Common Connection Errors / Solutions

Error 602: Port Already Open

There are several possible causes for this error. The steps below should help you pinpoint the cause of the problem and offer a solution.

Possible Solutions
A. Have you checked your modem and phone cord?
B. Have you completely restarted the computer?
C. Another program is accessing your modem
D. Is your modem configured correctly?


A. Have you checked your modem and phone cord?

A bad modem or the phone cord not being plugged in might be the culprit. Make certain that all of your phone line connections going in and out of the modem are tight and secure, then try to connect to Juno again.


B. Have you completely restarted the computer?

Try shutting down and unplugging the computer for 1 minute. Restart the computer and try to connect to Juno again.

Note: If you have an external modem with a separate power cord, once the computer is shut down, unplug the modem power for 1 minute, plug the modem back in, then turn on the modem and restart the computer before attempting to dial again.


C. It is possible that another program has accessed your modem and has not released it.

It is possible that another software program, such as fax software, is holding on to your modem. The modem can not dial another number until the software releases it. To verify whether your modem is being used by another program, please follow the steps below:

Note: The following steps are not applicable to Windows XP users.

Windows 95/98/ME users:

  1. Press and hold the Ctrl, Alt and Delete keys at the same time.
  2. A window will appear, listing all of the programs running on your system.
  1. For every program except Explorer and Systray, click once on each program listed to highlight it and click on the End Task button.

    Note: Each time that you click on the End Task button, you will have to press and hold the Ctrl, Alt and Delete keys to bring the Close Program window back up.

  2. Try your Juno connection again. If this resolves the problem, close Juno and restart your computer. Repeat Steps 1 through 3, clicking End Task for only one program at a time. Each time you use End Task, try your Juno connection again. When you stop receiving the error, the last program you used End Task on is the one creating the conflict.
  3. Once you've found the conflicting program, close it before you logon to Juno. You can contact the manufacturer to see if they have more information about a solution so you can use both Juno and this program at the same time.

After disconnecting from Juno, you can launch the applications that you had closed again by rebooting your computer.

Windows NT Users:

  1. Press and hold the Ctrl, Alt and Delete keys at the same time.
  2. Click on the Task Manager button.
  1. For every program except Explorer and Systray, click once on each program listed to highlight it and click on the End Task button.

    Note: Each time that you click on the End Task button, you will have to press and hold the Ctrl, Alt and Delete keys to bring the Close Program window back up.

  2. Try your Juno connection again. If this resolves the problem, close Juno and restart your computer. Repeat Steps 1 through 3, clicking End Task for only one program at a time. Each time you use End Task, try your Juno connection again. When you stop receiving the error, the last program you used End Task on is the one creating the conflict.
  3. Once you've found the conflicting program, close it before you logon to Juno. You can contact the manufacturer to see if they have more information about a solution so you can use both Juno and this program at the same time.

After disconnecting from Juno, you can launch the applications that you had closed again by restarting your computer.


D. Is your modem configured correctly?

If your modem is not configured correctly, Juno will not function. To verify that your modem configuration is correct, please complete the following steps:

  2. Click on the More Info button.
  1. If your modem is configured correctly, it should display port information regarding your modem. Click OK to exit.

    Note: If you receive an error message, then you will need to configure your modem. This may require that you reinstall your modem drivers and/or configure your modem settings. If this is the case, you should contact your modem or computer manufacturer for information on configuring your modem. If you are on a LAN (Local Area Network), contact your Network Administrator for assistance.

  2. On your desktop, double-click the My Computer icon.
