Troubleshooting the Infrared Port

This section provides a procedure for troubleshooting the
computer's infrared port. Make a copy of the Diagnostics
Checklist found in Chapter 5, and fill it out as you com-
plete the following procedure.
NOTE: Before beginning this procedure, check the infra-
red settings in Windows 95. Select the Start button, and
point to Settings and then to Control Panel. Double-click
the Infrared icon.
1. Check the setting for the Infrared Data Port
option in the System Setup program. Is the setting
correct?
For information on the System Setup program, see
Chapter 2, "Customizing System Features." Is the
Infrared Data Port option set correctly for the exter-
nal device with which you are communicating? You
may need to check the documentation that accompa-
nied the device to determine the proper setting.
Yes. Go to step 3.
No. Go to step 2.
2. Change the Infrared Data Port option to the
appropriate setting, and then reboot the system.
Is the problem resolved?
Yes. The problem is resolved.
No. Go to step 3.
3. Insert the Dell Diagnostics Diskette into drive A,
reboot the computer, and run the Serial/Infrared
Ports test group in the Dell Diagnostics. (See Chap-
ter 4, "Running the Dell Diagnostics.") Do the tests
complete successfully?
The Serial/Infrared Ports test group checks the basic
functions of the computer's infrared logic.
Yes. The infrared ports are functioning properly.
There may be a problem with the infrared applica-
tion program or with the external device. Check the
documentation that came with the application pro-
gram and the external device.
No. Call Dell for technical assistance. (See Chapter 5,
"Getting Help," for instructions.)
