Ray, There is a good list of AT commands at http://docs.kde.org/stable/en/kdenetwork/kppp/appendix-hayes-commands.html The ATI9 will return the Apple product code and firmware version of the modem. Check out http://www.tidbits.com/iskm/modems.html#aa7 for the Apple/Hayes AT commands. -Darin Date: Sat, 19 Aug 2006 13:15:16 -0400 From: Ray Arachelian <ray at arachelian.com> Subject: Anyone have an Apple Modem 1200 or 300 manual? To: cctech at classiccmp.org Message-ID: <44E74724.2040706 at arachelian.com> Content-Type: text/plain; charset=ISO-8859-1 I'm wondering if this was a Hayes compatible modem, and if so what the result strings were for various commands such as just "AT" by itself, and "ATI", "ATI0" and so on.
