We Welcome Your Suggestions We've made every effort to provide you with useful, accurate information. If you have any comments or suggestions about these materials, please let us know. Voicemail: Email: (847) 933-5200 sysdocs@usr.com Chapter 1 The Courier The Courier V.Everything External Modem makes any computer or terminal with an EIA/RS-232 serial port (or a Macintosh serial port) capable of exchanging data with modems or fax machines over standard, analog telephone lines at speeds of up to 33.6 Kbps. Using the Courier The most common uses of the Courier modem are for accessing the Internet or online services, accessing corporate networks remotely, calling bulletin board systems (BBSs), and for sending or receiving facsimiles or files. Using the Courier always requires some kind of communications software. The software required differs depending on what you're trying to do. Accessing the Internet To access the Internet, you need to set up an account with an Internet service provider in your area. Often, Internet service providers supply you with the software you'll need. In other cases, support for Internet access is built in to your computer's operating system, as is the case with Windows 95. The software needed to access the Internet is called a TCP/IP protocol stack. Your TCP/IP protocol stack must provide a dialing application that is capable of sending data over a serial line using the Point-to-Point protocol (PPP) or the Serial Line Internet Protocol (SLIP). The Courier 1-1 Calling Online Services Each online service, such as America Online or CompuServe, provides its own customized communications software package. A couple of these packages are included with the Courier. These packages do the dialing and guide you through the steps of registration. Accessing Corporate Networks Remotely Dialing in to a remote network requires remote access software. When you dial in to a network, the software makes your remote computer appear to the network as locally attached. You can then use your network just as you would if you were there: send mail, print files, and access LAN drives. A remote access package is included with the Courier. Calling Bulletin Board Systems (BBSs) Calling a BBS requires communications software that does terminal emulation. The software should also support common, standard file transfer protocols, such as YMODEM and ZMODEM. A communications software package is included with the Courier. Sending Facsimiles or Files Most communications software packages support file transfers and many support fax operations. You can use fax-capable software to call fax machines or other fax modems and send facsimiles. 1-2 Courier V.Everything External Modem: Getting Started Courier Controls, Displays, and Connectors These figures show the controls, displays, and connectors on the Courier and indicate where to find more information about each.

The Courier is in fax mode. Error correction not active/not retransmitting data/not in fax mode. Features 33.6 Kbps Connectivity The Courier contains software that enables 31.2 and 33.6 Kbps connection rates, as well as improves throughput at lower speeds. While line conditions may not always allow for 33.6 Kbps connections, the new software makes it more likely that your Courier will achieve and maintain 28.8 Kbps connections. It can add up to 4800 bps to the average V.34 connection rate. Selective Reject Selective Reject is an optional part of the ITU V.42 (LAPM) specification. This feature improves performance on noisy lines by reducing the amount of overhead incurred when the protocol must resend data due to errors. When selective reject is active, only the frame that contained the error is resent, instead of the frame plus all of the following unacknowledged frames. You can disable selective reject by changing a setting in S-Register 51 (see Appendix A, Alphabetic Command Summary, in the Courier Modems Command Reference manual). Attaining Speeds Above 28.8 Kbps V.34 connections at 21.6, 24.0, and 26.4 Kbps are common. To get connections of 28.8, 31.2, and 33.6 Kbps, line quality must be pristine end-to-end. In addition, 31.2 and 33.6 Kbps connection rates are possible only when the device to which you are The Courier 1-5 connecting also runs software that supports speeds above 28.8 Kbps. If you are curious about the role that line quality plays in attaining and maintaining high speed connections, and want to learn what you can do to improve connections, request the following document from our Fax on Demand service: Phone Line Quality and High Speed Connections. The Fax on Demand number is (800) 762-6163. V.Everything The Courier provides full support of the V.34 standard, V.Fast Class, V.32 terbo, and many other modulation schemes, spanning the range of speeds between 33.6 Kbps and 300 bps. We call this unique combination of abilities V.Everything. See the Compatibility section in Appendix B, Technical Specifications, for details. Flash ROM Upgradability Courier modems are software-upgradable using XMODEM file transfers, allowing you quick, easy access to updates of the Courier's technology. See Chapter 17, Upgrading the Courier's Software, in the Courier Modems Command Reference manual. Dial Security The Courier's dial security functionality is part of its operating software, which allows you to control access at a modem-tomodem level instead of using software that runs on the host computer. With Dial Security, you can prevent unauthorized access to a system through the use of password prompting and dialback. Refer to Chapter 9, Dial Security, in the Courier Modems Command Reference manual. 1-6 Courier V.Everything External Modem: Getting Started Remote Configuration and Diagnostics You can remotely configure and test the Courier. If you are a network administrator supporting remote users, this feature can save you time and money. Refer to Chapter 8, Remote Access, in the Courier Modems Command Reference manual. Adaptive Speed Leveling (ASL) Couriers monitor line conditions while connected, and fall back to the next lower speed--for example, 19.2K, then 16.8K in V.32terbo mode--if conditions are poor. Couriers also detect improved line conditions and shift upward to the next higher speed. Transmit and receive channels adapt independently, each detecting and adjusting to line conditions. Calls to and from Modems and Fax Machines When used with fax-capable communications software, the Courier auto-detects and responds to calls from modems and Group III fax machines, using EIA-standard Class 1 or 2.0 fax software. Testing ITU-T V.54 loopback testing is available. The Courier can perform analog, digital, and remote digital loopback tests. See Chapter 15, Testing, in the Courier Modems Command Reference manual. Caller ID Support The Courier can interpret and display caller ID information. See the Caller ID section in Chapter 3, Dialing, Answering, and Hanging Up, in the Courier Modems Command Reference manual. Distinctive Ring Support The Courier can be set to recognize and respond to any of four distinctive ring patterns. See the Distinctive Ring section in Chapter 3, Dialing, Answering, and Hanging Up, in the Courier Modems Command Reference manual. The Courier 1-7 Carrier Loss Redial If you enable the carrier loss redial feature, the Courier will automatically redial the last number it dialed if carrier is lost (for example, if there is trouble on the line or if the remote modem hangs up). This feature is useful for dialed-line connections that operate unattended. See Chapter 3, Dialing, Answering, and Hanging Up, in the Courier Modems Command Reference manual. Plug and Play Support The software for the external Courier has been developed to support Plug and Play (as defined by the Plug and Play External COM Device Specification, Version 1.00). When you connect the Courier to a computer that uses a Plug and Play operating system, such as Windows 95, the computer will automatically detect and configure itself to the support the Courier. Synchronous Support The Courier can connect to synchronous serial ports to allow access to mini- and mainframe computers. See Chapter 12, Dedicated/Leased Line and Synchronous Applications, in the Courier Modems Command Reference. Dedicated- and Leased-Line Support The Courier does not need to be connected to the public switched telephone network. You can connect a standard telephone cable between the Courier and another modem and make connections without even dialing. You can also connect the Courier to a line that you lease from the telephone company. See Chapter 12, Dedicated/Leased Line and Synchronous Applications, in the Courier Modems Command Reference. 1-8 Courier V.Everything External Modem: Getting Started Chapter 2 Installing the Courier What You Need A Computer or Terminal with a Serial Port The Courier is compatible with any computer or terminal that provides a serial port with an EIA-232 interface. See Appendix A, The Serial Port, for details. For top performance, your serial port must support speeds of 115.2 Kbps. For IBM-compatible PCs, make sure your computer has a 16C550 UART. Check your computer's documentation for details. An Analog Telephone Line The Courier requires a standard, analog telephone line. Do not connect the Courier to a digital telephone line. Digital lines are commonly used in office buildings and hotels. If you are unsure whether your line is analog or digital, ask a network administrator or your local telephone company. Communications Software You must configure and run a communications software package in order to make the Courier work. The Courier is shipped with a DOS/Windows communications software package. Installing the Courier 2-1 A Serial Cable Because there are a variety of connector types that different computers require, a serial cable is not provided with the Courier. See the next section, Choosing a Serial Cable, for guidelines. Choosing a Serial Cable 1 Check the back of your computer for a serial port. Serial ports may be labeled with the word COM or RS-232 or with symbols such as IOIOI, , or . Refer to your computer's documentation to be sure. DB-25, Male DB-9, Male 8-pin Mini-DIN (Macintosh) Figure 2-1. Typical Serial Ports. 2 Depending on what kind of serial port is on your computer, obtain a serial cable with a connector that will fit (either a female DB-25, female DB-9, or a male 8-pin Macintosh serial connector). The Courier's end of the serial cable must be a male DB-25 connector. For a Macintosh, you need a hardware handshaking cable. NOTE: If you plan to connect the Courier to a mainframe computer or use the Courier to dial in to a mainframe computer, refer to Chapter 12, Synchronous Applications, in the Courier Modems Command Reference manual. 2-2 Courier V.Everything External Modem: Getting Started Package Contents The Courier Power adapter Phone cable Quick reference card Customer support services card DOS/ Windows communications software package A Command Reference manual and this Getting Started manual Figure 2-2.

Once you're sure that your computer can communicate with the Courier, you're ready to start making or taking calls! The methods of verifying communication with a modem vary depending on the operating system your computer uses. Windows 95 Windows 3.x Windows NT RAS DOS OS/2 Mac OS UNIX/AIX/Linux Mainframe OSs This chapter provides advice about how to get many popular operating systems to communicate with the Courier. The last section, Testing the Courier, explains how to verify that your Courier and software are working together correctly. Windows 95 The first time you start Windows 95 after you've installed the Courier, Windows 95 will auto-detect the Courier. Make sure the Courier is powered on when you start Windows 95. Windows 95 has built-in support for Couriers, but since the Courier has been updated since the release of Windows 95, you need to supply Windows 95 with an updated INF file so it can properly identify your Courier. The latest INF file is always available from our BBS and our ftp site. Communicating with the Courier 3-1 Getting the INF File 1 Power on your computer with the modem installed. As Windows 95 loads, it presents a New Hardware Found panel. Select Standard Modem. Start a communications software package (such as HyperTerminal, which is included with Windows 95) and dial the U.S. Robotics BBS at (847) 982-5092. Go to File directories, then 5) U.S. Robotics Courier. Download the MDMUSRCR.INF file. 2 Or, ftp://ftp.usr.com/SYS/PCB/dl05 and get MDMUSRCR.INF. Installing the INF File 1 Go to an MS-DOS Prompt: Microsoft® Windows 95 ©Copyright Microsoft Corp 1981-1995 c:\WINDOWS> 2 Change to the directory in which you put the INF file, for example, the TEMP directory. C:\WINDOWS>cd\temp Windows responds: C:\TEMP> 3 Enter the following command: C:\TEMP>copy mdmusrcr.inf \windows\inf Windows responds: 1 file(s) copied Be aware that the \inf directory is hidden, and even though it may not appear, it is there. 3-2 Courier V.Everything External Modem: Getting Started Making Windows 95 Auto-Detect Your Courier 1 2 3 Click Start | Settings | Control Panel and then double-click Modems.

You can use Windows Terminal to test the Courier or you can install the communications software package that is included in the package with the Courier. Windows Terminal is in the Accessories group by default. Because Terminal only supports speeds up to 19200 bps, you will probably want to use a third-party communications software package, such as Quick Link II instead. For Quick Link II, see the section, Testing the Courier, on page 3-14. For other Windows software packages, see Chapter 5, Setups for Common Windows Software Packages. For instructions about how to set up your Windows communications software package, call our fax-on-demand service (at 800-762-6163 or 847-676-1598) or our BBS (at 847-9825092). Request document 10000 for a list of our technical support documents. Communicating with the Courier 3-5 DOS Because there is no communications software built in to DOS, you must install and run a third-party communications software package in order to operate the Courier. The Quick Link II diskette, which is included in the package with the Courier, contains a DOS version of the software as well as a Windows version. You must choose the COM port to which the Courier is attached in whatever communications software package you are using. For instructions about how to set up your DOS communications software package, call our fax-on-demand service (at 800-7626163 or 847-676-1598) or our BBS (at 847-982-5092). Request document 10000 for a list of our technical support documents. OS/2 To get the best performance, you should replace the standard OS/2 serial port drivers COM.SYS and VCOM.SYS with SIO.SYS and VSIO.SYS. You can get these enhanced drivers from our BBS at 847-982-5092. Check file area 18, OS/2 Support, Utilities, etc for SIO153.ZIP. For help with OS/2 Warp installations, download the file WARPIN.ZIP from BBS file area 18, OS/2 Support, Utilities, etc. For instructions about how to set up your OS/2 communications software package, call our fax-on-demand service (at 800-7626163 or 847-676-1598) or our BBS (at 847-982-5092). Request document 10000 for a list of our technical support documents. 3-6 Courier V.Everything External Modem: Getting Started Mac OS Be sure you're using a hardware handshaking cable to connect the Courier to the Macintosh. Also, if you won't be using AppleTalk Remote Access (ARA), then set AppleTalk to Inactive (in Chooser). Otherwise ARA may interfere with your communcations software. As a general rule, set DIP switches 1, 3, 5, and 8 ON, and use AT&F1 as your modem initialization string. For instructions about how to set up your Macintosh communications software package, call our fax-on-demand service (at 800-762-6163 or 847-676-1598) and request document 10000 for a list of available documents. Or, call our Macintosh BBS (at 847-676-1598). Windows NT As a Client If you want only to dial out using the Courier, Windows NT works very much like Windows 3.x. Windows NT ships with a built-in Terminal program that can support speeds of up to 115.2 Kbps. Additionally, Windows NT includes a Remote Access Dialer, but it is not installed by default. You can install Quick Link II in Windows NT but you may experience problems with fax operations. As a Server Here's how to set up Windows NT Remote Access Service (RAS) to recognize the Courier. First, you must install RAS, which is included with Windows NT but is not installed by default. Communicating with the Courier 3-7 Start Windows Terminal to verify that NT can communicate with the Courier. Select the COM port to which the Courier is connected. You should be able to send AT and get an OK response. From the Control Panel, double-click Network. The Network Settings window appears. Scroll down the list of Installed Network Software and select Remote Access Service. Click Configure... The Remote Access Setup windows appears. Click Add... 3-8 Courier V.Everything External Modem: Getting Started Select the port to which the Courier is connected. When you click OK, Remote Access setup asks you if you would like it to try to detect the modem connected to the port. Click Cancel to select the Courier from a list. Select US Robotics Courier V.34, and then click OK and exit from Network setup. When you're prompted to restart NT, click Don't Restart Now. Then, from Program Manager, click File | Shutdown. When NT shuts down, power your computer off and then on again. Now RAS knows about the serial port and the Courier that is attached. Next, you need to set up user accounts and access privileges; those tasks are beyond the scope of this manual. Communicating with the Courier 3-9 UNIX/Linux/AIX If the Courier will be answering, set DIP switch 3 OFF; 4 and 8 ON. Linux has a built-in communications software package called minicom. By default, minicom is located in the usr/bin directory. For instructions about how to set up your UNIX, Linux, or AIX communications software package, call our fax-on-demand service (at 800-762-6163 or 847-676-1598) or our BBS (at 847-9825092). Request document 10000 for a list of our technical support documents. Mainframe OSs Refer to Chapter 12, Synchronous Applications, in the Courier Modems Command Reference manual. 3-10 Courier V.Everything External Modem: Getting Started Testing the Courier Use any communications software package for this test. Quick Link II Fax is used as an example. Quick Link II Fax 1 2 Install and then start Quick Link. Click Setup | Line Settings... Make the following settings. If you are using a computer with a serial port that cannot support high speeds, choose 19200. Then click OK. 3 4 5 Click Setup | Modem Setup... Select the Comm. Port to which the Courier is attached. Click OK. In the terminal window, type AT . The Courier should respond OK. Dial the U.S. Robotics BBS at (847) 982-5092.

Voice/Data Switch HS AA CD NS RD SD DTR MR RTS CTS SYNC ARQ/ FAX VOICE/DATA COURIER V.EVERYTHING with V.34 Volume Control Volume Control The volume control is located under the right front of the Courier. Slide the control toward the front of the Courier to increase the volume. Slide the control toward the back of the Courier to decrease the volume. Use the ATMn command to control when the speaker sounds. M1 is the default. Mn Control when the speaker sounds. M0 M1 M2 M3 The speaker is always off. The speaker is on until the call is negotiated. The speaker is always on. The speaker turns on after the last digit is dialed and stays on until the call is negotiated. Example: ATM1 . Other Features 4-1 The Voice/Data Switch The Voice/Data switch allows you to alternate voice and data over the same connection. You call the remote user by telephone, then you each press the Voice/Data switch on the Courier. After you're finished sending and receiving files, press the Voice/Data switch to return to voice. You can accomplish the same function by sending AT commands, and you can also assign a different function to the Voice/Data switch if you don't plan to use it for alternating voice and data. Changing back to voice after the modems connect requires that both modems have handset exclusion. Handset exclusion means that when the modem is using the phone line, the modem automatically disconnects the phone (handset). If you keep the handset off hook, once you hang up the modem, the handset takes over the phone line and you can use voice communications again. If the remote user does not have handset exclusion, you may not be able to switch back to voice mode successfully once you have switched to Data mode. If the remote user does not have a Voice/Data switch, he or she can follow the instructions for using the appropriate AT command. See the next section for details. Using the Voice/Data SwitchS32=1, S32=2 Either user can start the call, but you need to decide up front which modem will originate and which will answer. 1 Send the modem that will originate ATS32=1 Sending ATS32=1 tells the Courier to go on line and send ATD when you press the Voice/Data switch. 2 Send the modem that will answer ATS32=2 4-2 Courier V.Everything External Modem: Getting Started Sending ATS32=2 tells the Courier to go on line and send ATA when you press the Voice/Data switch. NOTE: If you've stored a command string (using &ZC=s), the Courier will default to S32=9, which executes the stored command string when you push the Voice/Data switch. 3 Call the remote user (make a voice call) or have them call you. You must the phone that is attached to the Courier's PHONE port. When you're ready for the modems to connect, press the Voice/Data switch of the "originating" modem (the one that set S32=1). The handset goes dead. Do not hang up the phone. Immediately afterward, press the Voice/Data switch of the "answering" modem (the one that set S32=2). The modems go through the normal negotiation process. If the answering modem has handset exclusion, the answering user should not hang up the phone either. If the remote modem doesn't have handset exclusion, you can try to switch back to voice later. Or, you both can hang up your phones as soon as the modems go off hook. 4 Using CommandsATD, ATA If your Voice/Data switch is set for a function other than Voice/Data operations and you don't wish to change it, use AT commands. 1 Make a voice call to the remote user (or have the remote user call you). You must both use telephones that are connected to the PHONE port of your modems. Other Features 4-3 2 If you are to originate the connection, type the following command: ATD NOTE: Be sure the modem is not set to X2, X4, X6 or X7, or it will return the NO DIAL TONE result code and hang up. 3 4 The remote user should type the answer command: ATA If the remote modem also has handset exclusion, leave both phones off hook in case you wish to switch back again to voice after your data transfer. If the remote modem doesn't have handset exclusion, switching back to voice may not be successful. If you don't want to switch back to voice later, hang up both phones as soon as the modems go off hook. Changing the Function of the Voice/Data Switch Use Register S32 to set the voice/data switch for the function you desire. The default is S32=1pressing the switch forces the modem off hook in Originate mode. Holding the switch in when you power on the modem causes it to perform a power-on self-test. NOTE: Some of the applications listed below require preconfiguration. Review the Chapter (from Table 4-1) in the Courier Modems Command Reference before assigning the Voice/Data switch function. 4-4 Courier V.Everything External Modem: Getting Started Table 4-1.

If a command string has been stored (&ZC=s), the Courier sends the stored command string when you push the Voice/Data switch. If no command string is stored, the Courier still reports that S32=9, but actually behaves as if it is set to S32=1, Originate mode. You can program the voice/data switch to execute a stored command string when pressed. The following example assigns a command string that displays the link diagnostics screen when you press the voice/data switch. AT&ZC=I6 Set the voice/data switch function to execute stored command string by setting Register S32 to 9 with the following command: ATS32=9 Note that you can reset the voice/data switch at any time to one of the other available functions. Additionally, you can overwrite the stored command string with a new one at any time. Once you've stored your command string and set Register S32, press the Voice/Data switch whenever you want the Courier to send the command string. Other Features 4-5 Getting Information About Calls Here are the commands that provide detailed information about your current settings and current and last calls. To get call-in-progress data and current settings while you are on line, set DIP switch 9 OFF and then send ATZ (or power the Courier off and then on). Alternatively, you can send ATS14.0=0 , but be aware that the DIP switch setting will override your setting at power on or reset (even if you add &W to write the command to NVRAM). Once you've set DIP switch 9 or sent ATS14.0=0 , you can type the following command to get to online command mode, and the Courier will not hang up: +++ To return on line, type: ATO Current Settings Current settings Data or fax mode ATI4 AT+FCLASS? 0=Data 1=Class 1 fax 2.0=Class 2.0 fax Call in Progress Speed Duration Modulation Error control protocol Compression type Data or fax mode ATI6 -- Speed ATI6 -- Current Call ATI11 -- Modulation ATI6 -- Protocol ATI6 -- Compression AT+FCLASS? 0=Data 1=Class 1 fax 2.0=Class 2.0 fax 4-6 Courier V.Everything External Modem: Getting Started Last Call Last-dialed number Disconnect reason Speed Duration Modulation Error control protocol Compression type ATI4 -- Last Dialed # ATI6 -- Disconnect Reason is ATI6 -- Speed ATI6 -- Last Call ATI11 -- Modulation ATI6 -- Protocol ATI6 -- Compression MI/MIC Operations Couriers are shipped with MI/MIC disabled, that is, for normal use. Mode Indicate/Mode Indicate Common (MI/MIC) closure is required for some applications where existing hardware, such as a PBX, does the dialing. For these applications, the Courier must power up in Originate mode. Then the Courier goes on line and accepts data when it connects with the number dialed by the system equipment. Once you've set Register S34, have the system force the modem off hook by closing the MI/MIC leads in the phone line connector. Setting the MI/MIC Jumpers 1 2 3 4 5 6 Send ATS34.5=1&W . Power off the Courier and disconnect all of its cables. Turn the Courier upside down. Remove the two square vinyl feet and put them aside. Remove the two Phillips screws located in the wells beneath the vinyl feet. Pry off the plastic volume slide-switch cover. Raise the back end of the case bottom and lift it away.

Location of the MI/MIC Jumpers. 9 Set the jumpers as shown: From J4 J6 To J4 J6 cables. 10 Replace the modem and reconnect the CAUTION: When you power on the modem there will be potentially hazardous voltage, particularly near the phone jacks. Do not touch the board when the power is on. 11 Power on the modem. Check to see that the Off Hook (OH) status light goes on. If you dialed a number, listen for an answer tone from the remote modem. Then drop the DTR signal. The modem should go on hook and the OH status light should go off. 4-8 Courier V.Everything External Modem: Getting Started 12 When you are sure the equipment is working correctly, reassemble the Courier. Troubleshooting If the Courier does not respond to MI/MIC closure, or if the Courier fails to go back on hook when the computer or terminal drops the Data Terminal Ready (DTR) signal, your phone equipment probably reverses MI/MIC polarity. You can solve this problem by reversing the modem's MI/MIC wiring. Do this by resetting the two jumpers on the printed circuit board. Follow the steps from the previous section. This time, set the jumpers as follows: From J4 J6 To J4 J6 If you still have difficulty, there may be a problem with the phone cable or with your hardware.
