There is no implementation of a break key in regular CP/M.
