Device Manager Ports List for AT Serial Board Correctly Installed

Verify the Hardware Resources

For every port of the newly installed serial interface, double-click on the

name of the serial port in the Device Manager. Then, click on the

Resources tab. If the resources were assigned correctly, the Resources

page shows which resources are assigned to your serial ports.

If Windows Me/9x did not assign any resources to the port, the Resources

page shows only a Set Configuration Manually button. Click on the Set

Configuration Manually button and try to assign conflict-free resources

to your serial hardware. For instructions, refer to the Selecting

Conflict-Free Resources section of Appendix D, Troubleshooting and

Common Questions. You may have to free an interrupt request level so that

one can be assigned to your serial hardware. For instructions, refer to the

Freeing an Interrupt Request Level section in Appendix D,

Troubleshooting and Common Questions.

When you have finished verifying the hardware resources, proceed to the

next section.
