S-Register List
S-Registers affect the operating parameters of the 391x Series modems. S-Registers are only
applicable when the DTE Dialer Type configuration option is set for AT. (Refer to the &Mn and
&Qn commands.)
Table 14-3 lists all S-Registers supported by the 391x Series modems. The first column lists the
S-Register. The second column lists all possible values for that register. The third column lists the
key sequence used to enter the equivalent from the DCP. Use this column to reference commands
in Chapter 5, DCP Configuration, if further description is necessary.
NOTE
In some countries, the range of allowable values of some
S-Registers are restricted. If the DTE attempts to enter an illegal
value, the modem will answer OK, but it will set the register to the
closest legal value. The DTE can check the actual value of the
register with Sn? command.
