software is not running 
on both computers.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 
manufacturers 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 1.5 
feet (about 0.5 meter) of each other.
There is an interrupt 
request (IRQ) conflict.Check for IRQ conflicts in the Device 
Manager. If two devices have the 
same IRQ address, reassign one of 
the devices.
There is a baud rate 
conflict.Select the same baud rate for both 
computers.
There is a conflict with 
the # bits.Select the same # bits setting for 
both computers.
There is a stop byte 
conflict.Select the same stop byte for both 
computers. 
						

							There is a parity 
conflict.Select the same parity setting for 
both computers
Cannot transmit 
data.Direct sunlight, 
fluorescent light, or 
flashing incandescent 
light is close to the 
infrared connections.Remove the interfering light 
source(s).
There is interference 
from other wireless 
devices.Keep remote control units such as 
wireless headphones and other audio 
devices away from the infrared 
connections.
There is a physical 
obstruction in the way.Do not place objects that will 
interfere with a line-of-sight data 
transmission between the two units.
One of the units was 
moved during data 
transmission.Do not move either unit during data 
transmission.
The orientation of the 
units is wrong.Adjust the devices so that they point 
directly at each other.
The distance between 
the units is too great.Verify that devices are not more than 
1.5 feet (0.5 meter) apart.
Infrared port 
doesnt work.Direct sunlight, 
fluorescent light, or 
flashing incandescent 
light is close to the 
infrared connections.Remove the interfering light 
source(s).
There is interference 
from other wireless 
devices.Keep remote control units such as 
wireless headphones and other audio 
devices away from the infrared 
connections.
