S<parameter_number>=[<value>]

If the “=” is used, the new value to be stored in the S-parameter is specified in decimal following the 
“=”. If no value is given (i.e., the end of the command line occurs or the next command follows 
immediately), the S-parameter specified may be set to 0, or an ERROR result code issues and the 
stored value remains. The ranges of acceptable values are given in the description of each S-
parameter. 

If the “?” is used, the modem transmits a single line of information text to the DTE. The text portion 
of this information text consists of exactly three characters, giving the value of the S-parameter in 
decimal, with leading zeroes included.

The tables that follow summarize the AT commands, result codes, and S-Registers for the MDM 3000. 
<string> represents a letter, number, or symbol to be entered. <value> represents a number to be 
entered. Possible values are listed below the command.
