CAUSE

This behavior can occur if there is line noise or a resource conflict between the WinModem and another device in your computer.


RESOLUTION

To work around this behavior, follow the steps in the appropriate section below:


Line Noise

If line noise is preventing consistent connections to your ISP, follow these steps:

  1. Click Start, point to Settings, and then click Control Panel.


  2. Double-click Modems.


  3. On the General tab, click your modem, and then click Properties.


  4. On the Connection tab, click Advanced.


  5. In the Extra Settings box, type one of the following modem initialization strings:

    
          s32=66
    
          s32=34 


  6. Click OK, click OK again, and then click Close.


  7. Test to see if the behavior is resolved. If the behavior is not resolved, repeat steps 1-6, using the other modem initialization string in step 5.
