Command Syntax
For AT command syntax in this chapter, the following
definitions apply:
• Words enclosed in
<angle brackets> identify parameters
that can be specified as part of the command.
• Syntactical elements enclosed in
[square brackets] are
optional and may be omitted from the command line.
• Syntactical elements enclosed in
{brackets} are required
and must be specified as part of the command.
• The use of
| between syntactical elements indicates that
only one of the elements may be specified as part of the
command. For example, the command syntax for
S3{=<value>|?} must be either S3=<value> or S3?.
•The
+ and $ characters are used to identify extended AT
commands.
+ and $ denote standard and
manufacturer-specific extended commands respectively.
•A semicolon (
;) is used to concatenate additional
commands (basic or extended) after an extended
command.
Basic AT Commands
This section defines the basic AT commands that the
GSP-1620 modem currently supports and the functionality
provided by each. For all basic AT commands that require a
<value> parameter, if <value> is not present then a 0 is
assumed by the receiver.
The basic AT commands described in this section return one
of two possible result codes, which are listed in Table 6-3. Any
commands with exceptions to this have separate result code
tables in their sections.
