Notes:
1. See Vn for result code selection, i.e., short form (result code) or verbose/extended (result message).
2. See Wn for extended connect message control.
3. See S95 for extended result code enabling options (which override some Wn commands).
4. See Xn for extended result code subset enabling options.
5. See +MR for modulation reporting control.
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

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.
