is not recognized, one or more mandatory values are omitted, or one or more values are of the
wrong type or outside the permitted range, the modem issues the ERROR result code and
terminates processing of the command line. An ERROR is also generated if too many values
are specified. In case of an error, all previous values of the parameter are unaffected.
Parameter Read Command Syntax
The DTE may determine the current value or values stored in a parameter by using the
following syntax:
+<name>?
The modem responds by sending the current values stored for the parameter to the DTE in an
information text response. The format of this response is described in the definition of the
parameter. Generally, the values are sent in the same form in which they would be issued by
the DTE in a parameter setting command; if multiple values are supported, they will generally
be separated by commas, as in a parameter setting command.
Parameter Test Command Syntax
The DTE may test if a parameter is implemented in the modem, and determine the supported
values, by using the syntax:
+<name>=?
If the modem does not recognize the indicated name, it returns an ERROR result code and
terminates processing of the command line. If the modem does recognize the parameter name,
it returns an information text response to the DTE, followed by an OK result code. The
information text response indicates the values supported by the modem for each such
subparameter, and possibly additional information. The format of this information text is
defined for each parameter.
2.4.5 Additional Syntax Rules
Concatenating Commands after Extended Syntax Commands
Additional commands may follow an extended-syntax command on the same command line if
a semicolon (";") is inserted after the preceding extended command as a separator. The
semicolon is not necessary when the extended syntax command is the last command on the
command line.
Concatenating Commands after Basic Format Commands
Extended syntax commands may appear on the same command line after a basic syntax
command without a separator, in the same manner as concatenation of basic syntax
commands.
