This contradicts what I have read in the popular press.  My
understanding is that Bizcomp claims to have invented the idea of
having a guard time before and after the +++ escape sequence.  The
presence of the guard time allows the escape sequence to be in-band
without being triggered by data.  Hayes has some kind of agreement with
Bizcomp to use this.  I doubt that anybody actually owns the AT command
set itself.
