S registers
S registers are information storage areas inside the modem. The AT command set uses the S registers to
congure modem options. Some S registers have default settings. These are usually adequate for normal
modem operations. In special circumstances, however, you may need to change some defaults.
To read or change the value of an S register, begin the command with the letters AT.
To read the value of an S register, use the command AA
A
TT
T
Sr?Sr?
Sr?
where r is a register number 0-110. For example,
to read the value of S register 0, type ATS0? and press Enter.
To change the value of an S register, use the command AA
A
TT
T
Sr=nSr=n
Sr=n
where r is a register number 0-110, and
n is the new value you want to assign. For example, to change the value of S0 register to 20 rings, type
ATS0=20 and press Enter.
Refer to the following table of S registers:
