Issuing the On Hook command while the call is still ringing disconnects the incoming call. The DAC disconnects the call and notifies you with a NO CARRIER message.

When the S0 register is set to 0, the DAC is set to manual answer, and an inbound call must be answered with the Answer command. You can also abandon the call with the On Hook message, as in the Autodial sequence.

Off Line mode

Off Line mode acts as a sort of Hold mode. Once the call is answered and the session begins, the Off Line command enables you to enter Hayes command modes. The Off Line sequence is transmitted to the far-end, but at the end of the sequence, the command mode is initiated. At this point, any Hayes command except Dial Number can be executed. Once the desired command is completed, you can return to the call through the On Line command.

The Guard Time (S12 register) defines the amount of time for no local input for the Off Line escape sequence to take place. If the S12 register is set to 0, enter the escape character defined in the S2 register. For a complete list of the parameters allowed for each S Register, see Table 157 on page 481 describing the S Registers.
