Hardware

Click “OK” when finished. After you have done this, save your new connection by
selecting “Save” from the “File” menu and click “OK.” A new connection icon will be
added to your Hyper Terminal folder.

You are now ready to start entering AT commands.

In the terminal window, type:

AT<Enter>

Comet responds

OK

This confirms that the modem and your computer are communicating correctly.

To test the telephone line connection issue the manual answer command.

Type:

ATA<Enter>

The Comet will pick up the phone line, and try to communicate. Normally, this
command is only used to answer an incoming call made from another modem. Thus the
high pitched noise you will hear from the speaker. To abort the operation, press any key,
or select “Disconnect” from the “Call” menu.

Dialing and Answering Techniques

Depending on what communications software you use to make modem connections,
you may not have as much control of how the modem dials the telephone number. This
section shows some useful examples of the AT commands used for dialing and
answering operations. The command characters specific to each function are shown in
bold type.
