If you are unable to make a successful connection, or if you experience data loss or garbled characters during your connection, check the list of troubleshooting procedures before calling Multi-Tech.

  • Page 53: The Modem Does Not Respond To Commands

    5 Troubleshooting The Modem Does Not Respond to Commands Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”) Make sure you are issuing the modem commands from the data communications program, either manually in terminal mode or automatically by configuring the software.

    5 Troubleshooting To change a port address or IRQ in Windows 3.1x, double-click the Control Panel icon, then the Ports icon. Click on the port you want to change, click Settings, click Advanced, and select the new port address and/or interrupt. If you wish to use COM3 or COM4, note that COM3 shares an IRQ with COM1, as does COM4 with COM2, so you should change their IRQs to unused ones, if possible.

  • Page 55: The Modem Disconnects While Online

    5 Troubleshooting installation, plug a phone into your modem’s phone wall jack and listen for a dial tone. If you hear a dial tone, your modem might be installed behind a corporate phone system (PBX) with an internal dial tone that sounds different from the normal dial tone.

  • Page 56: The Modem Cannot Connect When Answering

    5 Troubleshooting Check for loose connections between the modem and the computer, the phone jack, and AC power. You might have had a poor connection because of line conditions or the problem might have originated on the other end of the line. Try again. If you were online with a BBS or an online service like CompuServe, it might have hung up on you because of lack of activity on your part or because you exceeded your time limit for the day.

  • Page 57: Data Is Being Lost

    5 Troubleshooting Data Is Being Lost If you are using data compression and a high speed serial port, set the serial port baud rate to four times the data rate. Your UART might not be reliable at serial port speeds over 9600 bps or 19,200 bps.

    E Upgrading the Modem Appendix E: Upgrading the Modem Introduction Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added.
