The pathway between the infrared ports is obstructed, one port is more than 30 degrees (plus or minus 15 degrees off the center line) from the other, or the ports are more than one meter apart.

There is an interrupt request (IRQ) conflict.

There is a baud rate conflict.

There is a conflict with the # bits.

There is a stop byte conflict.

Solution

Install the appropriate software on the second device, start the second device, and start the program on both computers.

Your Compaq computer uses the IrDA communications protocol. Communication between infrared devices must use the same communications protocol. Check the manufacturer's instructions for connecting with infrared devices or try connecting with a device you know to be IrDA-compliant.

Remove the obstruction, align the infrared ports to within 30 degrees, and position computers within 1.5 feet (about 0.5 meter) of each other.

Check for IRQ conflicts in the Device Manager. If two devices have the same IRQ address, reassign one of the devices.

Select the same baud rate for both computers.

Select the same # bits setting for both computers.

Select the same stop byte for both computers.
