Example: Writing to an S-Register

If you wish to have your modem automatically answer incoming
calls, you would change the value in the S0 register. This register
determines whether your modem is in auto-answer mode or not,
and is by default 0 (auto-answer is disabled). Setting the register
to any other value will cause your modem to answer incoming
calls after the specified number of telephone rings. So, for
instance, if you want your modem to answer incoming calls after
two rings, you would type ATS0=2 <Enter>.

Bit-Mapped Options S-Registers

Several S-registers are referred to in this guide as Bit-Mapped
Options. This indicates that the S-register provides information
on several modem options. To determine the value for a particu-
lar Bit-Mapped Option S-register, you need to add together the
values associated with each of the appropriate options. The
values for all the options described by a particular Bit-Mapped
Option S-register are given in tables under the S-register descrip-
tion. The following example shows you how to determine the
appropriate value to write to an S-register in order to set more
than one option.
