AT Command Set
I have two documents describing AT Command sets, one is a generic one for modems with Lucent chipsets, the other is for Conexant/Rockwell modems. Both are PDF files that list the AT commands for some modems. AT Commands differ from modem to modem and the ones listed in these documents may not be the ones for your modem. Modem manufacturers often put of PDF copies of their manuals on their websites, check there for information more specific for your modem. I also have a Programmer's Guide (containing AT commands and a lot more) to modems that use a Cirrus Logic chipset.
Newsgroups are public forums somewhat like email, where everyone can see every message. There is a vibrant TAPI community in the newsgroups, and I highly recommend that everyone take a look at what it has to offer. If you have any questions regarding TAPI, please ask them in the newsgroups and do not email people directly. Rest assured, if people know the answer to your question they will indeed help you. More thoughts about email vs. newsgroups can be found in my Email Guidelines.

You will need to use a program like Outlook Express or Mozilla Thunderbird to access newsgroups. Alternately, Google and Microsoft have web portals. If you do not have news server access, Microsoft has a free server for microsoft.* newsgroups at msnews.microsoft.com (the links should take you there). If you need help configuring your news reader, please contact your System Administrator.
