Appendix G
MMH2834 S-Registers
Introduction
This section covers the MMH2834 memory (option) registers called S-
Registers, where certain MMH2834 modem and command mode
configurations are stored. Each S-Register is assigned a number (S0,
S1, S2, etc.). Use the S command to read and/or change the value
stored in an S-Register (ATSr? to read and ATSr= to change S-Register
values).
S0
Number of Rings Until Modem Answers
Unit: 1 ring
Range: 0-255
Default: 1

before answering an incoming call. The default value is one ring

is 255. Setting the value to zero (0) disables auto-answer completely.
