Cannot communicate with another computer

The required software is not running on both computers.

One computer does not have an IrDA- compliant infrared port.

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

Communication between infrared devices must use the same protocol.

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 1.5 feet (about 0.5 meter) apart.

There is an interrupt request (IRQ) conflict.

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

1.5feet (about 0.5 meter) of each other.

Check for IRQ conflicts in the Device Manager on one or both computers. If the Device Manager indicates an IRQ conflict, reassign the IRQ number for one of the conflicting devices.

There is a baud rate conflict.

There is a conflict with the # bits.

There is a stop bit conflict.

There is a parity conflict.

Select the same baud rate for both computers.

Select the same “# bits” setting for both computers.

Select the same stop bit for both computers.

Select the same parity setting for both computers.
