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

The other computer does not have an IrDA- compliant infrared port. 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.

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.

Remove the obstruction, align the infrared ports to within 30 degrees, and position computers within

1.5feet (about 0.5 meter) of each other.
