command set.
Product Overview
14
The Appendix features a discussion of standard and
extended ‘AT’ commands and S-Registers as well as
high-level protocols.
Installation Hints
Your modem has been pre-set at the factory for
optimum performance. All defaults are set to allow
the modem to negotiate the best possible connection.
Because of these factory defaults, the suggested
initialization (INIT) string is: ATZ. You should change
the INIT string in all of your software packages to this
INIT string.
If you want to custom configure your stored profiles,
we suggest that you always start out with an
AT&F&C1&D2 before customizing other commands.
This string will reset the modem to the factory
defaults as well as reset some other basic settings. If
modem performance suffers after modifying settings,
send the INIT string above (AT&F...&D2) to the
modem.
Notes on Performance
To get optimum performance from your modem, the
phone line quality over which you are transmitting
and receiving must be reliable and relatively free of
“noise”.
On-Line EXPRESS
15
Operational Requirements
The modem has few requirements and is easy to use.
Be sure to read the information in the Appendix about
connecting to the phone company. In addition, note
the following:
• The communication settings are controlled by the
software that manipulates the serial interface
present in your system. The external modem is
connected to that interface.
• Operating the modem with a computer requires
communication software, either as a stand-alone
product as included here, or as part of an
application program.
• The modem takes a DB-25 (25-pin male connector),
but computer equipment varies. Check the serial
ports at the rear of your system.
• The modem uses an existing serial port on the back
panel of your computer. It can be a 9-pin or 25-pin
D-shell connector. Use the dual end (25-pin or 9-pin)
of the cable supplied with your modem to connect
to your system’s serial port.

No dial tone.
Modem will not
connect to
another modem.
• Verify that you have cables plugged in
correctly as instructed in Section Two.
• Connect a telephone set directly to the
wall jack and check for a dial tone. If
no dial tone is heard, the telephone line
is not working. Contact the telephone
company.
• Check the connections between the
modem and the computer, and the
modem and the telephone line.
• Make sure the telephone jack is
operational as described above.
• The telephone line may be in use at a
different extension.
No response

• Perhaps the number you have called
does not reach a modem, or the remote
modem may not be set up to respond.
• There may be a conflicting port
address. Re-configure the modem’s
COM port address.
SYMPTOM POSSIBLE REMEDY

• Verify that the communication
software is set to the same
communications port where your
modem is attached (e.g., COM1,
COM2). Check IRQ settings in your
software.
• Try typing AT&F to r eset the modem
to its factory defaults.
• Move the modem to another serial
port (power down the host computer
first). If the modem works after
being moved, it’s likely the problem
is not with the modem.

Appendix A: Command/Protocol Overview
In most cases, your communications software will set
and control the operation of your modem. Following
is a brief survey of the most commonly used Hayescompatible AT commands for use with your modem.
In addition, we’ve also provided information on
extended AT command sets, S-Registers, and
commands and registers for high-level protocols such
as V.32/V.32bis.
It will rarely be necessary to use ‘AT’ commands and
S-Registers in command mode. We include them here
for more advanced users who may prefer command
mode operation, or require special settings.
Hayes-compatible commands consist of a basic
command set and an extended command set. The
basic set involves functions such as dialing a number,
or putting the modem on-hook (i.e., replacing the
telephone handset).
Extended commands allow more sophisticated control
of the modem such as transmission speed, or initiating
high-level functions like data compression or error
correction. These functions are defined and controlled
by the available protocols mentioned above. A
protocol is a set of standards by which data
communications operate.
Command/Protocol Reference
22
Every AT command includes an “AT” prefix,
followed immediately by the command and, in many
cases, additional parameters. Multiple commands can
be entered at the same time from the DOS prompt.
AT Command[parameter]AT Command[parameter]
... PRESS ENTER
Example: ATH or ATH0 tells the modem to
disconnect
Extended commands were developed to provide
greater functionality and control over modem
operations. Their format is the same as the basic
command except that an additional parameter is
required following the AT prefix and before the
numerical parameter. This additional parameter
comes in three different forms:
Extended AT Commands:
the ampersand (&) character
the backslash (\) character
the percent ( %) character
Examples: AT&V tells the modem to display (view)
its configuration and user profile, providing the
modem has non-volatile RAM, meaning it can store
limited amounts of information when power is off.
AT%E1 tells the modem to monitor line quality.
On-Line EXPRESS
23
S-Registers
Modem command “language” also employs a set of
indicators or registers, which are various numerical
values all with a standard “S” prefix, hence SRegisters. To a large extent, the values defined in the
S-Registers regulate the operation of the modem and
the function of some commands in the AT command
set.
Example: S-Register 6, or S6=n, defines the length of
time the modem will wait for a dial tone. In this case
the acceptable range is 3-6 (in seconds) with a default
value of 5. With S6=3, the modem will wait three
seconds for a dial tone when going off-hook before
dialing the first digit of its telephone number.
Data Communication Protocols
This can be more than a little confusing. These
protocols represent various domestic and
international standards which enhance modem
performance and reliability. The protocols are
activated and controlled by a variety of extended AT
commands and S-Registers.
The “V-Dot” standards are more numerous, but have
a single origin: the Consulting Committee for
International and Telephone and Telegraph (or
CCITT). Some of the lower-level standards such as
Command/Protocol Reference
24
V.21 and V.22 have “domestic” equivalents as
developed by the former Bell System, also referred to
as Bell standards. The “V.Dot” standards may be
summarized as shown below:
V.21 The CCITT standard for 300bps communications.
Domestic modems follow the Bell 103 standard, but V.21 can
accept international calls at 300bps.
V.22 The CCITT standard for 1200bps communications. The
domestic equivalent is the Bell 212A standard.
V.22bis The CCITT standard for 2400bps.
V.23 CCITT for 1200bps with a 75bps back channel. This is
mostly used in Europe and South America.
V.32 CCITT standard for 9600bps and 4800bps
communications.
V.32bis CCITT standard for an extensive range of high-speed
modems operating at 14,400bps, 12Kbps, 9600bps, 7200bps,
and 4800bps.
V.42 CCITT standard for detection and negotiation for
LAPM (Link Access Procedure for Modems) error control. V.42
will also support MNP levels 2-4.*
V.42bis An extension of V.42 specifying the data compression
protocol for use with V.42.*

S-Registers
This section defines the purpose of the modem registers, and
sequentially lists the registers and describes their functions.
These registers affect various operating characteristics and
allow you to obtain information about the modem, as well as
test the modem. Each register has a factory-set value, which
you can read or change to fit your needs.
Reading a Register Value
To read the current value of a register, type:
AT Sn? [ENTER],
where n is a register number.
AT Sn? Sn? [ENTER] from the command mode.
To read the r egister values of S0 and S1, type
AT S0? S1? [ENTER].
The modem will display the first register value, a carriage
return, the next register value, a carriage return, and OK or 0.
Changing a Register Value
To change a register value, use the Sn command (ATSn=v),
where n is a register number and v is the new value you want
to assign to the register. Type:
AT S0=3 [ENTER]
to have the modem automatically answer on the third ring.
The following table lists the modem’s registers and their
functions.
