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 336 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 336 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.
