Und das Reset mit AT&D3. Steht glaub' ich nicht im Handbuch.

Da einiges nicht im Handbuch steht, habe ich mir mal die Freiheit genommen,
nachfolgend (aus comp.dcom.modems uebernommen) den Kommandosatz des
Zyxel 4.12  ROMs anzuhaengen.

   My thanks to Michael Schuster for posting the initial version of this
command summary for version 4.12 of the ZyXEL software.  The text that
arrived at my site badly needed some formatting fixes, so I made them, fixed
some spelling errors, and fixed what appeared to be some errors.  The Class 2
FAX command summary section looked like some of the command names were
missing (though the descriptions were still present), so I restored them as
best I could, too.  Any notes I added are marked with my initials.
