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.
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.

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.
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.
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.
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.
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.

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.
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 Install and then start Quick Link. 2 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 Click Setup | Modem Setup… Select the Comm. Port to which the Courier is attached. Click OK. 4 In the terminal window, type AT .
NOTE: If you need to dial 9 to get an outside line, dial as in this example: ATDT9,18479825092 . If you want to disable call waiting for this call, in most areas, dial *70 before you dial the phone number, for example, ATDT*70,18479825092 . The following screens are what you should see when you dial the BBS.
Chapter 4 Other Features This chapter explains how to use features specific to the Courier V.Everything External Modem, including the volume control, the Voice/Data switch, and MI/MIC operations. 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.
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.
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.
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 The remote user should type the answer command: ATA 4 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.
Table 4-1. Voice/Data Switch Commands.
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).
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.
7 Remove the modem (printed circuit board), carefully easing the voice/data switch out of its opening in the front panel. 8 Locate jumpers J4 and J6. J4 J6 MI/MIC Jumpers Figure 4-1. Location of the MI/MIC Jumpers. 9 Set the jumpers as shown: To From J4 J6 10 Replace the modem and reconnect the J4 J6 cables. 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.
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.
