2Introduction

Motorola's SM56 Modem is a feature-rich modem at an attractive price. It provides high-speed

communications between your personal computer and a remote location, such as an Internet

Service Provider (ISP), so you can:

•Receive data at up to 56 Kbps in V.90 or K56flex modes

•Get automatic fallback to V.34 (33.6 Kbps) rates in bad line conditions and on non-

V.90/K56flex headends

•Use your computer as a telephone answering machine (TAM)

•Send and receive faxes on your personal computer at rates up to 14.4 Kbps

•Use your computer as a video phone to place and receive video phone calls

(Data/Fax/TAM/Speakerphone modem with video equipment)

•Use your computer to conduct hands-off speakerphone voice calls

(Data/Fax/TAM/Speakerphone modem)

Important

The SM56 ISA modem runs on Windows 95, Windows 98, and it can be used by applications that

run in an MS-DOS box (under Windows 95/98). Windows 95 and Windows 98 use the same

SM56 software builds.

The SM56 PCI modem also runs on Windows 95 and Windows 98. It does not directly support

Windows 95/98 DOS box applications. Refer to the Troubleshooting section for information on a

third party COM port virtualizing/trapping application that allows the SM56 PCI modem to be

used with DOS box applications.

Personal-computer OEMs that incorporate the SM56 can benefit from sizable cost reductions,

hardware reduction, and lower power consumption. End users benefit from quick, easy and

affordable software upgrades, which help them keep current with the latest communications

technology.

Please check with your direct modem supplier for the latest software updates and other product

information.

3Personal Computer Requirements

Motorola performs rigorous, exhaustive testing on its modems. It developed a list of recommended

personal computer features that perform well with the SM56. The information includes qualified

CPUs, Level 2 cache requirements, operating systems, RAM requirements, and third-party sound

card compatibility. However, in today's dynamic technology markets, it is not possible to test all

components and combinations on all systems.

This section outlines minimum system requirements for SM56 operation. On these systems, CPU

loading was found to be acceptable and the modem demonstrated good performance over the entire

network model.

Important: SM56 operation is not limited to the personal computer systems listed here.

Recommended CPUs

The SM56 modem has been qualified (tested for processor loading and TSB network model

coverage) on the following processors:

•Intel Pentium, 150MHz with MMX, 256K Level 2 (L2) cache

•Intel Pentium, 200MHz, 256K L2 cache

•Intel Pentium II

•Intel Pentium Pro

•Intel Celeron (Pentium II, 266MHz, no L2 cache)

The SM56 functions satisfactorily on the following systems. However, it has not been fully

qualified (it was not tested for processor loading or TSB performance):

•AMD K6, 233 MHz, 256K L2 cache

•AMD K6-2, 256K L2 cache

•Cyrix 6x86MX, 266MHz, 256K L2 cache

The SM56 does not function on the following CPUs, whose floating-point performance is

insufficient:

•Cyrix MediaGX

•Cyrix MediaGXM

•Cyrix 6x86

Level 2 Cache Benefits

Level 2 (L2) cache is an instruction memory (SRAM) bank that resides outside the CPU core. It

holds many instructions close to the CPU, to reduce the need for the processor to use slow access

cycles fetching instructions from main memory (DRAM). Eliminating most CPU accesses to main

memory considerably improves overall system performance.

The SM56 Software Modem works best when a minimum of 256K L2 Cache is installed on the

computer system motherboard to minimize processor loading. Intel's Celeron (266MHz PII)

systems do not have L2 cache. Although the SM56 operates on those systems, host processor

loading increases in the absence of L2 cache.

Compatible Operating Systems

The SM56 modem will run on the following operating systems:

•Windows 95 (OEM Service Release 2.0 or later)

•Windows 98

•DOS Box under Windows 95/98. Note that the SM56 PCI modem does not include direct DOS

box support. Refer to the Troubleshooting section for information on working around this

limitation.

System RAM Requirements

The SM56 Modem operates on systems that have the minimum RAM required by the installed

operating system. As with L2 cache, the more main memory, the better. The recommended RAM is

twice the required minimum. This reduces slow hard-disk swapping and improves overall system

performance... especially when executing numerous concurrent processes. The minimum RAM

requirements are:

Windows 95/98 16 MB

4Preparing the Computer for SM56 Installation

To ensure problem-free installation of the SM56 modem, ensure that an IRQ is available, as

follows.

1. In Win95/98, open the Control Panel.

2. Double click the System icon.

3. Select the Device Manager tab.

4. Highlight the Computer icon.

5. Select the Properties radio button.

6. Ensure that the Interrupt Request (IRQ) radio button is selected.

This displays the IRQ lines that are in use on the computer. Available lines are not shown in the

list. To install the SM56 ISA modem hardware, interrupt line 3, 4, 5, 6, 7, or 9 must be available.

The PCI SM56 software modem can use an IRQ in the range 3 through 15.

If there is no IRQ line available for the SM56 disable one of the COM ports in the BIOS.

Note: If you are using a Windows 95/98 DOS box application, the modem requires two IRQs.

Refer to the Troubleshooting section in this document, or to the on-line User's Guide for more

information on DOS application support. You can access the User's Guide through the modem

Control Panel.

Important: The SM56 PCI modem does not directly support DOS box applications. Please refer to

the Troubleshooting section for information on how to get around this limitation.

To ensure that COM Port 2, 3, or 4 is available, you can use the following steps:

1. Open the Control Panel.

2. Double click the System icon.

3. Choose the Device Manager tab.

4. Highlight the Ports (COM and LPT) branch.

5. Expand the branch to see which ports are installed on the computer.

To install the SM56 ISA modem so that it is accessible through older application software and

DOS programs, COM port 2, 3, or 4 should be available. If none of these ports are available, you

must disable one of the COM ports in the BIOS.

5Installing Modem Hardware

Hardware Installation:

Install the modem card as follows.

1. Power down the personal computer.

2. Locate a vacant bus connector (ISA or PCI, depending on your hardware) and insert the modem

card.

3. If using the SM56 Data/Fax/TAM/Speakerphone modem, connect the sound subsystem

interface cable(s) to the modem card (via the internal TAPI connector or using the audio jacks

-- refer to the information above on sound card compatibility.)

4. Connect the modem Line input to an analog phone jack using an RJ-11 phone cable. Optionally,

connect a telephone handset to the Phone input on the line interface card. The external

telephone cable connections are as follows.

5. Replace the personal computer cover and power the personal computer on.

6Installing SM56 Software

6-1 Installing SM56 Software on Windows 95/98

IPCI Slots

The SM56 for PCI is PCI Plug and Play compliant. It requires one IRQ ( IRQ 3, 4,...15) and one

memory mapped base address.

Windows 95/98 assigns the modem a COM port number. The SM56 installation software attempts

to negotiate a COM port number in the range of 1-4 in order to support older software and DOS

games. Note that the SM56 PCI modem does not include direct DOS box support. Please refer to

the Troubleshooting section for information on how to get around this limitation.

Installing on Windows 95/98

(Note: The Install Wizard may vary slightly with different versions of Windows 95 and Windows

98.)

On starting Windows 95/98 for the first time after installing the SM56 (ISA or PCI) line interface

card, the Windows 95/98 Configuration Manager detects the new hardware, assigns resources to it,

and then displays a window requesting the modem software drivers. This indicates that the

Configuration Manager is looking for the information (INF) file, which contains information about

the modem, including device type (Modem), device driver information (the name of the driver that

will control the modem) and the AT command/response sets that it supports.

In response to the request window, insert the distribution CD-ROM that contains the SM56

installation software. Select Driver from Disk Provided by Hardware Manufacturer. Windows

should find the information on the disk and identify the device as the SM56 Modem Line Interface

Card. It copies the files from the install disk to the computer.

Note: The SM56 install program may display a message box that reports Cannot locate file

_inst32.ex_... If this occurs, browse and re-point the path to the SM56 installation CD ROM

again. Then click OK.

On boards that have voice capabilities (SM56 Data/Fax/Voice models), another device is found

after the modem has been installed. Windows notifies you that it has found a Serial Wave Device

for the modem and prompts for a Wave Device driver. Re-point Install Shield to the SM56

distribution disk, and click OK.

When these two devices are installed, the SM56 Modem Setup program runs.

SM56 Modem Setup for PCI

The modem setup program for PCI does not prompt for user input during installation. It defaults to

USA country code and Domestic English as the language for the Help files. If you wish to change

either of these settings you may do so via the SM56 PCI Control Panel application (see Verifying

Correct SM56 Installation section) after setup is complete. Also, for SM56

Data/Fax/TAM/Speakerphone modems the microphone and speaker gain selections are done via

the Control Panel application (under the Advanced tab). The SM56 PCI Data/Fax/TAM only

modem does not have a Microphone/Speaker Gain selections.

Determining Microphone Gain Setting

If you connect the modem to the sound card through the internal TAPI connector, use the following

procedure to determine the appropriate microphone gain.

Determine whether the sound card has applied any gain to the microphone signal that is presented

at its TAPI

connector.

Note: The SM56 PCI modem (Data/Fax/TAM/Speakerphone only) Control Panel application

provides slider bars so users can fine tune speaker and microphone gains more easily.

6-2 Installing SM56 Software on Windows NT 4.0

Important -- The SM56 software for Windows NT is Data/Fax only, there is no speakerphone

or TAM supported.

Windows NT 4.0 does not fully support plug and play (PnP). Therefore, after installing the modem

board in the computer and booting, the operating system will not automatically recognize that new

hardware is present. You must manually install the modem as follows:

Step 1 -- Install a COM port for the modem

You must install a COM port for the SM56 modem as follows:

1. Open the Windows NT Control Panel.

2. Double click the Ports icon. The Ports window opens.

3. Select Add.

4. Select a COM port number (in the range 1-4 preferably) that is not already installed, and

allocate to it the standard resources as follows:

COM Port IO Address IRQ

13F8 4

22F8 3

33E8 4

42E8 3

5. When your selections are complete click OK.

6. You will be prompted to restart the computer, do not do so yet. Select Don't Restart Now.

7. Close the Ports window.

Step 2 -- Install the SM56 modem software

1. Open the Windows NT Control Panel.

2. Double click the Modems icon....the Install New Modem dialog appears.

3. Click the "Don't detect my modem; I will select it from a list" check box. Then click Next.

4. Click the Have Disk button.

5. Browse to the Windows NT SM56 modem install software. Click misgmodm.inf to highlight it.

Then click Open, then click OK.

6. Select the Motorola SM56 Modem (note that the product name listed will vary depending on

which modem you have -- Data/Fax/, Data/Fax/TAM, etc.) from the list. Click Next.

7. Click the port number selected in Step 1 above to highlight it as the COM port for the modem.

Then click Next. The wizard will now copy all the necessary files and install the SM56 modem on

your PC.

8. When complete, restart the PC to activate and start the COM port and SM56 modem devices.

You are now ready to use the modem.

7Verifying Correct SM56 Installation

Verify that the SM56 software and hardware installation was completed correctly as follows.

Verifying SM56 Software Installation

1. Verify correct COM port selection.

You can check COM port installation through the Modems icon in the Control Panel or through

the SM56 Control Panel application (see below). Normally, the SM56 will install on COM2,

COM3, or COM4. Sometimes, however, depending on your computer system setup or Windows

setup, the SM56 may install on COM5 (or higher).

Although the modem functions correctly on COM5, many Internet Service Provider (ISP) software

applications (such as AOL) do not work if the modem is on a COM port number higher than

COM4. If the SM56 installs on COM5 (or higher), refer to the Troubleshooting section for

assistance.

2. Run simple diagnostic from the SM56 Control Panel.

The SM56 software modem provides an informative Control Panel that reports:

•Modem status: in use/not in use; dialing; negotiating a connection; actual connect rate (updated

in real time during a connection)

•A button to access the on-line User's Guide

The SM56 Control Panel program also provides access to two Windows components:

•COM port and IRQ information

•A diagnostic utility that sends the modem ATI commands and displays the results: software

build, modem type (DF or DFV), and more.

To access the diagnostics option from the Control Panel, click Properties; select the Diagnostics

tab; select the SM56 Modem from the list; and then click More Info. If the driver is properly

installed, a dialog box appears, with responses to the ATI commands as shown in the example

below. Refer to the AT Commands section in the on-line User's Guide for an explanation of ATI

commands.

Verifying SM56 Hardware Operation

To verify correct SM56 modem card hardware operation (up to the isolation transformer), you can

use the following loop back test procedure.

1. Important: Remove the telephone line connector from the modem card.

2. Select Start.

3. Select Programs-->Accessories-->HyperTerminal.

4. Double click the Hypertrm.exe icon.

5. Optionally, select a connection name and icon.

6. In the Connect Using window, select Motorola SM56 modem.

7. Enter a number in the Phone Number box.

8. Select Dial.

9. Select Cancel.

10. Enter AT <cr>.

The response OK should appear.

11. Enter ATS46 = 23 <cr>.

12. Enter AT&T1 <cr> . Wait a few seconds.

13. Type some letters at the keyboard. If the hardware is functioning correctly, the letters you type

appear on the HyperTerminal display.

8Changing the Operating System

Windows 98 Upgrade Error Message

If the SM56 modem is installed on a Windows 95 PC, and then the system is upgraded to Windows

98, the following error message appears when Windows 98 starts:

Duplicated device: vcd

To remove the error, edit the SYSTEM.INI file and locate the line that reads:

Device = *vcd

Delete this line. Save the modified SYSTEM.INI file and restart Windows 98. You will no longer

get the error message.

9Using the SM56 Modem

32-Bit Windows 95/98 Applications

Because 32-bit Windows 95/98 applications use TAPI for communicating with modems, using the

SM56 is as easy as selecting the SM56 modem by name from the list of available modems.

16-Bit Windows 95/98 Applications

Because 16-bit applications cannot use the TAPI interface, there is a bit more setup needed.

1. Select Motorola SM56 modem from the list of supported modems (if the SM56 modem is

not shown, select Hayes Compatible modem).

2. Configure the application's COM port selection. Use the COM port assigned to the SM56

modem.

3. If the application requires it, enter specific AT commands for the SM56 modem. (For a

full list of AT commands, refer to the SM56 on-line User's Guide). Some typical AT

commands are listed below.

DOS-Based Applications and Games

Important: The SM56 PCI modem does not include direct DOS box support. Please refer to the

Troubleshooting sections for information on a way to get around this limitation.

The SM56 ISA modem can be used in DOS only through a Windows 95/98 DOS box.

DOS support is achieved by virtualizing the standard I/O and IRQ assigned to a COM port. This

means that the SM56 drivers capture and redirect all I/O to/from the standard I/O address for the

COM port to which it assigned. In simpler terms, you tell the application the COM port of the

SM56, and then use all the standard I/O and IRQ settings. Standard I/O addresses and IRQs for

COM Ports 1-4 are as follows:

COM Port IO Address IRQ
