   I think you must be right, I just checked a current Hayes manual and
compared it with an old one from that place I used to work.  The old
one just says that you can specify X0 or X1 for regular or extended
result code sets (CONNECT 1200 in addition to CONNECT) but nothing about
detecting remote rings, busies, or whatever.  The newer manual has the
info as you describe.  I tried these on the old modems and they definitely
don't work.  So, in summary, anybody using a Hayes modem: if you bought
it about 2 years (or more) ago then it may not have these capabilities.
