Solving Infrared Problems
Problem Possible Cause Solution
Cannot communicate
with another
computer
The appropriate
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
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
1.5 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.
