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".
