See the S-Register summary in Appendix A, S-Registersfor 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.
