Serial Port Problems Action

The number of serial ports displayed is less than the number of serial ports installed.

Verify that:

1.Each port is assigned a unique address.

2.The serial-port adapter, if you installed one, is seated properly.

If the items above are correct, have the system serviced.

Printer Problems Action

The printer does not work.

Verify that:

1.The printer is turned on and is online.

2.The printer signal cable is connected to the correct serial or parallel-port on the system. (For the location of the serial or parallel port, see the User's Reference.)

Note: Non-IBM printer cables might cause unpredictable problems.

3.You have assigned the printer port correctly in your operating system or application program.

4.You have assigned the printer port correctly using the Setup program.

If the items above are correct and the printer still does not work, run the tests described in the manual that comes with your printer. If the tests show the printer is OK, have the system serviced.
