• Make sure that the serial cable is securely connected to the serial port on the computer and to the serial
device. If the serial device has its own power cord, make sure that it is attached to a properly grounded
electrical outlet.
• If the serial device has its own On/Off switch, make sure that it is in the On position.
• If the serial device has an Online switch, make sure that it is in the Online position.
• If the serial device is a printer, make sure that paper is loaded correctly.
• Verify that any software supplied with the serial device is correctly installed. Refer to the documentation
for the serial-device option.
• Make sure that the serial-port adapter, if you added one, is properly installed and firmly seated.
If these actions do not correct the problem, run the diagnostic programs (see “Diagnostic programs” on
page 108 for instructions). If you need technical assistance, see Chapter 11 “Getting information, help, and
service” on page 111.
Software problems
Select your symptom from the following list:
• “When using a sort feature, dates do not sort in the correct order” on page 107
• “Software does not work as expected” on page 107
When using a sort feature, dates do not sort in the correct order
Symptom: When using a sort feature, dates do not sort in the correct order.
Action: Some software developed before the year 2000 used only the last two digits of a year to sort
dates, always assuming the first two digits were 19. Consequently, these programs sort dates out of order.
Check with your software manufacturer to see if any updates are available. Many software manufacturers
make updates available from the World Wide Web.
Software does not work as expected
Symptom: Software does not work as expected.
Actions:
• Most software programs have built-in help systems that provide instructions for most tasks. If you are
having difficulty performing a specific task within a software program, refer to the help system for that
program. Help systems are typically accessible from a menu or button in the program, and frequently
from the F1 key.
• If you are having difficulty with the Windows operating system or one of its components, refer to the
Windows help system. It is accessible from the Windows Start menu.
• To determine if problems are caused by newly installed software, verify that:
– Your computer has the minimum memory requirements needed to use the software. See the
information supplied with the software to verify memory requirements. (If you just installed an adapter
or memory, you might have a memory-address conflict.)
– The software is designed to operate on your computer.
– Other software works on your computer.
– The software you are using works correctly on another computer.
• If you received any error messages while using the software program, see the printed documentation
supplied with the software or the help system for that software for a description of the messages and
solutions to the problem.
