Chapter 6 - S-Registers

6.1Introduction

Certain Command Mode configurations are stored in memory registers called, S-Registers. The S command is used to assign a value to, and to read the current value of an S-Register. To assign a value to an S-Register, enter the letter S, followed by the S-Register number and an equals sign (=), and then a decimal response to the message “ENTER THE NEW VALUE IN DECIMAL FORMAT”. To read an S-Register value, enter the letter S followed by the S-Register number and a question mark (?), then hit RETURN. To verify that the S-Register value was entered correctly, enter for example, ATS8? and hit RETURN. You should receive a response of the assigned value given to that S-Register.

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 to zero.

S2

Escape Code Character

Unit:

ASCII Character

Range:

0-127

Default:

43 (+)

Description:

S2 defines the escape code character. The default character is the plus (+) sign

 

(Decimal 43), but 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 Character

Range:

0-127

Default:

13 (^M)

Description:

S3 defines the character recognized as Carriage Return (RETURN) or “Enter”. S3

 

may be set for any ASCII character.
