Test the electrical outlet. Verify that the device is connected to a

the computer.

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

group in the

I/O port logic. If a printer is connected to the parallel port, the
Parallel
Ports
device group tests the communication link between the system
board's I/O port logic and the printer.
Do the tests complete successfully?
Yes.
