Serial port problems

Use this information to troubleshoot the serial port and devices attached to the serial port.
Symptom: Serial port cannot be accessed.
Actions:
• Ensure that the serial cable is securely connected to the serial port on the computer and to the serial

electrical outlet.
• If the serial device has its own On/Off switch, ensure that it is in the On position.
• If the serial device has an Online switch, ensure that it is in the Online position.
• If the serial device is a printer, ensure 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.
• Ensure 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 Lenovo Solution Center program. If you need technical
assistance, see "Lenovo Support Web site" on page 34.
