OK, AT&FZ then. The difficulty with ATZ is that there are numerous
settings that are restored on ATZ that may be locally configured into
extremely odd and wacky patterns that get restored on the next
ATZ. Not good, and not reliable.

I can see XONXOFF: this makes sense, and the config.* structure is
now set up in a much more legible way to let the users modify this.

This man page is incorrect. Read the hylafax/config/skel file in the
CVS sources.  The default is actually rtscts. Man pages are great:
source is better. And this one may be my fault: I re-arranged the
skel/class[1,2,2.0] files into a much more orderly setup some time back,
and may have missed this man page correction.
