Dial-Up Networking Errors
Error 630
When you try to start Dial-Up Networking, you receive the following error message:
Error 630: The computer is not receiving a response from the modem. Check that the modem is plugged in, and if necessary, turn the modem off, and then turn it back on.
This error message can occur if the modem is using a newly detected serial port installed by Windows 98 hardware detection. If this is the case, change the properties of the Dial-Up Networking connection to use the new modem settings.
Programs run at StartUp from the StartUp folder can also cause this error message.
To temporarily disable programs in the StartUp folder, follow these steps:
1.Click Start > Run and in the Open: box, type msconfig, then press OK
2.In Msconfig click the Startup tab. For programs that may control your modem, click the program's check box to clear it. If you are not sure whether or not a specific program should be disabled, click to clear all of the check boxes except for the following check boxes:
ScanRegistry
TaskMonitor
SystemTray
LoadPowerProfile (is loaded twice normally)
If you receive this error on Windows 98 Second Edition, and you have an 3Com (USR) USB modem, you have 2 options and 1 workaround, until 3Com releases new drivers:
Option 1: Revert back to Windows 98 (Gold) (uninstall Windows 98 Second Edition)
Option 2: Install the modem as a serial device Work-around:
1.Select Start > Settings > Control Panel
2.Double-click Modems, and then verify that your modem is listed on the General tab
3.Click Diagnostics, select the COM port to which your modem is attached, and then click More Info
Your modem should now be accessible to other Windows applications for the remainder of your Windows session.
Note: This will need to be done each time windows has been restarted.
