Hello.
How can I use modem AT commands in Compact Framework?
And is it poseble on PPC Emulator (I use Compact Framework SDK 2003 and
VS.NET 2003)?
 
AT commands are simply text out the serial port on which the modem is
connected. Look at any serial library, such as the one from OpenNETCF.org
or Dick Grier.

Is there any newsgroup fro AT commands?

While there are some standard commands the exact ones supported by a
particular device can vary depending on the chipset etc used. Often modems
will have an accompanying guide of supported AT commands. There is a starter
for 10 here:-
http://support.microsoft.com/?kbid=164660

I'm not aware of a specific newsgroup but you should be able to find more
references like this using google.

Hi,

The point is that you need to use a serial interface class, such as CFSerial
from my homepage, or Serial from www.opennetcf.org. Then, you open the port
and send whatever commands are needed for your specific serial device
(usually a modem).

What sort of information do you need about the commands, or other issues?

AT commands and Web pages have *nothing* to do with each other. They are at
totally different levels of the communication tree. You are not going to be
using AT commands, if you need to establish a connection which will support
full TCP/IP communications. You need to look at the Connection Manager,
etc. and forget all about AT commands...

Hi,

No. That's why I asked. What you want has nothing to do with AT commands,
per se. Dialing your modem and connecting uses RAS services or the
Communications Manager API, not Windows serial communications APIs. You
might use google to locate some information (for example, the first two are:
http://www.developer.com/ws/pc/article.php/3361271 and
http://devbuzz.com/content/init_listings.asp)
