Command Token Types
Basic Syntax Command Format
The format of Basic Syntax commands (except for the D and S commands) is:
<command>[<number>]
where:
<command> is either a single character, or the "&" character (IA5 2/6) followed by a single
character.
Characters used in <command> are taken from the set of alphabetic characters.
<number> may be a string of one or more characters from "0" through "9" representing a
decimal integer value.
S-parameters
Commands that begin with the letter S constitute a special group of parameters known as
"S-parameters". These differ from other commands in important respects:
• The number following the S indicates the "parameter number" being referenced. If the
number is not recognized as a valid parameter number, an ERROR result code is issued.
• Immediately following this number, either a "?" or "=" character (IA5 3/15 or 3/13,
respectively) appears:
"?" is used to read the current value of the indicated S-parameter.
"=" is used to set the S-parameter to a new value. "<parameter_number>"
"<parameter_number" =[<value>]
If the "=" is used, the new value to be stored in the S-parameter is specified in decimal form
following the "=".
Extended Syntax Command Format
Both actions and parameters have names, which are used in the related commands. Names always
begin with the character "+" (IA5 2/11). Following the "+", from one to sixteen (16) additional
characters appear in the command name.
All (GSM) cellular commands have the prefix "+C".
All Fax commands have the prefix "+F".
All General modem commands have the prefix "+G".
Most Motorola propriety commands have the prefix "+M".
