	by AT command or by entering the new value of the S Register, preceded by AT.

	For example, to change from manual answer to auto-answer after three rings,
	follow these steps:

1Check the S Register table for the register that controls Answering. The functions are listed in alphabetical order.

2Start your communications software and enter Terminal mode.

3Type ATS0=3 and press [Enter]. The modem will now answer a call after three rings.

All values are in decimal format. Default values indicated in bold type are those written after execution of the &F0 command.

For storable register, however, the value after reset will be set to that stored in the appropriate stored profile.
