S Register Conventions

Sample S2—Escape Character (User-Defined)

Other Document Conventions

Test syntax: +<name>=?
The modem responds to this command with a list of the supported parameter
ranges.
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.
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.
For the sake of clarity, the following conventions have been adopted and used
throughout this document.
