Chapter 4 – Troubleshooting Chapter 4 – Troubleshooting Your MultiModemZDX modem was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss or garbled characters during your connection, it is possible that the modem is defective. However, it is more likely that the source of your problem lies elsewhere. The following symptoms are typical of problems you may encounter: • None of the LEDs light when the modem is on.
Chapter 4 – Troubleshooting • • • • • • • Your communication program settings might not match the physical port the modem is connected to. The serial cable might be plugged into the wrong connector—check your computer documentation to make sure. Or you might have selected a COM port in the program other than the one the modem is physically connected to—compare the settings in the program to the physical connection.
Chapter 4 – Troubleshooting • If the modem reports NO CARRIER, the phone was answered at the other end, but no connection was made. You might have dialed a wrong number, and a person answered instead of a computer, or you might have dialed the correct number but the other computer or software was turned off or faulty. Check the number and try again, or try calling another system to make sure your modem is working. Also, try calling the number on your telephone.
Chapter 4 – Troubleshooting There Are Garbage Characters on the Monitor • Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication software. • 4 You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call again; you might get a better connection the next time.
