OL97: Stack Fault ErrMsg in Kernel32.dll Using AutoDialer

• Microsoft Outlook 97

SYMPTOMS

When you use the AutoDialer to make a call to a Microsoft Outlook 97 Contact, you may receive the following error message:

   Outlook caused a stack fault in module KERNEL32.DLL at 0137:bff72408

CAUSE

This error message may occur when you hang up before completing the call, and then try to make another call before the Call Status dialog box is closed.

WORKAROUND

To work around this problem, wait until the Call Status dialog is closed before initiating another call.

On some modems, selecting the FIFO buffers option will increase the response speed of the modem, and reduce the likelihood of the error. To select the FIFO buffers, choose the appropriate method from the following.

5. Click to select "Use FIFO buffers (requires 16550 compatible UART)."

6. Click OK twice, and then click Close.

In Windows NT

If you are running Windows NT, follow these steps:

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

2. In control Panel, double-click the Ports icon.

3. Click to select the modem port and then click Settings.

4. Click Advanced.
