Using the Correct Telephone Line Type
Use a standard analog phone line, as in most households. In an
office, use a line connected to a fax machine or modem. Ina hotel,
request a room with a standard phone line or data port. If
necessary, check with the local phone company or administrator
to make sure you’re using the right type of line before sending
data.

AT Commands
TheATCommandSetallowsyoutocustom-configurethemodem.
Only experienced users having difficulty with default settings
should use this.
Changing the Initialization String
Enter AT commands in the Initialization String field of the Modem
Preferences screen.
Basic AT Command Syntax
A command line is made up of three elements:
•Prefix - consists of the characters “AT” or “at” or, to repeat
the execution of the previous command line, “A/” or “a/”.
•Body - made up of individual commands described later.
Space characters (IA5 2/0) are ignored and may be used for
formatting purposes, unless they are embedded in numeric
or string constants. The termination character may not ap-
pear in the body. The modem can accept at least 40 charac-
ters in the body.
•Termination character - may be selected by a user option
(parameter S3). The default is CR.
The format of Basic Syntax commands, except for the D and S
commands, is as follows:
<command>[<number>]
where:
• <command> is either a single character, or the “&” character
followedbyasinglecharacterperV.250;orthe“%”character
followed by a single character, the “*” character followed by
a single character, or the “^” character followed by a single
character.
• <number> is a string of one or more characters from “0”
through “9” representing a decimal integer value. Com-
mands expecting a<number> are noted in the description of

9
Quick Reference
the command. If<number>is missing fromsuch acommand
(<command> is immediately followed by another <com-
mand> or the termination character), the value “0” is as-
sumed. If a command does not expect a <number> and a
number is present, an error occurs. All leading “0”s in <num-
ber> are ignored by the modem.
Additional commands may follow a command (and associated
parameter, if any) on the same command line with a separation
character. The actions of some commands cause the rest of the
command line to be ignored.
S-Parameters
Commands that begin with the letter “S” are known as “S-
parameters”. The number following the “S” indicates the
“parameter number” referenced. If the number is not recognized
as a valid parameter number, an ERROR result code issues.
Immediately following this number, either a “?” or “=” character
must appear. “?” is used to read the current value of the indicated
S-parameter; “=” sets the S-parameter to a new value.
S<parameter_number>?
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 thisinformationtext consistsof
exactly three characters, giving the value of the S-parameter in
decimal, with leading zeroes included.
