Section Two: Product Overview

The On-Line

EXPRESS modem by

Boca Research, Inc.

combines highspeed data, modem, and fax capability on

14.4

a single device. It also features V.32bis, which provides high-speed data transmission.

Features

• Data transmission rates of 14.4K, 12K, 9600, 7200,

4800, 2400, 1200, or 300bps.

• Programmable speaker volume control

• Auto-speed sensing.

• Data throughput up to 57,600bps (with RPI support).

• Group 3 send and receive fax capability with support for Class 1 and Class 2 fax commands.

• Full error control (V.42 LAPM, MNP2-4) and data compression is available through host communications software that supports RPI. See

Appendix E for a list of software developers who support this protocol.

• 100% data compatibility with the Hayes ‘AT’ command set.

Product Overview

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

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.

Product Overview

Section Three: Troubleshooting

This section lists common problems that may be encountered and their possible solutions.

SYMPTOM

No dial tone.

POSSIBLE REMEDY

• 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.

Modem will not connect to another modem.

• 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.

• Perhaps the number you have called does not reach a modem, or the remote modem may not be set up to respond.

No response when you type in

AT commands

• There may be a conflicting port address. Re-configure the modem’s

COM port address.

On-Line EXPRESS

SYMPTOM

No response when you type in AT commands (contd)

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 reset 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.

AT commands not visible.

• Make sure the echo command is set to ON. Change to echo with the ATE command.

After data connection is established, data is displayed as garbled characters.

• Make sure the local (yours) and remote modem configurations are compatible.

• Verify that both modems are operating with the same settings, speed, data, parity, and stop bits.

• The software may not be set for correct terminal emulation.

Configure software to correct type.

ANSI terminal emulation is most commonly used.

Troubleshooting

SYMPTOM POSSIBLE REMEDY

After data connection is established, data is displayed as garbled characters.

(contd)

• Power down your system and re-run your communications software. Check software settings.

• Exit the communications program and restart it.

The modem does not answer an incoming call.

• You may not have enabled auto-answer.

Use your software to enable this function.

• If you have an answering machine, it may be answering before the modem can. Turn the answering machine off, or, use the software to set auto-answer to respond in fewer rings than the answering machine.

Modem disconnects while on-line.

• Check for any loose connections.

• Re-try the connection by dialing the number several times. You may be experiencing line interference.

• An incoming call may have broken the connection if a call-waiting feature was enabled. Disable call-waiting and try again.

My software does not support a speed of

14.4Kbps.

• 14.4Kbps refers to modem to modem speed. Select 19.2Kbps (or faster if your hardware supports it) for computer to modem speed.

On-Line EXPRESS

SYMPTOM POSSIBLE REMEDY

I am having trouble getting my init string to work.

• Init strings are primarily personal preferences. Use the most basic one that can get the job done. See Installation

Hints, page 8.

My 2400bps (or other modem) worked with my system but the this modem does not.

• Review earlier suggestions.

• Make sure you use software included with modem.

I need the modem to connect at a certain speed.

Connection

Errors.

• Send an AT&Q6N0S37=n where n= 9 for

9600, 6 for 2400, 5 for 1200, 1 for 300bps.

• Try connecting at a lower speed (e.g.,

9600 or 2400bps).

• Turn off error correction/compression with an AT&Q6%C0 command.

• Noisy/poor line conditions may prohibit connection. Have your phone company test your lines.

• Verify that the modem at the other end is up to date and compliant with current

CCITT and Bell standards.

Troubleshooting

SYMPTOM

Problem

Connecting to

On-line subscription services.

POSSIBLE REMEDY

• Some on-line services require that your modem be configured to run with error correction and data compression turned

OFF

. The easiest way to accomplish this is by using the command

AT&Q6

and setting the communication software to the correct baud rate for the service you are calling (e.g., 2400, 9600bps). If you still have problems connecting, try forcing the modem to connect up at the slower speed with the commands

AT&Q6F5 for 2400 baud, and AT&Q6F8 for 9600 baud services.

On-Line EXPRESS

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

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

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 S-

Registers. 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

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.*

Report Received Signal Level.

AT%L 009 = -9 dBm, 010 = -10dBm, etc. all the way to

043 (-43 dBm)

Line signal and noise are determined by the unit of measurement dBm (decibel referenced to one milliwatt). To arrive at a signal/noise ratio, the noise level is subtracted from signal level in dBm.

Report Line Signal Quality. Returns a “high-order” byte of the calculated EQM (“eye quality monitor”). This can range from

0 to 255. When the value is 8 or greater, the modem will automatically retrain if enabled by the AT%E1 command. The value for a normal connection ranges from 0 to 2 and approaches 8 for a progressively poorer connection. Returns an OK result code.

000 to 007 no retrain

008 to 255 retrain performed if enabled by %E1.

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 register 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.
