Command Reference

Test syntax: +<name>=?
The modem responds to this command with a list of the supported parameter
ranges.
S Register Conventions
S registers contain parameters used by the modem. The presentation format for
an S register is similar to the format used for an AT command. Each S register has
a standard layout consisting of the following:
S register title.
S register description.
Parameter description.
The S register title is formatted in large bold letters and begins with a capital S
followed by the register number. The title also includes a descriptive name for the
register. The S register description defines the parameter the S register
represents.
S register parameters can have a variety of effects on the functionality of the
modem. As a result, the parameter description can have several forms. The most
common form includes the parameter range, the parameter default, and the units
used by the parameter.
Sample S2—Escape Character (User-Defined)
S2 contains the decimal value of the ASCII character used as the escape
character. The default value corresponds to an ASCII +. The escape sequence
allows the modem to exit data mode and enter command mode when on-line. A
value over 127 disables the escape process, i.e., no escape character will be
recognized.
Range: 0—255.
Default: 43 (+).
Units: ASCII.
