Introduction

Thank you for purchasing the Actiontec PCI Pro 56K internal modem. The PCI P ro incorporates the latest technology in controller-less V.90 modems for the PCI bus. This technology improves the performance and capabilities of personal computer fax/modems. The use of the PCI Bus frees the user from having to use an ISA slot which is most likely already being used by another peripheral. Almost every PC has at least one free PCI slot.
Host-based or “Windows” modems utilize your computer’s internal Central P rocess­ing Unit, or CPU to perform some of their functions. The modem’s onboar d digital signal processing circuitry handles the most processor-intensive functions such as V.90 and V.34 modulation, while the CPU handles more routine communications tasks like data compression. This allows for fewer parts and greater reliability without taxing the overall system speed. It also allows the modem greater access to memory and disk storage space. As personal computers advance in speed and capabilities, controller-less modems can take advantage of these improvements. Simply download the new driver, follow the installation instructions, and reboot your system. In this way, the performance of your modem improves as your PC hardware improves.

If you are going to use the Telephone Answering Machine (TAM) functions of the modem and you are running Windows 95, you need to install a software component called Unimodem V. If you have Windows 95 OEM Service Release 2 (Version
4.00.950 B, hereafter referred to in this manual as Windows 95B) or a later version of Windows, this component comes standard as part of the operating system.
To find out which version of Windows 95 you are using, right-click the My Com- puter icon on the desktop, and choose Properties from the menu that appears. If the version of Windows 95 is 4.00.950 or 4.00.950A, go to the UNIMODEM directory of the CD-ROM that came with your modem and right-click on the UNIMOD V .INF icon, (this may be named UNIMODV) then click on Install.. Restart your computer to enable the drivers.
In order to support older software, the modem will always be assigned to COM 4. This port assignment is made by Windows based on instructions contained in the .INF file supplied with the modem. Check Device Manager and verify that COM 4 is not listed.
Right-click on the My Computer icon, choose Properties, and select the Device Manager tab. From the device tree, double-click the Ports [COM & LPT] icon to expand the list of ports. COM 1 and COM 2 should be listed. If COM 4 is listed, it is in use, it must be made available as the modem will be automatically assigned to this port. Highlight COM 4 by clicking once on its listing in device manager, then click Remove. Click Refresh. If the COM 4 listing returns, you have a hardware device using the port. Reinstall the device on another COM port.

For Windows NT 4.0 Installation

Before installing your new modem, be sure to remove any modems and their drivers from your operating system. On the taskbar, click Start. On the Start menu click Settings, then click Control Panel. Double-click the Modems icon. Highlight the modem you wish to remove and click Remove. Turn off the computer and physically remove the old modem. Do not install your new modem at this time. Follow the procedures below to help insure a trouble-free installation. Once you remove the old
modem and its drivers from your system, you will need the old modem driver diskette if you wish to reinstall it at a later date.
Determine that your installation of NT 4.0 is current. Service Pack 3 (or greater), from Microsoft, should be installed. On the Start menu, click Settings then click Administrative Tools then click Windows NT Diagnostics. Select the V ersion folder . Service Pack 3 (or greater) should be stated. If you do not have the latest service pack upgrade installed, it must be obtained from Microsoft. The latest upgrade can be downloaded from the Microsoft web site: www.microsoft.com.

Installing The Modem

Always discharge static electricity before handling your modem. You may discharge static electricity by touching a grounded metal structure or by using any commercially available grounding strap.
Make sure the expansion slot type is 16-bit, which has two slots to fit the ISA card. 8-bit slots have only one connector. If you use an 8-bit slot, the modem will not have access to the higher interrupts (IRQ 9-
12). The position of the expansion slots in your computer may differ from
the illustration shown but the installation procedure should be the same.

Hardware Installation

1. Turn off the computer and all peripheral devices connected to it.
2. Unplug the computer power cord from the wall receptacle.
3. Remove the computer’s cover. Refer to your computer owner’s manual for in­structions.
4. Remove the screw securing the expansion slot cover behind one of the computer ’ s available PCI expansion slots. Lift the expansion slot cover out as shown below.

Installing Communications Software

If your modem came with a communications software package, it is strongly recom­mended that you use this software for your modem. Its default installation param­eters have been specially configured to work with this modem. The Users Guide for this program can be found in Adobe Acrobat (PDF) format on the installation CD­ROM.
Some configurations are packaged without communications software. Check your packaging to see if communications software is included.
If you wish to use another software package, please be sure that it supports this mo­dem. Most Software Manufacturers have a listing of supported modems on their websites or BBSs. Check these sites to see if this model is supported. If you are unsure or your brand of software supports only a few modems, try selecting “Hayes Com­patible” or “Standard Modem”. This may work in certain cases.
Some software programs allow manual input of parameters. For the users of these programs, here is a listing of the Data/Fax/Voice Command Standards supported.
Data: TIA/EIA-602 Fax: TIA/EIA-578 for Class 1 Fax Voice: TIA IS-101 support for TAD (Telephone Answering Device) Init String: AT&F&C1&D2W2
TIA IS-101 Commands not supported: Caller ID
Full Duplex Speakerphone VoiceView
Note: some programs must be configured to communicate with the modem on
the same COM port and or IRQ setting used by the modem. See the “In­stalling the Modem ” for instructions on how to determine your COM port and IRQ settings.
The Modem’s Voice Features
This modem supports TIA IS-101 commands applicable to a Telephone Answering Device. In order to take advantage of this feature, you will need a Sound Blaster compatible sound card equipped with an external microphone and external speakers. A software application which supports these TAD functions (such as the one sup­plied with the modem) is also required.
29
®
Page 31
A modem based Telephone Answering Machine works by using a sound card equipped with a microphone to record an outgoing message. This message is stored as a .wav file which is transferred to the modem by the application program when an incoming call is detected. The modem’s internal electronics conver ts the digital information contained in the .wav file into an audio signal which is then sent over the phone line. The person calling hears your outgoing message and responds with an incoming message.
The sequence of recording an incoming message is the reverse of an outgoing mes­sage. The modem converts the audio signal into a digital format and sends it to the application program. The application program then formats and stores the incoming message as a .wav file. When you play back your stored messages by selecting them from within the application program, they are sent to the sound card. You then hear your recorded messages through the sound card’s speakers.
The default parameters of the software which came with your modem have been specially configured to identify and use your modems voice capabilities. Even if you have decided to use another third-party application, try your included application first. This will allow you to test the modem and its voice functions before inv esting in an expensive retail software package.

Troub leshooting

This section lists some common problems and offers suggestions for a solution. It is important to remember that this modem is a Windows-based modem and requires 32bit virtual device drivers. It therefore cannot work in W indows 3.1 which cannot use these drivers. The modem also cannot work in DOS regar dless of version. It is a software installed device and has no provisions for manual configuration.
If you cannot find your particular symptom listed here, it is suggested that you re­move the modem and its drivers from the system and reinstall them again. (See “Uninstalling the Modem” later in this section.) This provides a “clean” installation and can cure many temporary problems. See “Do This First” for before reinstalling the modem.
Most problems encountered during the Windows 95/98/NT installation process ar e a result of insufficient system preparation. Make sure to physically remove any previ­ously installed modems from your system.
If your modem has installed but is not functioning, try the troubleshooting proce­dure listed below .

Windows 95/95B/98

Step 1: Check System Resour ces
On the taskbar, click Start. On the Start menu, click Settings, then click Control Panels, and double-click the System icon. Select the Device M anager tab. F r om the
device tree, double-click the Modems icon to show what modems are installed. If there is no Modems icon, your modem did not install (See “Does Not Install”.) If your modem is listed, check that there is no yellow exclamation mark or red “X” over the modem’s icon (if there is, go to step 2). If any other modems are listed, highlight the modem by clicking once on the icon next to the listed modem and then click on the Remove button. Turn off the system. Wait 5 seconds and turn your computer back on and repeat step 1.
Step 2: Check Modem Pr operties
In the Device Manager tab of System Properties, double-click the Modems icon to show what modems are installed. Highlight your modem by clicking once on the icon and then click the Properties button. Read the Device Status under the General tab to see if the device is working properly. Check the Device Usage area and make sure “Disable in this hardware profile” ( Windows 95B and 98 only) or the box la­beled “Original Configuration, Current” has a check mark (for Windo ws 95 or 95A.)
31
Page 33
If either of these conditions are present, correct them. Make a note of the Com port and IRQ the modem is using. If the Device Status area shows some error message, it will generally be about a conflict. Go to the Resources tab and read the Conflicting Device List. If a conflict is present, click to deselect “Use automatic settings” and select a configuration that does not cause conflicts. Manually change the IRQ set­tings if needed (see your Windows 95 or 98 on-line help file for a more detailed discussion on changing these settings). Click the OK button. If there is no setting free of conflicts, See “Does Not Install.”
Step 3: Modem Diagnostics
On the taskbar, click Start. On the Start menu, click Settings, then click Control Panel and double-click the Modems icon. Y our modem should be listed. If any other
modem is listed, click once on each old modem and then click the Remove button. It is a good idea to turn off your computer, wait 5 seconds and turn the power back on. Return to Modems and click the Diagnostics tab. Highlight the modem by clicking once on the COM port icon next to its listing. Now click the More Info button. You should see the panel below.
Figure 8: More Info P anel
If you receive an error message or the panel is blank, see “Does Not Install” section.
32
Page 34
Step 4: Does Not Install
The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ resources. The modem needs one IRQ and two I/O addressees in order to function. Modern computer systems are usually equipped with sound card, CD-ROM drive, Hard-drive, floppy drive, video card, two COM P orts, one LPT port, keyboard, and a mouse. Each of these devices require at least one IRQ (interrupt) in order to func­tion.
This section deals with the process of freeing IRQ’s and configuring the system for Plug-N-Play requiring that you know how to enter your computer system’s BIOS Setup Routine (read your computer user’s manual for information on how to invoke and use the BIOS setup).
Once inside the BIOS Setup, find the Plug-N-Play configuration. This can be found within the “Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configura­tion” section depending on the BIOS Manufactur er . Next, from the information you noted in Step 2. Find the interrupt selection for the IRQ your modem is using. (Some BIOSs do not allow individual selection of interrupts to ISA, Plug-N-Play , or PCI.) Y ou want to set this so that the PCI bus has access to this interrupt. This can be called ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer. Do not set this interrupt to “ISA” only or to “Legacy ISA”.
If you do not have any free interrupts available, you will have to disable some unused function of your computer system. If you are using a PS/2 style mouse, you may be able to spare one of your internal COM ports. To disable a COM port, find the BIOS Setup section for “Integrated Peripherals”. Locate the Serial Port settings and disable an unused port that has nothing connected to it This will often be serial port
2. This should free one IR Q for your modem to use. You may also have to disable the
COM Port in Windo ws. Although it is possible for a PCI card to share interrupts, it is recommended that you
have one free IRQ available in your computer. The modem needs one IRQ and two I/O Addresses to function. To check for any available interrupts in your system, right-click on the My Computer icon, choose Properties, and select the Device Man- ager tab. Click the Properties button to view the System Resources.
Their are 16 (0-15) interrupts available in a system. Make a note of any interrupt not listed. To make sure that an available interrupt is assigned to the PCI bus, go to your system BIOS Setup routine and find the Plug-N-Play settings. These are found in the “Advanced”, “PNP/PCI Configuration”, or “Plug and Play Configuration” sections depending on the BIOS Manufacturer.
Next, verify that one fr ee IRQ has been set so that the PCI bus has access to it. (Some
33
Page 35
BIOSs don’t allow individual selection of interrupts for ISA, Plug-N-Play, or PCI.) The interrupt settings can be called “ICU”, “ICU/PCI”, “PCI”, or “PNP depending on your BIOS version and manufacturer. Do not set this interrupt to “ISA” only or to “Legacy ISA”. Be sure to Save the settings before exiting the BIOS Setup.
Under some situations, you will find that freeing an interrupt does not solve your installation difficulties. This could be due to another peripheral device stealing the interrupt you just provided. Certain full-featured sound cards require three IRQs to support all their functions. When one becomes available, they take it. This situation requires that you remove your sound card, free an interrupt, install the modem and verify its operation, and then reinstall the sound card. This procedure may also work for sound cards that have lost their sound after the modem has been installed or if the modem will not install in a system with a sound card.
Proceed to “Installing the Modem”.

Windows NT installation problems are always due to inadequate preparation. The following conditions must be meet before attempting to install the modem or it will not be seen or correctly installed by the system. (See “Do This F irst” at the beginning of this manual.)
You must have the latest Windows NT Service Pack installed.
There must be two IRQ and two I/O port Addresses available for the modem to
use.
The installation utility must be copied from the installation CD-ROM to the
default hard drive and extracted.
If you need help on freeing an interrupt or making a COM Port available, see the Windows 95/98 “Does Not Install” section for a discussion of this topic. The “Spe­cial Situations” and “Plug-N-Play BIOS” sections also apply to Windows NT 4.0. See these areas for guidelines. If you are upgrading or removing the drivers, use the installation utility on the Windows NT installation diskette that came with your PCI modem. This utility has an option for removing the modem drivers.
If you are not familiar with changing the settings within your system BIOS setup, you should skip the following system pre-installation procedure and go to “Installing the Modem.” Refer back to this area only if you have a problem installing the mo­dem.
Check your system BIOS IRQ assignments and make sure that at least two interrupts have been assigned to the PCI bus. In your system’s BIOS Setup routine, find the
34
Page 36
Plug-N-Play settings. These settings can be found within the “Advanced,” “PNP/ PCI Configuration,” or “Plug-and-Play Configuration” sections depending on the BIOS Manufacturer . Next, verify that at least two IR Qs have been set so that the PCI bus has access to them (some BIOS don’t allow individual selection of interrupts to ISA, Plug-N-Play, or PCI). These settings can be called ICU, ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer. Do not set all the inter­rupts to “ISA” only or to “Legacy ISA”. Pay attention to the IR Q usage of the other peripherals in your system. Do not reassign an interrupt that is already in use by an ISA card to the PCI bus.

Common Problems

No Dialtone Error
Make sure you have connected the phone cable into the right connector on the back of the modem. See Figure 7.
Y ou may have too many devices connected to the phone line. Remove all other equip­ment.
Your modem may not recognize overseas dialtone. Use the AT command ATX0 to have the modem ignore (not look for) the dialtone before dialing. (See Appendix A for information on how to use AT commands.)
Communications Software Does Not W ork
Some communications software packages need to be configured to the same COM port and or IRQ as the modem. See the “Installing the Modem” for information on how you determine your COM Port and IRQ number.
Does the communications software support this modem? See the Installing and Con- figuring Communications Software section.
If you are using a different software from the one supplied with the modem (some models of this modem may be shipped without communications software), try in­stalling the supplied software and verify its functionality with the modem.
Nothing Appears On The Screen When I Type
Issue the AT command ATE1 to the modem to enable command echo. This will let you see what you type.

Can’t Connect at 56K
Note: Current FCC regulations limit your maximum connection rate to 53Kbits / s. The number you are calling may not support V.90 or K56flex protocols. Some ISPs
(Internet Service Provider) have special numbers that you must call to connect to 56K. Contact your service provider and ask if the number you are calling supports V.90 or K56flex connections to their service.
Check the maximum speed setting in the Modem Properties window. On the task­bar, click S tart. On the Start menu, click Settings, then click Control Panels. Double- click the Modems icon. Highlight your modem by clicking once on the icon next to the modem and then click the Properties button. Select the General tab and look at the setting in the Maximum speed box. Make sure this is set to 115200.
You may have other telephone devices connected to the phone line. To help your modem achieve the best connection possible, remove all extra devices and their cables from the telephone line when the modem is in use. This reduces the load on your phone line and keeps signal attenuation to a minimum.
Keep the length of your phone line cable to 10 feet or less. Don’t use an unusually long cable to connect to the phone line socket. If necessary, move the computer closer to the phone socket. Don ’t lay your cabling close to an electrical appliance like a refrigerator or air conditioner unit. High current devices can transmit a 60 cycle “hum ” to your modem thr ough the phone cor d. This may cause frequent renegotia­tions or line disconnects while the appliance is running.
The telephone line conditions at the time of your call may not let you connect at 56K. The modem has a connection sequence of K56flex, then V.90, then V.34, and so on. The modem attempts to make the highest connect rate that your telephone line can support at the time of negotiation. If the line conditions (noise, telephone company routing, etc.) won ’ t allow a high data rate connection, then the modem will automatically connect at the most reliable rate. Try making the call again after a few minutes. The routing of the call may improv e your chances of making a 56K connec­tion.
If you are attempting to make a call from an office, are you using a direct outside line or are you using a PBX hookup? If you have to dial “9” to reach an outside number , you are using a PBX. The modem cannot connect faster then V.34 if you are using a PBX. Try using the line that is connected to a fax machine. Fax machines are usually connected to a dedicated line and not through the PBX.
Y our phone line may not support a 56K connection. Or may support a 56K connec­tion only intermittently. There are many conditions that must be met before a 56K
36
Page 38
connection can be established. The telephone company must have you connected to the PSTN (Public Switched Telephone Network) in a particular way. The modem you are calling must support the same protocol. The phone line must be free of distortion and noise. The phone wiring in your house or building must be in good condition and so on. Check to see if you have good voice communications while talking to friends or relatives. Do their voices sound distorted? Do you hear a “hiss­ing” or “humming” sound in the background? I s there “ popping ” or “ crackling” dur­ing your call? These are phone line problems. In the case of distortion, your phone line is bad. Humming may be due to the cabling inside your residence coming too close to a high current appliance or you may have a cordless phone recharger base connected to the phone line. Popping or crackling usually indicates a loose connec­tion to the outside line or water dripping on the hookup outside your house.
The drivers for your modem are constantly being refined to address problems with compatibility, interoperability, and performance. Check the Actiontec website on a regular basis for driver upgrades. A problem connecting to a particular provider might be fixed by a simple software upgrade.

Uninstalling the Modem

If you are uninstalling the modem in Windows 95 or 98 in order to upgrade your drivers or obtain a clean reinstallation, it is important to follow these directions care­fully .
When removing the drivers from a system running Windows NT, use the installation utility. The utility has an option to remo ve your modem drivers.
Uninstalling in Windows 95 and 98
Step 1 On the desktop, right-click the My Computer icon and choose Properties
from the menu that appears. Select the Device Manager tab. D ouble-click the Modems icon to expand the M odems section of the list. Highlight your modem by clicking once on its icon, then click Remove.
Step 2 On the taskbar, click Start. On the Start menu, click Settings, then click
Control Panel and double-click the Modems icon. If your modem is listed, highlight the modem by clicking once on the icon next to the modem and then click the Remove button. Or, if the New Hardware dialog box comes up, click Cancel.
Your modem should not be listed in the Modems section after you have deleted it from the Device Manager. This could be a sign that your Plug-N­Play settings are not correct. See “Does Not Install” for more information about Plug-N-Play.
37
Page 39
Step 3 Close all open windows and return to the desktop. On the taskbar, click
Start. On the Start menu, click Find, then click F iles or F olders. Search for the files listed below. Type in the name and extension (e.g. ltwave.inf) and click the Find button. Once you find each of the files listed, highlight the file by clicking once on the file name and then, in the Find All Files dialog box, click to show the File menu and choose Delete. Delete all occurrences of these files in your system.
ltcom.vxd ltwave.inf ltmodem.vxd ltdfv.inf ltvcd.vxd ltdt.inf ltmodem.sys ltports.inf ltdsvd.dll
If you cannot find a particular file, it usually means it was not installed. After all instances of these files have been deleted, restart your system.
Note to users of Windows 95 and 98
If you are using Windows 95B (see “Do This F irst” for instructions on how to deter­mine your Windows 95 version), you need only delete the files listed. In the case of Windows 95 or Windows 95A, there are two additional files which Windows 95 or Windows 95A generates when installing a third-party hardware peripheral. The file is called oem#.inf. The number (#) used is generated by Windows 95 each time an additional piece of hardware is installed. In the case of the modem, these files could have any number between 1 and 99--oem8.inf, for example.
Close all open windows and return to the desktop. On the taskbar, click Start. On the Start menu, click Find, then click Files or F olders. T ype in *.inf in the N amed box. Make sure your entire drive is selected and not just one subdirectory. Place a check mark in the Include subfolders box. Be sure all the information is typed in as shown below. Before beginning the search, click the Advanced tab.
38
Page 40
At the Advanced settings window, type the following in the Containing text field: V.90 PCI Windows Modem. Click Find Now.
When a file is found, it will have the name oem#.inf. To delete a file, highlight the file name by clicking once and then choose Delete from the File menu.
Next, go to the Advanced tab and type the following in the Containing text field: V.90_PCI_Windows_Modem as shown below.
After Windows finds the other file, delete it as before. Restart your system and follow the installation procedures outlined in the “Installing the Modem.”

AT Command Set

AT Commands

AT commands are issued to the modem to control the modem’s operation and soft­ware configuration. AT commands are commonly entered from a terminal program such as HyperTerminal, and can only be entered while the modem is in command mode. To enter an AT command, type:
ATXn
where X is the AT command, and n is the specific value for that command. Press ENTER.
Commands are acknowledged with either text or numeric value response known as a result code. In the case of multiple AT commands on the same command line, the commands are executed in the order they are received. Should execution of a com­mand result in an error, or a character not be recognized as a valid command, execu­tion is terminated, the remainder of the command line is ignored, and the ERROR result code is issued. If all commands execute correctly, only the result code associ­ated with the last command shall be issued, even though all have been executed.
In the following listing all commands and command values accepted by the modem are shown. Any entries other than those shown cause the ERROR result code.
+++ Escape sequence
The escape sequence allows the modem to exit data mode and enter on-line com­mand mode. While in on-line command mode, you may communicate directly to your modem using AT commands. Once you are finished, you may return to data mode using the ATO command. A pause, the length of which is set by the Escape Guard T ime S-Register (S12--S ee the “S-Registers R eference ” section of this manual for details), must be used after an escape sequence is issued. This pause prevents the modem from interpreting the escape sequence as data. The value of the escape se­quence character may be changed using Register S2.
A/ Repeat Last Command
This command repeats the last command string entered. Do not precede this com­mand with an AT prefix or conclude it by pressing Enter.
A Answer Command
This command instructs the modem to go off-hook and answer an incoming call.

Bn Communication Standard Setting
This command allows you to choose between CCITT and Bell standard.

Dn Dial
This command instructs the modem to begin the dialing sequence. The dial string (n, including modifiers and the telephone number) is entered after the ATD com­mand.
A dial string can be up to 40 characters long. Any digit or symbol (0-9, *, #, A, B, C, D) may be dialed as touch-tone digits. Characters such as spaces, hyphens, and pa­rentheses do not count, they are ignored by the modem and may be included in the dial string to enhance readability.
The following characters may be used as dial string modifiers:

S-Registers Reference

S-registers generally affect how the A T commands perform. Contents of the registers can be displayed or modified when the modem is in command mode.
To display the value of an S-register:
TYPE: ATSn? where n is the register number. Press ENTER. To modify the value of an S-register:
TYPE: ATSn = r where n is the register number, and r is the new register value. Press ENTER.
S0 Auto Answer Ring Number
Range: 0−255
Default: 0
Units: rings This register determines the number of rings the modem will count before automati-
cally answering a call. Enter 0 (zero) if you do not want the modem to automatically answer at all. When disabled, the modem can only answer with an ATA command.
S1 Ring Counter
Range: 0−255
Default: 0
Units: rings This register, Ring Counter, is read only. The value of S1 is incremented with each
ring. If no rings occur over a six second interval, this register is cleared.
S2 AT Escape Character (user defined)
Range: 0−255
Default: 43
Units: ASCII This register determines the ASCII valued used for an escape sequence. The default is
the + character. The escape sequence allows the modem to exit data mode and enter command mode when on-line. Values greater than 127 disable the escape sequence.
67
Page 69
S3 Command Line Termination Character (user defined)
Range: 0−127, ASCII decimal
Default: 13 (carriage return)
Units: ASCII This register determines the ASCII values as the carriage return character . This char­acter is used to end command lines and result codes.
S4 Response Formatting Character (user defined)
Range: 0−127, ASCII decimal
Default: 10 (line feed)
Units: ASCII This register determines the ASCII value used as the line feed character. The modem
uses a line feed character in command mode when it responds to the computer.
S5 Command Line Editing Character (user defined)
Range: 032, 127
Default: 8 (backspace)
Units: ASCII This register sets the character recognized as a backspace and pertains to asynchro-
nous only . The modem will not recognize the backspace character if it is set to a value that is greater than 32 ASCII. This character can be used to edit a command line. When the echo command is enabled, the modem echoes back to the local DTE the backspace character, an ASCII space character, and a second backspace character. This means a total of three characters are transmitted each time the modem processes the backspace character.
S6 Wait Before Dialing
Range: 2-65
Default: 2
Units: seconds This register sets the length of time, in seconds, that the modem must wait (pause)
after going off-hook before dialing the first digit of the telephone number. The mo­dem always pauses for a minimum of two seconds, even if the value of S6 is less than two seconds. The wait for dial tone call progress feature (W dial modifier in the dial string) will override the value in register S6. This operation, however , may be affected by some ATX options according to country restrictions.
68
Page 70
S7 Connection Completion T ime-Out
Range: 1-255
Default: 50
Units: seconds This register sets the time, in seconds, that the modem must wait before hanging up
because carrier is not detected. The timer is started when the modem finishes dialing (originate), or goes off-hook (answer). In originate mode, the timer is reset upon detection of an answer tone if allowed by country restriction. The timer also specifies the wait for silence time for the @ dial modifier in seconds. S7 is not associated with the W dial modifier.
S8 Comma Dial Modifier Time
Range: 0-65
Default: 2
Units: seconds This register sets the time, in seconds, that the modem must pause when it encoun­ters a comma (“,”) in the dial command string.
S10 Automatic Disconnect Delay
Range: 1-254
Default: 20
Units: 0.1 seconds This register sets the length of time, in tenths of a second, that the modem waits
before hanging up after a loss of carrier. This allows for a temporary carrier loss without causing the local modem to disconnect. The actual interval the modem waits before disconnecting is the value in register S10.
S11 DTMF Dialing Speed
Range: 50-150
Default: 95
Units: 0.001 seconds This register determines the dialing speed which is prefixed for each country.
S12 Escape Guard Time
Range: 0-255
Default: 50
Units: 0.02 seconds This register sets the value (in 20 ms increments) for the required pause after the
escape sequence (default 1s).

S24 Timer to Control Sleep Mode
Range: 0, 5-255
Default: 10 This command displays the number of seconds of inactivity (no characters sent from
the DTE, no RING) in the off-line command state before the modem places itself into standby mode. A value of zero prevents standby mode.
If a number between 1 and 4 is entered for this register , it will set the value to 5, and the inactivity before standby will be 5 seconds. This is done for compatibility with previous products which allowed time-outs down to 1s.
S28 V .34 M odulation Enable/Disable
0 = disabled, 1-255 = enabled,
Range: 0-255
Default: 1 This register enables/disables V.34 modulation.
S30 Inactivity Timer
Range: 0-255

Units: minutes S30 specifies the length of time (in minutes) that the modem will wait before discon-
necting when no data is sent or received. This function is only applicable to buffer mode.
S32 Synthetic Ring Volume
Range: 0-255
Default: 10 This register specifies a synthetic ring volume in dB with an implied minus sign.
S33 Synthetic Ring Frequency
Range: 0-5
Default: 0 This register specifies a synthetic ring frequency. Valid ranges are 0-5, with 0= dis-
abled and 1-5 corresponding to 5 ring frequencies.
71
Page 73
S35 Data Calling T one
0 = disabled, 1 = enableD
Range: 0-1
Default: 0 Data Calling Tone is a tone of certain frequency and cadence as specified in V.25
which allows remote Data/FAX/Voice discrimination. The frequency is 1300 Hz with a cadence of .5 s on and 2 s off.
S36 Negotiation Fallback (default 7)

S36 = 0, 2 Hang up.
S36 = 1, 3 Fall back to an asynchronous connection.
S36 = 4, 6 Attempt MNP. If MNP fails, hang up.
S36 = 5, 7 Attempt MNP. If MNP fails, fall back to asynchronous
connection.
S37 Dial Line Rate (default 0)
S37 = 0 maximum modem speed S37 = 1 reserved S37 = 2 1200 bits/s and 75 bits/s S37 = 3 300 bits/s S37 = 4 reserved S37 = 5 1200 bits/s S37 = 6 2400 bits/s S37 = 7 4800 bits/s S37 = 8 7200 bits/s S37 = 9 9600 bits/s S37 = 10 12000 bits/s S37 = 11 14400 bits/s S37 = 12 16800 bits/s S37 = 13 19200 bits/s S37 = 14 21600 bits/s S37 = 15 24000 bits/s S37 = 16 26400 bits/s S37 = 17 28800 bits/s S37 = 18 31200 bits/s S37 = 19 33600 bits/s
72
Page 74
S38 56K Dial Line Rate (default 1)
There are 2 S-registers which support K56flex connections. S38 sets the maximum 56K downstream speed that the modem attempts to connect. To disable K56flex, set S38 to 0. The S37 register is used to control the upstream V.34 rate. (ref. V.34 Data/ Fax Document). Use the S109 register to control V.90 connections.
S38 = 0 K56flex disabled - V.34 connection (see S37) S38 = 1 K56flex autorate - maximum achievable connection S38 = 2 32000 bits / s S38 = 3 34000 bits / s S38 = 4 36000 bits / s S38 = 5 38000 bits / s S38 = 6 40000 bits / s S38 = 7 42000 bits / s S38 = 8 44000 bits / s S38 = 9 46000 bits / s S38 = 10 48000 bits / s S38 = 11 50000 bits / s S38 = 12 52000 bits / s S38 = 13 54000 bits / s S38 = 14 56000 bits / s
S42 Auto Rate (default 1, range 0-1)
0 = auto rate disabled, 1 = enabled.
Range: 0-1
Default: 1 This command is used for testing and debugging only . V.32bis and V .22bis auto rate
is disabled. Retrain operation is disabled or enabled in data mode, and fallback is disabled in data mode. S43 Auto Mode (default 1, range 0-1)

the DTE, no RING) in the off-line command state before the modem places itself into standby mode. A value of zero prevents standby mode.
If a number between 1 and 4 is entered for this register , it will set the value to 5, and the inactivity before standby will be 5 seconds. This is done for compatibility with previous products which allowed time-outs down to 1s.
S90 Local Phone Status
0 = local phone on-hook
1 = local phone off-hook This register tells the status of the local phone. It is read only.
S91 Line Transmit Level
Range: 6-15
Default: 15
Units: 1 dB This register is effective only for Japan. It specifies the line transmit level in dB with
an implied minus sign.

S92 Direct Connect Transmit Level (default 20)
Sets the transmit level, in dBm for direct connect. This value may have different settings for different phones.
