Chapter 4—MODEM AT Commands, S-Registers, Result Codes

Modem S-Registers

This chapter describes the ISIHI-2S’s S-registers, which are small regions of memory where modem configuration information is stored. Whereas AT commands tell a modem what to do, S-registers tell the modem how to do it. Each S-register has a name that consists of the letter S and a number (S0, S1, S2, etc.), hence the term S-register. Use the Sr? command to read the value stored in an S-register and the Sr=n command to change it.

Modem

S-Registers

S0 Number of Rings Until Modem Answers

Unit: 1 ring

Range: 0–255

Default: 0

S0 defines the number of rings the modem waits before answering an incoming call. The default value is zero (0), which effectively disables the auto-answer function. When auto- answer is disabled, the modem can only answer via the ATA command. Set the S0 register value to one (1) to causes the modem to answer the call immediately after the first ring. The maximum number of rings that can be configured is 255.

S1 Ring Count

Unit: 1 ring

Range: 0–255

Default: 0

S1 counts the number of rings that have occurred. It is a read type of register and is seldom 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 the value reverts back to zero.

S2 Escape Code Character

Unit: Decimal

Range: 0–255

Default: 43 (+)

S2 defines the escape code character by its decimal ASCII code. The default character is the plus (+) sign (decimal 43). S2 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 online mode without breaking the online connection, unless you use the BREAK method.

Note: If you change the S2 value, you must make corresponding changes in your data communications software.
