3. Check the contents of the start-up files.
See "Installing and Configuring Software" in Chapter 4.
Are the port configuration commands correct?
Yes. Go to step 5.
No. Go to step 4.
4. Change the necessary statements in the start-up files.
If the port problem is confined to a particular application, see the application's
documentation for specific port configuration requirements.
Is the problem resolved?
Yes. You have fixed the problem.
No. Go to step 5.
5. Reboot the system from the diagnostics diskette, and run the Serial/Infrared
Ports test group and/or the Parallel Ports test group in the Dell Diagnostics.
See Chapter 5, "Running the Dell Diagnostics."
The Serial/Infrared Ports test group and the Parallel Ports test group test the
basic functions of the system board's I/O port logic. Also, if a parallel printer is
connected to the parallel port, the Parallel Ports test group tests the communi-
cations link between the system board's I/O port logic and the printer.
Did the tests run successfully?
Yes. Go to step 6.
No. See Chapter 11, "Getting Help," for instructions on obtaining technical
assistance.
6. If the problem persists, go to "Troubleshooting a Parallel Printer" or "Trouble-
shooting a Serial I/O Device" found later in this chapter, depending on which
device appears to be malfunctioning.
If the procedure in the preceding subsection, "Troubleshooting the Basic I/O Func-
tions," indicates that the problem is with a parallel printer, follow these steps:
1. Turn off the parallel printer and computer.
2. Swap the parallel printer interface cable with a known working cable.
3. Turn on the parallel printer and computer.
