  • Page 20: A Note About Irqs And Conflicts

    cally modify your AUTOEXEC.BAT and SYSTEM.INI files. We strongly recommend that you answer Yes to these prompts; otherwise, you will need to run the SETPORT utility each time you use your modem. If unsuccessful, the software checks more IRQs until it finds one that works.
  • Page 21 In the unusual event that PORTWIZ configures your faxmodem to use a COM port/IRQ combination that con- flicts with other hardware, either the faxmodem or the other hardware won’t work properly. If that happens, you can run PORTWIZ by itself to try other COM port/IRQ combinations. SETPORT copies PORTWIZ into the root directory (usually C:\) the first time you run it.

  • Page 28 ever, if you need to enter AT commands you must do so from the software’s terminal mode. 56K Faxmodem Owner’s Manual...

  • Page 29: Returning To The Factory Settings

    To use AT commands in terminal mode 1. Start your data communications program. 2. Change to terminal mode (also called command, local, direct, or dumb mode). 3. Type in the AT command you need and press Enter. When you finish, you can return to the data communications program’s standard user interface.

  • Page 30: Chapter 3 Problems And Solutions

    Chapter 3 Problems and Solutions If your modem is not working, please read this chapter and the communications software documentation care- fully. For installation problems, see Chapter 1, Installation. This chapter covers four categories: general trouble- shooting, echo troubleshooting, dial troubleshooting, and on-line troubleshooting.

  • Page 31: General Troubleshooting

    For help with this problem… page… You receive bursts of errors occasionally, but otherwise data quality is good. Random errors occur in transmitted data. Data is missing. Data appears garbled on the screen. The modem works fine when you are not using data compression, but the compression features are inoperative.

  • Page 32: No Response Appears After Executing A

    The modem takes too long to hang up at the Problem: end of a call. Solution: Your modem may not be receiving the required initialization string, which should include the &C1 setting, from your software. In your software, make sure you have selected your modem.

  • Page 33: You Encounter Other Communications Problems

    Be sure your modem is in terminal mode and not in data mode when you type the command. You receive an ERROR response when trying Problem: to execute a command. Check whether you typed the command Solution: correctly. Check whether the command is a valid one. Be sure your command line contains fewer than 40 characters.

  • Page 34: Echo Troubleshooting

    For example, if you want the volume low and the software uses the initialization string AT &F change it to AT &F L1. Echo Troubleshooting Each character you type appears twice or no Problem: characters appear at all during data mode. Make sure that your software is in full-duplex Solution: mode when you make a call.

  • Page 35: On-Line Troubleshooting

    Make sure your modem has hung up from the previous call. Select Hang Up in your software; or change to terminal mode, wait one second, type and press Enter to hang up the modem. On-line Troubleshooting The modem can connect to some modems, Problem: but not to others.
  • Page 36 NOTE 1: You may find it necessary or helpful to include S95=44 in your initialization string. This enables the responses CARRIER (telephone line speed) and PROTOCOL, as well as CONNECT (faxmodem-to-computer speed). NOTE 2: Some software allows these commands to be added to the list of dial prefixes.
  • Page 37 AT S0=1 Auto-answer Your modem disconnects while Problem: communicating with a remote system. The remote system has hung up. Solution: The telephone line disrupted your call. If your telephone service includes Call Waiting, turn it off if possible before making modem calls. Ask your telephone company if you can temporarily disable Call Waiting by pressing *70, or another code.
  • Page 38 Random errors occur or data is missing in Problem: transmitted data. Solution: Use the MNP or V.42 protocol if the remote modem supports one of these protocols. See the table on page 36 for more information. Select a lower baud rate in your communications software and place the call again.
  • Page 39 To get maximum data throughput, you can use a computer-to-modem speed of 230,400 bps (if your COM port can support this speed); set this for each entry in the dialing directory. Be aware that many files downloaded from bulle- tin boards have already been compressed. In general, your modem will not be able to further compress such files.
