Avoiding Interrupt Assignment Conflicts

Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the

documentation for the default IRQ line setting for each installed device. Then consult

Table 3

to configure the device for one of the

available IRQ lines.

NOTES: Installed devices cannot share the same COM port address. The default address of your computer's serial port is

COM1.

To view IRQ line assignments in the Microsoft

®

Windows

®

95 and Windows 98 operating systems, click the

Start

button,

point to

Settings

, and click

Control Panel

. Double-click the

System

icon. Select the

Device Manager

tab, and then double-

click

Computer

.
