Section 3 Configuration Utility 7 Xircom Inc. Mini PCI User’s Guide Section 3 Configuration Utility This section described how to use the Configuration Utility for the Mini PCI adapter. Introduction The WLAN Mini PCI adapter enables high-speed access to internet and intranet assets without wires. This card uses the IEEE 802.11 protocol to enable communications between the host computer and either another host computer or a network, using the 2.4GHz ISM Radio Band for the communications medium. The host computer uses the adapter for communications in the same way that it would use an Ethernet Network Interface Card (NIC). The Configuration Utility is a Windows application that allows the user of a computer equipped with a adapter to configure the adapter and to display the current configuration for the adapter.

8 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc Installing the Configuration Utility The Configuration Utility is installed simultaneously with the adapter driver by executing the utility for the Windows.exe file. The following dialog shows the first dialog. 1. Click the Finish button to install the driver and the Configuration Utility on your computer System Tray Icon After the installation of the Configuration Utility, an icon appears in the System Tray in the bottom right corner of your desktop. The red, yellow and green colors of the icon indicate the link status. Red indicates no or very poor link quality. Yellow indicates a usable but weak link. Green indicates a strong link.

10 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc Starting the Configuration Utility You can launch the Configuration Utility either by double-clicking (with the left mouse button) on the Configuration Utility icon or by right clicking on the Configuration Utility icon and selecting Advanced Configuration… If the Configuration Utility icon is not displayed in the System Tray, you can restart the Configuration Utility from the Start Menu by selecting Programs and Configuration Utility. The Configuration Utility consists of four menus: Configuration, Encryption, Link, and About. The following sections describe these menus in detail. Configuration Menu The Configuration menu lets you specify the operating parameters for your adapter. When you first start the Configuration Utility, this menu is displayed. If another menu is displayed, you can display the Configuration menu by clicking on its tab in the Configuration Utility panel.

12 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc 802.11 AdHoc Mode IEEE 802.11, the standard on which the WLAN protocol is based, defines two modes to handle two separate needs. The first, called AdHoc (or IBSS) mode, is used when two or more wirelessly-enabled PCs wish to exchange data directly, without an Access Point. In this case the PCs can establish an AdHoc network in which they are the only members and over which they can exchange data. To exchange data, each computer participating in the AdHoc network must also specify the same SSID and AdHoc Channel in this menu. Infrastructure Mode The second mode defined by the IEEE 802.11 standard is called infrastructure mode, and is the primary application for WLAN operation. In this mode all data on the wireless network is directed to an Access Point, which then routes the data to the appropriate wireless station. The Access Point may also be configured to allow data to be bridged from the wireless network to wired networks. To participate in a wireless LAN in infrastructure mode, every station and Access Point must specify the same SSID. In infrastructure mode, all available channels are scanned for traffic, so there is no need to specify a channel. Pseudo AdHoc A third mode has been defined by Intersil, and is used mainly for testing purposes. Pseudo AdHoc mode allows computers to communicate even without exchanging compatibility data. For instance, you can send broadcast frames in this mode over a given channel and expect no interruption by beacons or other packets not involved in the test. This mode can be used for Packet Error Rate Testing, for example, to evaluate performance. As with AdHoc mode, each computer participating in the Pseudo AdHoc network must also specify the same SSID and AdHoc Channel in this menu. However, note that this mode can only be used to communicate with other adapter. Setting the SSID The SSID is the Service Set IDentifier used by Access Points and stations to identify a wireless LAN. Your PRISM WLAN Interface card scans the available channels looking for an Access Point (in infrastructure mode) or another station (in AdHoc mode) which has specified this same SSID. It then attempts to associate with these Access Points or stations to form a wireless LAN. To change the SSID, simply highlight it, type the new SSID, and click the Apply button. In typical infrastructure applications a company will use a single SSID for all Access Points. If the radio is scanning and cannot find a channel when an Access Point is known to be in range, verify that the SSID is set correctly. Setting the Transmit Rate The Transmit Rate field specifies the rate at which the radio in your adapter’s transmits and receives data. You can view the available rates by clicking the down arrow at the right of the Transmit Rate field.

Section 3 Configuration Utility 13 Xircom Inc. Mini PCI User’s Guide The transmit rate can be set to: • Fully Automatic – your adapter chooses the highest available rate providing reliable communications based on the capabilities of the Access Point or station with which it communicates and on the received signal quality • Auto 1 or 2 Mb – allows only 1 and 2 Mb/s operation • 5.5 Mb – allows only 5.5 Mb/s operation • 11 Mb – allows only 11Mb/s operation To change the Transmit Rate, click the down arrow at the right of the field, highlight the rate you want to set, and click the Apply button. Under most conditions, you should choose Fully Automatic as the transmit rate. In general, fixed rates are used only in test environments. Enabling Power Save Mode The IEEE 802.11 standard provides a Power Save Mode. In this mode your adapter listens for a beacon (a periodic frame which defines the network type and attributes) and determines the beacon interval. Between beacons the card puts itself to sleep, enabling power savings. At the time of the expected beacon the card wakes itself up and receives the beacon. The received beacon contains information about whether the Access Point or station has buffered frames for the card. If frames are available the card requests those frames until no more frames are available. The card then goes back to sleep until the next beacon. For Access Points that support power save mode and for stations equipped with WLAN cards, enabling this mode can significantly reduce power consumption, which is particularly important if the host computer is operating on battery power. However, be aware that power save mode also results in lowered transmission and reception speed on the wireless LAN.

14 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc Selecting the Ad Hoc Channel When communicating in AdHoc or Pseudo AdHoc mode, you must specify a channel on which communications will take place. To specify a channel, click the up or down arrow at the right of the AdHoc Channel field until the channel you want to set appears, and then click the Apply button. This field is grayed in infrastructure mode because the channel is automatically selected by the Access Point. Encryption Menu The Encryption menu lets you enable encryption and set the encryption keys. To see the available encryption methods, click the down arrow at the right of the Encryption {WEP} field. There are two encryption methods available. The IEEE 802.11 specification defines Wired Equivalent Privacy (WEP) using a 64-bit key. This capability was extended by the industry to allow a 128 bit key. If you specify an encryption method, you will only be able to communicate with Access Points and stations that use the same encryption method and keys.

Section 3 Configuration Utility 15 Xircom Inc. Mini PCI User’s Guide Disabling Encryption To disable encryption, click the down arrow at the right of the Encryption field, select Disabled, and click the Apply button. Enabling Encryption To enable encryption, click the down arrow at the right of the Encryption field, select either 64 bit or 128 bit, and click the Apply button. After enabling an encryption method, you must then specify encryption keys, as described in the following sections. Creating Encryption Keys Using a Passphrase To create encryption keys using a passphrase, click the radio button next to Create Key with Passphrase and type a character string in the Passphrase field. As you type, the Configuration Utility uses an algorithm to generate four keys used for encryption. When you finish typing your character string and click the Apply button, the Configuration Utility uses asterisks to mask both your passphrase and the keys it generates. Using a passphrase to generate the four keys makes it easy to set the same keys for all members of your wireless LAN.

16 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc Creating Encryption Keys Manually If you want, you can create encryption keys manually by clicking the radio button next to Create Key Manually, as shown in the following illustration. When you click this button, the cursor appears in the field for Key 1. For 64-bit encryption, you must type exactly 10 hexadecimal digits in each of the four key fields; for 128-bit encryption, you must type exactly 26 hexadecimal digits. You then click the Apply button to create your encryption keys. After you click the Apply button, the Configuration Utility uses asterisks to mask your keys. Default Key The Default Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the down arrow at the right of this field, selecting the number of the key you want to use, and then clicking the Apply button. As long as the Access Point or station with which you are communicating has the same key in the same position, you can use any of the keys as the default.

Section 3 Configuration Utility 17 Xircom Inc. Mini PCI User’s Guide Link Menu The Link menu provides information on the status of your communications with the wireless LAN. The fields in this menu provide the following information: • State: shows the association state of your computer with the wireless LAN. The above illustration shows that your computer is associated with an Access Point and gives the Access Point’s MAC address. • Current Channel: shows the channel on which the connection is made. In Infrastructure mode, this number changes as the radio scans the available channels. • Current Tx Rate: shows the highest transmit rate of the current association. • Throughput: shows the short term transmit and receive throughput in bytes/second continuously updated. • Link Quality: is based on the quality of the received signal of the Access Point beacon. • Signal Strength: is based on the received signal strength measurement of the baseband processor of the Beacon signal. You can click the Rescan button to force the radio to rescan all available channels. If your link quality or signal strength is poor, rescanning can be used to push the radio off a weak Access Point and search for a better link with another Access Point.

18 Configuration Utility Section 3 Mini PCI User’s Guide Xircom Inc About Menu The About menu provides information on the version of the Network Driver, the Configuration Utility, and the firmware in the adapter. In addition, this menu also provides the MAC address of the adapter.

Appendix A Modem AT Commands 19 Xircom Inc. Mini PCI User’s Guide Appendix A Modem AT Commands This section provides the following information: • Introduction to Modem AT Commands • Special Commands • AT Command Reference Introduction to Modem AT Commands Modem AT Commands With the exception of the Special Commands, all commands must be preceded by the AT attention code (or command prefix) and terminated by pressing the Enter key. The modem responds with the result code OK, which means it understands and can execute the command, or with ERROR, which means that the modem does not understand the command or that the command is invalid. The modem must be in command mode when any command other than the online escape sequence is entered. Commands entered when the modem is in online mode are treated as data and transmitted as such to the modem at the other end of the line. Some commands are used in coordination with S-Registers. Special Commands +++ Online Escape Sequence The escape sequence is used to switch to command mode from online mode during a session with a remote modem. Type three "plus signs." The escape sequence is not preceded by the AT command prefix, nor does it require the Enter key. The setting of S-Register S2 determines the ASCII character used. S2=43 is the default (the "+" sign). 0-127 are valid. To disable the command, set S2 to a value greater than 127. Use the ATO ("AT" and letter "O") command to return to online mode. Insert a pause before and after the escape sequence to prevent misinterpretation of the escape sequence as data. Use S-Register S12 to set the length of the pause. A/ Repeat Last Command The A/ command causes the modem to repeat the last command string. The command executes as soon as / is typed. It does not require the AT command line prefix, nor does it need to be followed by Enter.

20 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc AT Command Reference A Answer Typing ATA causes the modem to go off-hook and respond to an incoming call by generating a carrier signal and starting the handshaking process. This must be the only command or the final command in the command line. If the handshaking process is successful and a connection is established, the normal CONNECT message is displayed. If the carrier signal is not detected within the time specified in S-Register S7, a NO CARRIER result code is displayed. Bn Select Communications Standard The ATBn command selects the communication standard (ITU or Bell) to be used by the modem, as follows: B0 Use ITU V.22 at 1200bps. B0 selects ITU V.22 at 1200bps and ITU V.21 at 300bps. B1 Use Bell 212A at 1200bps. B1 selects Bell 212A at 1200bps and Bell 103J at 300bps. B2 Unselect V.23 reverse channel. B3 Select V.23 reverse channel. B15 Selects V.21 when the modem is at 300bps (same as B0). B16 Selects Bell103J when the modem is at 300bps (same as B1). The ATB1 and ATB16 parameter settings are not available in some countries. Defaults are country-specific. Break (Escape) command See Special Commands. Cn Carrier Control The ATCn command, where n is 1, guarantees backward compatibility with communications software that issues the C1 command. C0 is not supported; it may set some modems to "receive only mode." C0 Transmit carrier always off (not supported). C1 Normal transmit carrier switching. Dn Dial A Telephone Number The ATDn command is used to dial a telephone number. The n represents a dial string consisting of dial digits/characters and dial modifiers (see below) and must not exceed 40 characters. Spaces, hyphens, and parentheses can be used for clarity, but they are ignored by the modem. The Dial command can be used for either pulse (rotary) or tone dialing. The dial digits/characters are 0 - 9 A B C D # *. The characters A B C D and the symbols # and * represent specific tone pairs and can be used only when tone dialing. These characters and symbols are ignored when pulse dialing is used. Some countries restrict or prohibit the use of some of these characters. Dial Modifiers Dial modifiers are recognized by the modem only when they are part of a dial string following the ATD command. Possible dial modifiers are: L Redial Last Number Redials last number if used as first character following ATD. Otherwise it is ignored.

Appendix A Modem AT Commands 21 Xircom Inc. Mini PCI User’s Guide P Pulse Dialing Method The P modifier is used with the Dial command to instruct the modem to pulse dial the telephone number that follows. S=n Dial a Stored Telephone Number The S modifier instructs the modem to dial a number that had been previously stored by the use of the AT&Zn=x command. The command to dial a stored telephone number is ATDS=n, where n represents telephone number storage location 0 or 1. For example, ATD P S=1 pulse dials the telephone number written to telephone number storage location 1. , Delay Processing the Next Character When the comma (,) modifier is included as part of the dial string following the ATD command, the modem pauses before processing the next character in the dial string. The duration of the pause is dictated by the contents of S-Register S8. The , modifier is frequently inserted after the digit (usually 9) used to obtain an outside line from a PBX to allow sufficient time for the dial tone to occur before the modem dials the telephone number. The W modifier can be used in place of the comma. Some countries place restrictions on the amount of time a modem may delay during dialing. T Tone Dialing Method The T modifier is used with the Dial command to instruct the modem to tone dial the telephone number that follows. See also the ATT command. W Wait for Second Dial Tone The W modifier instructs the modem to wait for a dial tone before processing the remaining characters in the dial string. ! Hook Flash The ! modifier serves as a switch hook (or hook flash) signal. This causes the modem to hang up (go on-hook) for about 0.5 seconds then return to off-hook (the actual duration of the hook flash varies in different countries). @ Wait for Quiet Answer The @ modifier in a dial string instructs the modem to wait for five seconds of silence after dialing the number. If silence is not detected, the modem sends a NO ANSWER result code to the user. ; Return to Command Mode after Dialing The semicolon (;) dial modifier can be used only at the end of a command line, immediately preceding the Enter, and instructs the modem to return to the command mode immediately after dialing and without breaking the connection with the distant modem.

22 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc ^ Disable Data Calling Tone Transmission The ^ modifier in a dial string disables data calling tone for the current call (calling tone is automatically enabled in many countries). This modifier is not available in all countries. $ Credit Card Tone Detect The $ modifier in a dial string instructs the modem to wait for a credit card "bong" tone before processing the remaining characters in the dial string. En Echo Command The ATEn command, where n represents 0 or 1, determines if the commands you issue through the keyboard to the modem in command mode are displayed (echoed) on your computer's monitor screen. E0 Disable echo to the computer. E1 Enable echo to the computer (default). If the commands you type are not displayed on your monitor screen, your software is set to expect character echo from the remote system. You can remedy this by typing in the command ATE1. If the commands you type are displayed on your monitor with the characters duplicated, LLIIKKEETTHHIISS, type in the ATE0 command. Hn Switch Hook Options The ATHn command hangs up the modem or prepares it for dialing. ATH0 Causes the modem to go on-hook (default). ATH1 Causes the modem to go off-hook (this command is restricted in some countries). In Request ID Information The ATI command has various options which are used to instruct the modem to provide specific information about itself. I0 Displays modem controller firmware revision (same as I3). I1 Calculates ROM checksum and displays it on the DTE (for example, 12AB). I2 Performs a ROM check and calculates and verifies the checksum. displaying OK or ERROR.. I3 Displays modem firmware revision information. I12 Returns country code (for example, North America). Ln Monitor Speaker Volume The ATLn command, where n represents 0, 1, 2, or 3, is listed here for backward compatibility reference only. The volume of the monitor speaker is controlled by the computer, not by the modem.

Appendix A Modem AT Commands 23 Xircom Inc. Mini PCI User’s Guide Mn Speaker On/Off Selection The ATMn command, where n represents 0, 1, 2, or 3, enables or disables the transmission of sound signals from the modem to the computer speaker. (Sound production also requires that the computer speaker be enabled.) M0 Speaker always off. M1 Speaker on until data carrier is detected. M2 Speaker always on when modem is off-hook. M3 Speaker off as digits are dialed, then on after dialing until data carrier is detected. Nn Negotiation of Handshaking Options The ATNn command, where n represents 0 or 1, determines whether or not the sending modem performs a negotiated handshake when the speed of the answering modem is different from that of the sending modem. N0 When originating or answering, handshake only at the communication standard specified by the contents of S-Register S37 and the ATBn command option selected. N1 When originating or answering, handshake only at the communication standard specified by the contents of S-Register S37 and the ATBn command option selected. During handshaking, fall back to a lower speed, if required (default). On Online Command If the modem has been switched to command mode, typing in the ATO0 command will return it to the online mode with the existing connection. O0 Instructs modem to leave online command mode and return to data mode (see +++ Escape Sequence under Special Commands). O1 This setting issues a retrain command before returning to online data mode. O2 This setting issues a rate negotiation command before returning to online data mode. P Select Pulse Dialing The ATP command instructs the modem to use pulse (rotary) dialing. This mode will remain in force for all dialing procedures unless an ATT command is issued or the dial string contains a T dial modifier. Qn Result Code Display Options The setting of the ATQn command, where n represents 0 or 1, determines whether or not result codes (such as OK, CONNECT, RING, NO CARRIER, and ERROR) are displayed on your PC's screen. Q0 Display of result codes enabled. Q1 Display of result codes disabled.

24 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc Repeat command See Special Commands. T Select Tone Dialing The ATT command instructs the modem to use tone dialing. This mode will remain in force for all dialing procedures unless an ATP command is issued or the dial string contains a P dial modifier. Tone dialing is the factory-default setting. Vn Result Code Format Options The ATVn command, where n represents 0 or 1, determines if result codes are displayed as numeric (short form) codes or words (long form). Numeric result codes contain only one or two digits and this form could be used, for example, when the modem is controlled by a software terminal emulation program that uses script files. See the list at the beginning of this topic showing result codes in both long and short formats. Type the command ATV or ATV0 to select numeric result codes. The factory default is to display the result codes as words (ATV1). You should issue an ATV1 command either to reset the factory default after a change has been made or to select the long-form (word) result codes. Negotiation progress messages (extended result codes) are those with a numerical value of 40 or more. Four other AT commands, two dial modifiers, and an S-Register are also directly involved in the generation and display of result codes. These are the ATQn, ATVn, ATWn, and ATXn commands, the ATDW and ATD@ dial modifiers, and S-Register S95. Wn Negotiation Progress Message Selection The ATWn command, where n represents 0, 1, or 2, works in conjunction with S-Register S95 to determine how that subset of the result codes - called negotiation progress messages or extended result codes - will be used to report the type of connection, protocol, and other communication techniques that resulted from handshaking and subsequent negotiation. The options available to represent n in the ATWn command are: W0 CONNECT result code reports DTE speed. If S-Register S95=0, disable the display of all extended result codes. W1 CONNECT result code reports DTE speed. If S-Register S95=0, enable the display of CARRIER and PROTOCOL extended result codes only. W2 CONNECT result code reports DCE (modem-to-modem) speed. If S-Register S95=0, disable the display of all extended result codes.

$26 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc &Cn Data Carrier Detect (DCD) The AT&Cn command, where n represents 0 or 1, selects the method by which the modem handles the carrier detect signal. &C0 The carrier detect signal is forced on regardless of the condition of the distant modem's carrier. &C1 The state of the carrier from the remote modem is monitored. The local modem's DCD signal is on when the remote modem's carrier signal is detected, and off when it is not (default). &Dn Data Terminal Ready (DTR) Options The AT&Dn command, where n represents 0-3, controls how the Data Terminal Ready (DTR) signal is used by the modem. &D0 Ignore the DTR signal from the computer and treat it as always on. &D1 Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, switch to command mode, issue an OK result code, and remain connected. &D2 Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, hang up the line and switch to command mode. &D3 Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, hang up, reset the modem and switch to the initialization state. &Fn Load Factory Settings The AT&F command loads factory default parameters from ROM into the active configuration profile, replacing the parameters stored there. This command must be issued by itself. If it is used with another AT command, its function will be ignored. &F0 Recall factory settings as active configuration. &F5 Recall factory settings appropriate for ETC mode as active configuration. This command enables ETC operation. It is automatically set upon detection of a cellular phone. The following options are set with &F5: Local Factory Settings Function MTC Implementation LAPM-only error correction \N4 Transmit level fixed per cellular phone S92 Wait for carrier = 90 sec S7=90 CD loss delay = 10 sec S10=100 Auto FF/FB enabled N/A Start up at 9600bps S40=2$

34 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc Syntax: AT+MS=<carrier>,<automode>,<min_rate>,<max_rate> AT+MS? AT+MS=? +MS? Reports the current settings of subparameters +MS=? Displays range of acceptable values for each subparameter <carrier> Specifies the preferred modulation to be used in originating or answering a connection. The <carrier> subparameter is an unquoted string of characters. If the <carrier> parameter is specified, the other subparameters will revert to factory defaults. If <carrier> is omitted, any unspecified parameters will keep their current values (for example, AT+MS=,0 or AT+MS=,,,2400). Values accepted for <carrier> are the following: B103 Bell 103 (300bps) B212 Bell 212A (1200bps) V21 ITU-T V.21 (300bps) V22 ITU-T V.22 (1200bps) V22B ITU-T V.22bis (2400bps) V23C ITU-T V.23 with constant carrier (1200/75 or 75/1200bps) V32 ITU-T V.32 (4800 or 9600bps) V32B ITU-T V.32bis (4800 - 19200bps) V34 ITU-T V.34 (2400 - 33600bps) K56 Lucent/Rockwell K56flex (32000 - 56000bps). Not applicable under the V.90 standard. To set V.90, see S-Register S109. <automode> Enables or disables negotiation of an alternative <carrier> if the preferred modulation is not available. Values accepted for <automode> are the following: 0 Disabled. Modem will disconnect if it is unable to negotiate a connection with the specified <carrier>. 1 Enabled (default). If the specified <carrier> is unavailable, modem will attempt to negotiate an alternative carrier as appropriate. <min_rate> Specifies the lowest bit rate at which the modem may establish a connection. (This value is fixed at zero for the Xircom modem.) <max_rate> Specifies the highest bit rate at which the modem may establish a connection. For modulations that support only a fixed bit rate (such as V.22bis), <max_rate> has a fixed value to which it defaults. If the default rate or a rate other than zero is specified, the modem will return ERROR. This subparameter accepts the following values: 0, 300, 1200, 2400, 4800, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 31200, 33600bps. If unspecified (set to 0), <max_rate> is determined by the value of <carrier>. If the <carrier> setting is K56, the <max_rate> subparameter should be left at the default value (zero).

Appendix A Modem AT Commands 35 Xircom Inc. Mini PCI User’s Guide Modem S-Registers This section provides the following information:  Introduction to S-Registers  S-Register Reference Introduction to S-Registers The Xircom modem uses memory storage locations, or S-Registers, to hold information controlling its operating environment. Few of these S-Registers require attention from modem users. S-Registers are used in conjunction with Modem AT Commands. To display the value of an S-Register, type ATSn? where n is the number of the S-Register, then press Enter. To modify the value of an S-Register, type ATSn=r where n is the S-Register number and r is the new value or setting, then press Enter. S-Register Reference S0 Ring to Answer After • The contents of register S0 sets the number of rings required before the modem goes off-hook to answer an incoming call (auto answer). The value can range from 0 to 255. ATS0=0 disables the auto-answer function. The default is 0. S1 Ring Counter • This register is read only. The value of S1 increments with each ring. If no rings occur over a six-second interval, the register is cleared. The value of S1 can range from 0 to 255. The default is 0. There may be country-specific limits. S2 AT Escape Character • Register S2 defines the ASCII character used in the Escape sequence. This command is used to return to command mode without losing the connection with a remote modem. Default is S2=43, which is the "+" character. Thus the default Escape sequence is +++. ASCII values 127 and below can be used. To disable this Escape sequence, set S2 equal to a value greater than 127. S3 Command Line Termination Character • This register contains the ASCII value of the command line terminating character (carriage return). The factory default value is ASCII 13 - the carriage return character. You can set register S3 to any value between 0 and 127.

36 Modem AT Commands Appendix A Mini PCI User’s Guide Xircom Inc S4 Response Formatting Character • This register contains the ASCII value of the line feed character. The factory default value is 10. You can set register S4 to any value between 0 and 127. The modem uses a line feed character in command mode when it responds to the computer. S5 Command Line Editing Character • This register contains the ASCII value of the backspace character and is applicable to asynchronous transmissions only. The factory default value is 8. You can set register S5 to any value between 0 and 32, or to 127. The modem will not recognize the backspace character if it is set to a value greater than ASCII 32. S6 Wait Before Blind Dialing • This register determines how long the modem waits after going off-hook before dialing the first digit. The wait must be at least 2 seconds. Register S6 can be set to any value between 2 and 65 seconds. The default is 2 seconds. The value of the W dial modifier will override the value in register S6. This operation, however, may be affected by some ATX options according to country restrictions. There may be country-specific defaults and limits. S7 Connection Completion Time-Out • This register determines the number of seconds the originating modem waits for a carrier signal from the answering modem before hanging up. 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 with the @ dial modifier (in seconds). S7 is not associated with the W dial modifier. Register S7 can be set at from 1 to 255 seconds with a default of 50 seconds. There may be country-specific defaults and limits. S8 Duration of Pause for Comma Dial Modifier • This register determines the number of seconds to pause for each comma (,) in a dial string or command line. The default is 2 seconds, but any value from zero to 65 is acceptable. Defaults and limits are country-specific. S10 Delay Between Lost Carrier/Hang Up • This register specifies the time (in tenths of a second) that the modem waits after carrier loss before hanging up. The default is 20 (2.0 seconds). Register S10 will accept a value ranging from 1 to 254 in tenths of a second (0.1 to 25.4 seconds). There may be country-specific defaults and limits. S11 DTMF Tone Duration • This register determines the "touch tone" dialing speed which is prefixed for each country. The value can range from 50 to 150 milliseconds. The default is 95 milliseconds. The value of register S11 has no effect on pulse dialing. There may be country-specific defaults and limits. S12 Escape Guard Time • This register sets the value (in 20 ms increments) of the required pause after the escape sequence. Range is 0 = 255, default is 50 units of 0.02 seconds each, or one second. S28 V.34 Modulation Enable/Disable • This register enables or disables V.34 modulation. Default setting is 1, valid values are 0 or 1. A value of zero disables V.34 modulation. Any other value in the range enables it.

$Appendix A Modem AT Commands 37 Xircom Inc. Mini PCI User’s Guide S30 Inactivity Timer • The value specified by this register sets how long the modem will wait (in minutes) before disconnecting when no data is sent or received. This function is only applicable in buffer mode. It is set by AT\Tn. Values are 0-255. Default is 0 (disabled). S34 DTE Throughput Limit • This register specifies whether the modem should limit throughput when the DTE is operating at higher speeds (57,600 or 115,200bps) S34=0 Do not limit throughput (default). S34=1 Limit throughput to DTE speed. S35 Data Calling Tone • This register enables or disables a tone of a certain frequency and cadence as specified in V.25 that allows remote data/fax/voice discrimination. It is set by AT-Cn. The frequency is 1300 Hz with a cadence of 0.5 seconds on and 2 seconds off. The default is country-specific. Some countries do not allow data calling tone to be overridden. S35=0 Data calling tone disabled (default). S35=1 Data calling tone enabled. S36 Negotiation Fallback • This register specifies the action to be taken in the event of a negotiation failure when error control is selected. S36=0,2 Hang up S36=1,3 Fall back to an asynchronous connection S36=4,6 Attempt MNP. If MNP fails, hang up. S36=5,7 Attempt MNP. If MNP fails, fall back to an asynchronous connection. S37 Dial Line Rate S37=0 Maximum modem speed (default). S37=1 Reserved. S37=2 1200/75bps. S37=3 300bps. S37=4 Reserved. S37=5 Attempt to connect at 1200bps. S37=6 Attempt to connect at 2400bps. S37=7 Attempt to connect at 4800bps. S37=8 Attempt to connect at 7200bps. S37=9 Attempt to connect at 9600bps.$
