Serial or Parallel Device Problems
If a system error message indicates a port problem or if equipment connected to a port seems to perform incorrectly or not at all, the source of the
problem can be any of the following:
l A faulty connection between the I/O port and the device
l Incorrect settings for system setup options
l Incorrect settings in the operating system's configuration files
l
A faulty cable between the I/O port and the device
l A faulty device
l Faulty I/O port logic on the system board
l
Conflicting COM port settings
l Lack of drivers
Basic Checks:
l Disconnect the cable from the computer and check the cable connector for bent or broken pins. Check for damaged or frayed cables.
l If the cable is not damaged, make sure that it is firmly connected to the computer.
l Test the electrical outlet. Verify that the device is connected to a working electrical outlet.
l Verify that the device is turned on.
l Check for interference: electrical appliances on the same circuit or operating in close proximity to the computer can cause interference.
If the problem still exists after you complete the basic checks, fill out the Diagnostics Checklist as you perform the following steps:
1. Enter system setup and check the Integrated Devices option settings. Then exit system setup properly to save the information, and reboot
the system.
For a serial device, check the Serial Port options; for a parallel device, check the Parallel Port options. See the device ’s
documentation for additional information on port settings and configuration requirements.
