Introduction

This chapter covers MT2834MR software registers called S-Registers, where certain MT2834MR 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). Refer to Section 4.2, Reading and Assigning S-Register Values.
S0
Number of Rings until Modem Answers
Unit: 1 ring
Range: 0-255
Default: 1
Description: S0 defines the number of rings the modem waits before answering an incoming call. The
default value is one ring (Decimal 1), which means that the modem answers the call
immediately after the first ring. The maximum number of rings that can be configured is
255. Setting the value to zero (0) disables auto-answer completely.
S1
Rings which have Occurred
Unit: 1 ring
Range: 0-255
Default: 0
Description: S1 counts the number of rings that have occurred. It is a "read" type of register and is
seldom, if ever, used in typical operation. Each time an incoming ring signal is detected, S1
increases its value by one, up to a maximum of 255. If you set S1 to a value other than its
default value of zero, or if the value is increasing with rings, this new value remains stored
in S1 for eight seconds after the last ring is counted, after which time the value reverts back
to zero.
S2
Escape Code Character
Unit: ASCII
Range: 0-127
Default: 43 (+ sign)
Description: S2 defines the escape code character. The default character is the plus (+) sign (Decimal
43). It may be set for any ASCII character. Setting an S2 value greater than 127 results in
no escape character, and therefore no means of entering Command mode from On-line
mode without breaking the on-line connection.
S3
Return Character
Unit: ASCII
Range: 0-127
Default: 13
Description: S3 defines the character recognized as Carriage Return (ENTER) or Return. The default
setting is CTRL-M (Decimal 13), which is the ASCII code for the ENTER key on most
keyboards. S3 may be set for any ASCII character.
