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.
