4-4 CHAPTER 4: DIALING, ANSWERING, AND HANGING UP
Answering Calls Your modem can be configured to answer calls. By default, your Business
Modem will not automatically answers calls.
Force Answer Mode
Auto Answer You can set your modem to Auto Answer using the ATS0 command
.
Example: Sending ATS0=0 will not allow your modem to receive calls
when you are not present.
See the S-Register summary in Appendix A, S-Registers for more
information about instructing the modem to answer after more than 1
ring.
When your modem senses a call coming in, it sends the result code RING
to your computer, goes off hook, and negotiates for a connection. If
there is no response within 60 seconds, the Business Modem hangs up.
For more information about adjusting the 60-second wait-for-connection
time using S-Register 7, see Appendix A, S-Registers.
When a call is disconnected, the Business Modem hangs up and returns
the NO CARRIER result code.
If S0=0, Auto Answer is disabled. To determine if Auto Answer is NOT
disabled send the command ATI4 and be sure that S0=1-255.
