Making a Call

The following examples show how to place a call using several of the dial modifiers.

ATD 1234567

The modem dials the telephone number 1234567 and then waits for a carrier from a distant, or remote modem. If no carrier is detected within a given time (as defined by the initial settings in S-Register 6), then the modem automatically releases the line and sends a NO CARRIER result code. If a carrier is detected, the modem gives a CONNECT result code and goes on-line, allowing communications with the remote modem. The connection between the two modems ends when any of the following occurs causing the modem to hang up, return to command mode, and send the NO CARRIER response:

• The local modem loses the carrier signal from the remote modem.
• The Hang Up command (H) is sent.
• The DTR interface signal is dropped between the local DTE and modem when the &D2 or &D3 command is in effect.

AT &F1DT9,P5551234 [Enter]

This command restores the factory default settings, dials, using tones, a 9 to access an outside line, pauses briefly, then pulse dials the number 555-1234.
