Unlike RTTY and other data modes, Morse does not differentiate between 
capital and small letters, Leo.  I suppose the obvious way to emphasise 
something would be to repeat each word twice.

Anyone know what the Morse sequence is for the @ character?  There ought 
to be one so we can send e-mail addresses these days.  And please don't 
say 'use "at"'.  The word "at" is not international ;-)
