COM Port and IRQ Conflicts - General
If you have isolated the problem with IRQs or COM ports, refer to the following sections for resolving IRQ
and COM port conflicts in Windows 95.
When installing a card in an IBM PC compatible computer, it is important to choose settings for the PC
Card which does not conflict with any other cards in the computer.
Choose an Interrupt (IRQ) and a COMx: port for your terminal adapter card, that does not interfere with
any other devices in your computer. Select the Port and Interrupt you want to use, and remember to
update your communications software to the same settings.
The following is a list of some settings other cards in your computer may already be using.
COM Port and IRQ Conflicts - Windows 95
In Windows 95, right-click on My Computer, select Properties from the menu, click on the Device Manager tab,
double-click on Ports, then double-click on the Communications Port your TA is connected to. In the port’s
Properties sheet, click on the Resources tab to see the port’s Input/Output range and Interrupt Request. If
another device is using the same address range or IRQ, it will appear in the Conflicting Device List.
Uncheck “Use Automatic Settings” to change the port’s settings so they do not conflict with the other
device, or select the port the conflicting device is on and change it instead. If you need to open your
computer to change switches or jumpers on the conflicting device, refer to the device’s documentation.
