Answering a call

Your ISDN modem can answer a call automatically, or you can manually instruct the modem to answer the line when it rings.

Manual answering. When an incoming call is detected, the RING result code will appear on the computer screen. By typing ATA and pressing the Return key, you instruct the modem to answer an incoming call manually. Your modem then attempts to connect to the remote modem. If the two modems are compatible, your modem receives a carrier signal from the remote modem, and a CONNECT response appears on the screen.

Automatic answering. You may use the modem to answer incoming calls automatically. Enable auto-answer by setting S register O to 1 (ATS0=1). Your ISDN modem can answer incoming calls unattended if you have the proper communications software, such as bulletin board software or an electronic mail system.

Disabling auto-answer.You can disable auto-answer by setting the value of S register O to the default 0 (ATS0=0). When the modem first receives power, is reset, or the factory settings are recalled, the S registers return to the stored settings. When SO=0, your modem sends the RING result code to your computer screen when an incoming call is detected, but it does not answer the call automatically.
