In the phone book settings, under security, select Accept any authentication including clear text. Make sure only the necessary network protocols are selected In the Connect to window, after you click Dial, there should be no domain set. This is only for logging into NT domains. s s s s s Other Operating Systems 1-13 s Make sure that the TCP/IP settings are correct. This is a general setup for your Courier V.Everything modem using Windows NT. If you are having problems connecting to youISP, configuring Dial-Up Networking, or receiving RAS errors, please contact Microsoft Technical support. Other Operating Systems This sections explains how to configure your modem for: s s s s Windows 3.x MS-DOS OS/2 UNIX, Linux, or AIX If You Are Using Windows 3. Windows 3.x comes with a built-in communications software package, Windows Terminal. You can use Windows Terminal to test your modem or you can install the communications software package that is included on the Connections CD-ROM. Because Windows Terminal only supports speeds up to 19200 bps, it is recommended that you use a third-party communications software package. If You Are Using MS-DOS Because there is no communications software built in to MS-DOS, yo must install and run a third-party communications software package t operate your modem. You must choose the COM port to which your modem is attached in whatever communications software package you are using. If You Are Using UNIX, Linux, or AI For instructions about how to set up your UNIX®, Linux, or AIX communications software package, see the software's installation procedure. To set your Courier V.Everything modem to answer incoming calls, set DIP switch 3 OFF; set 4 and 8 ON. 1-14 CHAPTER 1: CONNECTING TO YOUR ISP 2 USING THE AT COMMAND SET This chapter includes information about s s s Basic AT commands Using S-Registers Understanding bit-mapped S-Registers Overview You can use AT commands to change your modem settings at any time. To send AT commands to your modem, you need to put your communications software inTerminal Mode. In terminal mode, what you type is sent directly to the modem. General rules for using AT commands You must follow some general guidelines to send AT commands to your modem: s Type AT before each command and press Enter after each command. Leave zeroes off the end of AT commands. A missing numeric parameter is assumed to be a zero. For example, ATE is equivalent t ATE0 Create compound commands of up to 56 characters between AT and Enter. See the following example. The exceptions are A/, A> and +++, which require neither AT nor Enter. s s 2-2 CHAPTER 2: USING THE AT COMMAND SET AT&K3X2DT5551234 AT &K3 X2 DT Attention; a command follows. Disable MNP5 data compression; use only V.42 bis compression. Use the X2 result code subset. Dial the following number using tone dialing. Hyphens and parentheses add to the count of 56 characters but spaces do not. Basic AT commands The command AT informs the modem that a command is coming. AT must precede all commands except A/, A> and +++. To configure your modem to Re-execute the last-issued command. Repeat the last-issued command until canceled by pressing any key. Command A/ A> Example: Sending ATD5551234 will make the modem dial 555 1234. Now, if you send A/ the modem will dial 555 1234 again. Using S-Registers S-Registers are addresses of places in memory where various timin parameters, redefinitions of selected ASCII characters, and other configuration settings are stored. Initially, the S-Register settings for each of the NVRAM templates are the same. You can overwrite an S-Register's stored value. See the default values listed in Appendix A, S-Registers, for a complete listing of the initial settings. Using S-Registers 2-3 Displaying S-Register settings You can display S-Registers in a variety of ways. See the table below for more information. To display Contents of ONE S-Register S-Register settings in the NVRAM templates S-Register settings in RAM (the current configuration) Command ATSr?, where r is the register's number ATI5 ATI4 Example: Sending ATS0?, displays the contents or setting for S-Register 0. When using the commands ATI4 and ATI5, S-Register settings appear as a table seven columns wide, each entry of the form, "Smm=nnn" where mm is a register number between 0 and 70 and nnn is a decimal value between 0 and 255. Setting an S-Register You can configure each S-Register setting manually. CAUTION: If you do not write an S-Register setting with &W, the setting will be retained only until the next reset or power off. To change Command ATSr=n Settings for a register in the current configuratio Example: Sending ATS0=2, changes the setting for S-Register 0 to 2. This setting will cause the Courier V.Everything modem to answer, in Auto Answer Mode, on the second ring. In the command ATSr=n, r is the register's number and n is a decimal value from 0-255 (unless otherwise indicated) that specifies the setting. 2-4 CHAPTER 2: USING THE AT COMMAND SET Getting a list of S-Registers To display Command ATS$ A list of S-Registers In order to issue this command, you must be in Terminal Mode. See Appendix A, S-Registers for a complete list of S-Registers. Understanding bit-mapped S-Registers A bit-mapped S-Register uses one number to describe a collection of settings. Bit-mapping allows us to pack a lot of information in a small space. Bit-mapped registers are in the form of Sr.b=n, where r is the bit-mapped register; .b is the bit; n is 0 (off) or 1 (on) See Appendix A, S-Registers to see how bits are mapped into decimal values and for information about setting bit-mapped S-Registers. 3 UPGRADING YOUR MODEM This chapter contains information about: s s s s s Checking your modem's software version Getting new operating software Sending new software to the modem If your modem doesn't respond Remote flash Checking Your Courier V.Everything Modem's Software Version Issuing the ATI7 command produces the following information to appear on your terminal screen ati7 3Com Courier V.Everything Configuration Profile...

Follow these steps to force the new software to the modem. 1 Power your modem on. 2 Start your communications software package. Set your port speed to 57,600 bps, type AT and press Enter. If the CourierV.Everything modem reports .bootmodem., it is corrupt. Issue the ATXMODEM command and repeat the flash process found on the previous page. 3 Power your modem off 4 Set the DIP switches to their previous settings. 5 Power your modem on. Remote Flash In order to upgrade the modem located at a remote site, you need to ensure that the remote modem is enabled for remote access (see Chapter 9). Call the remote modem from your local site and follow the steps outlined in that chapter. 3-4 CHAPTER 3: UPGRADING YOUR MODEM 4 MODES OF OPERATION This chapter contains information about s s s Command and Online Modes Controlling Local Echo Data and Fax Modes Command and Online Modes If you want to Control the modem using AT commands Depending on how DIP switch 9 is set, sending the escape code (+++) will return the Courier V.Everything modem to Command Mode or hang up. To be able to change operating modes without losing connections, set DIP switch 9 down. Your modem set to revert to Command Mode when the Escape Code (+++) is used. Your modem to Disconnect when the Escape Code (+++) is used Return to your connection after an Online Command Mode session. Send the modem commands while you are on line with another device Set the modem to Command Mode Use this command +++ (Escape Code) DIP switch 9 DOWN DIP switch 9 UP Online Mode ATO0 Online Command Mode +++ (Escape Code) DO NOT type AT before +++ or Enter after the command 4-2 CHAPTER 4: MODES OF OPERATION Entering Online Command Mod When the modem is in Online Mode, the only command it recognises is an escape code, or +++. Revert to Command Mode without losing connections by using settin DIP switch 9 down or sendin ATS14.0=0 to the modem before establishing your connection. 6 Wait one second after sending the last item of data. 7 Type +++ 8 Wait for OK to appear before typing any data. You can change the characters used to revert to Command Mode or the wait time by resetting Register S2 or S12. For more information about resetting these S-Registers, see Appendix A, S-Registers. Returning to Online Mode There are two ways to return online using the ATOn command. . If you want to Return online Return online and retrain Command ATO0 ATO1 Example: Sending ATO1, will allow you to resynchronise if you experienced errors during a non-ARQ data transfer. Controlling Local Echo Command-Mod Local Echo There are two local echo settings, one for Command Mode and one for Online Mode. You can configure your modem to display the commands you type on screen by using the ATEn command . If you want the commands you type to NOT appear on screen (Command Mode echo OFF) Appear on your screen (Command Mode echo ON) Command ATE0 ATE1 Although you cannot see the command when you set ATE0, the modem is receiving them. Data and Fax Modes 4-3 Online-Mode Local Echo To configure your modem to display a copy of data that is bein transmitted on your screen you can use the ATFn command. As the modem transmits data to a remote system The modem sends a copy of the data to the screen. Online local echo ON (half duplex). Command ATF0 No copy of the data is displayed on screen. Online echo OFF ATF1 (default) (full duplex). Example: Sendin display window. ATF0 will allow you to see what you are typing in the You may see the term duplex used in place of online local echoing, although the term is not technically accurate. Data and Fax Modes Once you are in Command Mode, you can initialise the modem in Data or Fax mode. Fax operations require facsimile-compatible communications software that can send or receive Group III faxes. Follow the instructions in your fax software manual. The modems default operating mode is Data Mode. Most fax software automatically switches the device to Fax mode when you run the program, and resets the device to Data mode when you exit the progra . If you want the modem prepared to Make calls to and receive calls from other modems Make calls to and receive calls from analogue facsimile devices, such as fax modems and fax machines Mode Data Mode Fax Mode Command AT+FCLASS=0 AT+FCLASS=1 (Class 1 Fax Mode) or AT+FCLASS=2.0 (Class 2.0 Fax Mode) Example: Sending AT+FCLASS=1, allows you to receive faxes from fax machines. 4-4 CHAPTER 4: MODES OF OPERATION Class 1 and Class 2.0 Fax Modes refer to standards set by the Electronic Industries Association/Telecommunications Industry Association. Class 1 Fax Mode is the minimal standard for computer-faxmodem interface. Class 2.0 Fax Mode refers to the extended computer-faxmodem interface. If you are not sure whether your modem is in Data or Fax mode, use the AT+FCLASS? command . If the modem returns a value of 0 1 2.0 This indicates Data Mode Class 1 Fax Mode Class 2.0 Fax Mode. Whenever the modem is reset using the ATZ command or by turning the power off and then on, it will reset to Data Mode 5 DIALING, ANSWERING, AND HANGING UP This chapter explains how to use basic AT commands for: s s s s s s s Dialing Carrier loss redial Answering calls Making International calls Call detection Caller ID functions Distinctive Ring support Dialing You can use your modem to dial the specified telephone number an execute dial options by using the following commands. Dial options For your modem to Dial the specified phone number and execute dial options (DO NOT use spaces or dashes). Tone dial. Pulse dial. Pause for the length of time specified by S-Register 8. The default is 2 seconds. Pause for 125 milliseconds. Wait for a second dial tone before continuing dialing. This command only works only if the X3 (or higher) command has been issued (see Chapter 7, Controlling Result Code Displays and Appendix D, Result Code Meanings and Sets). If the modem is set to X2 or lower, it interprets the W as a two-second pause, unless it detects a second dial tone within two seconds. Command ATD phone number ATDT ATDP ATD, (Comma) ATD/ (Slash) ATDW 5-2 CHAPTER 5: DIALING, ANSWERING, AND HANGING UP For your modem to Wait for an answer (with X3 or higher). Some online services answer the phone and return a tape-recorded request for information before processing transactions. Use the AT@ command to tell the modem to detect at least one ring, wait for five seconds of silence at the other end of the call, and then continue. To use the AT@ command, set the modem to X3, X4 or X7. If set X2 or lower, the modem will return an ERROR message when it encounters the @ character. If set to X5 or X6, the modem hangs up when it detects a voice answer. Return to Command mode after dialing. Dial the letters that follow (in an alphabetical phone number). Command ATD@ ATD; (Semicolon) ATD" If you are including another command after the phone number, use closing quotation marks before the additional command. IMPORTANT: With the exception of the above Dial options, your modem will ignore any commands issued after the D in the same command string. Call a device that can only originate calls. It forces the modem to dial out at the answer frequency or Reverse frequencies. You can put the R either before or after the number. Display different sets of result codes. See Chapter 7, Controlling Result Code Displays and Appendix D, Result Code Meanings and Sets. Dial the last-dialed number. Use ATDL instead of using A/ if you wish to send the modem non-Dial commands before dialing again. Display the last-dialed number. Dial the number stored in nonvolatile random access memory at position n, where n = 0-9. See Chapter 6, Working with Memory, for instructions about saving phone numbers to memory. Digits 0 through 9, * and # are accepted. Stop dialing or stop repeating. Reissue the last command (Don't type AT or press ). Type any key A/ ATDR ATX2D..... X7D ATDL ATDL? ATSn Carrier Loss Redial 5-3 For your modem to Dial a number, wait 60 seconds for a connection, and then hang up. Wait two seconds, then redial. Make a maximum of 10 attempts. To stop the repeating, press any key during the pause between dial attempts. If you press any key while the modem is dialing, that dial attempt is canceled but the cycle will continue Dial the last-dialed number and repeat it just as the > command does. Also can be used to repeat any command. Command > A> Carrier Loss Redial You can set the Courier V.Everything modem to redial the last-dialed number after it loses carrier (carrier is the signal maintained between two modems while they are on line). This feature is useful for dialed-lin connections that operate unattended. For your modem to Disable carrier loss redial Enable carrier loss redial Wait n seconds between losing the connection and redialing. This command also defines the interval (in seconds) between dialing attempts if the first attempt is not successful. Command ATS69.1=0 ATS69.1=1 ATS44=n Example: Sending ATS44=20 sets a 20-second interval between losing the connection and redialing. Answering Call Your modem can be configured to answer calls. By default, your Courier V.Everything modem will not automatically answers calls 5-4 CHAPTER 5: DIALING, ANSWERING, AND HANGING UP Force Answer Mode For your modem to Go through the answer sequence when it hasn't received an incoming call Or Manually answer a call Command ATA Auto Answer You can set your modem to Auto Answer using the ATS0 command For all Courier V.Everything modems except the PC card version, DIP switch 5 overrides the ATS0=n setting. . For your modem to Receive calls unattended (Auto answer enabled) Remember to set your communications software to save incoming messages and/or files. Command ATS0=1 (this instructs the modem to answer on the first ring) NOT receive calls unattended (Auto answer disabled) ATS0=0 Example: Sending ATS0=0 will not allow your modem to receive calls when you are not present. See the S-Register summary in Appendix A, S-Registers for more information about instructing the modem to answer after more than 1 ring. When your modem senses a call coming in, it sends the result code RING to your computer, goes off hook, and negotiates for a connection. If there is no response within 60 seconds, the Courier V.Everything mode hangs up For more information about adjusting the 60-second wait-for-connectio time using S-Register 7, see Appendix A, S-Registers. When a call is disconnected, the Courier V.Everything modem hangs up and returns the NO CARRIER result code. If S0=0, Auto Answer is disabled. To determine if Auto Answer is NOT disabled send the comman ATI4 and be sure that S0=1-255. Making International calls 5-5 Hanging up If you want to end a connection with a remote device do the following: 1 Enter Online Command Mode by typing +++ 2 Wait 1 second 3 Type ATH Making International calls Handshaking options You can use the AT n and AT&Gn commands for making analogue international calls above 1200 bps. The ATBn command controls the handshake options. . If you want your modem To answer all V.34-type calls, as well as calls from abroad, use ITU-T (formerly CCITT) answer sequence. NOT to answer V.34-type calls. Use Bell answer tone. This setting selects HST modulation. Command ATB0 (Default) ATB1 Example: Sending ATB1, will allow your modem to use Bell answer tone (selecting HST modulation). Guard ton The AT&Gn command only applies to analogue international calls at 240 or 1200 bps. To set your modem for No guard tone 550-Hz guard tone 1800-Hz guard tone Command AT&G0 (Default) AT&G1 AT&G2 Required in these countries United States and Canada Some European countries The U.K. and some Commonwealth countries If you set &G2 you must also sen ATB0 to the modem. This setting allows the Courier V.Everything modem to answer all calls from overseas. 5-6 CHAPTER 5: DIALING, ANSWERING, AND HANGING UP Call Detectio Call Detection allows the modem to recognise whether an incoming call is analogue data or fax. Call Detection is an optional Service Class 2.0 feature and is also implemented by 3Com for Fax Class 1 applications. Caller ID Functions Caller ID is a service provided by local telephone companies. When you subscribe to Caller ID, your phone company begins providing you real-time information about incoming calls. The Caller ID signal includes the date and time of the call, the phone number of the calling device, and, optionally, the name of the calling party. The signal is sent between the first and second rings and must be decoded and displayed by a device connected to your phone line. The Courier V.Everything modem has the ability to decode and display the Caller ID information. Service Types You can subscribe to Basic or Extended Caller ID service. Basic service offers you the date and time of the call and the calling party's telephone number. Extended service provides the billing name associated with the calling party's telephone number in addition to the Basic service information The information the Courier V.Everything modem actually receives depends on the service type to which you've subscribed, the information that the calling party's telephone company provides, and whether the equipment in between supports Caller ID. At minimum, you will always receive the date and time that a call arrived. If a call arrives without a Caller ID signal, the modem will send OUT OF AREA in place of the phone number and name. If the Caller ID information has been blocked by the user at the other end, the Courier V.Everything modem will send PRIVATE in place of the phone number and name. Applications of Caller ID Technolog You can use Caller ID to screen calls, keep a record of calls, or prevent unauthorised access to your network. Third-party database an telephony applications such as security, call logging, and black-listing applications exploit the Caller ID information provided by the Courier V.Everything modem. Caller ID Functions 5-7 How the Courier V.Everything Modem Handles Caller ID When the modem receives the Caller ID signal, it stores the information i memory. You can access the information at any time by sendin ATI15 to the modem. ati15 3Com Courier V.Everything CID Status... 80 1E 01 08 31 30 31 35 32 30 33 38 02 0A 37 30 38 35 35 35 30 30 30 31 07 0C 55 2E 53 2E 52 4F 42 4F 54 49 43 53 22 DATE = 1015 TIME = 2038 NMBR = 8475550001 NAME = 3Com OK Using the #CID command (described below), you can have the Courier V.Everything modem send the information to your computer between the first and second RING messages. The Caller ID information is displayed only once. RING DATE = 1015 TIME = 2038 NMBR = 8475550001 NAME = 3Com RING The information remains in memory until either you reset the modem or until it receives another valid Caller ID signal. To be sure that the Courier V.Everything modem receives the Caller ID signal when auto-answer is enabled, set S0=2 or higher or make sure your communications software is set to answer on 2 or more rings. 5-8 CHAPTER 5: DIALING, ANSWERING, AND HANGING UP Presentation Formats The Courier V.Everything modem sends the Caller ID information to your computer formatted or unformatted. Formatted presentation is a translation of the Caller ID signal into ASCII text. Unformatted presentation is a hexadecimal representation of the Caller ID signal An Example of Formatted Caller ID presentation: RING DATE = 1015 TIME = 2038 NMBR = 8475550001 NAME = 3Com RING An Example of Unformatted Caller ID presentation RING 801E01083130313532303338020A37303835353530303031070C552E532E 524F424F5449435322 RING Commands The following table describes the AT#CID=n settings.

(800)521-2673 U.K. Information: Technical and Regulatory Standards Evolution Unit PP 11.1, 207 Old Street London EC1V 9NR United Kingdom Helpline: 0800 318601 Distinctive Ring Support Distinctive ring is a service provided by local telephone companies that permits the assignment of multiple phone numbers to one line. Each phone number is associated with a different ring pattern, and devices that recognise distinctive ring, like the Courier V.Everything modem, can be set to answer only on certain incoming ring patterns. For example, a fax machine, answering machine, telephone, and modem could all share the same line. Each device would have its own phone number and respond only to calls intended for that number. 5-10 CHAPTER 5: DIALING, ANSWERING, AND HANGING UP There are four ring patterns in common use: Ring A B C D Description 1.2 to 2.0 seconds on, 4.0 seconds off. 0.8 second on, 0.4 second off, 0.8 second on, 4.0 seconds off. 0.4 second on, 0.2 second off, 0.4 second on, 0.2 second off, 0.8 second on, 4.0 seconds off. 0.3 second on, 0.2 second off, 1.0 second on, 0.2 second off, 0.3 second on, 4.0 seconds off. Commands For your modem to Enable recognition of Ring A Disable recognition of Ring A Enable recognition of Ring B Disable recognition of Ring B Enable recognition of Ring C Disable recognition of Ring C Enable recognition of Ring D Disable recognition of Ring D Command ATS70.0=1 ATS70.0=0 ATS70.1=1 ATS70.1=0 ATS70.2=1 ATS70.2=0 ATS70.3=1 ATS70.3=0 Example: Sending ATS70.0=1.3=1 to your modem enables the recognition of ring types A and D only. When a call comes in with a ring type A or D, the Courier V.Everything modem will send the result code RING A or RING D, respectively. The Courier V.Everything modem will ignore other ring types. If S70 is set to 0 (the default) the Courier V.Everything modem detects ring types A and B, sending the result code RING for either ring type. This function is identical to that of other 3Com modems that do not support distinctive ring. If only one ring type is enabled, the Courier V.Everything modem will recognise only the enabled ring type and ignore all others. It will send the result code RING only when it detects the ring type that's enabled.
