Setup parameters 5-9
Devices and I/O Ports
From the Setup main menu, select the
Devices and I/O
Ports
option to view or change port configuration settings.
The Devices and I/O Ports menu appears. This menu lets
you configure serial and parallel ports.
Also included in this menu are items for enabling or disabling
the onboard controller chipsets.
Onboard communication ports
Serial Port
Your computer comes with a 9-pin serial port. This
parameter is set to Enabled which is the default serial port
setting. The default setting base address is 2F8. The default
IRQ is 3.
If you install a modem or a serial port adapter card, use this
parameter to make any changes to the serial port address
which may be needed to avoid conflicts with additional
hardware. If you change the serial port address, you might
also need to make changes in the software that uses the
serial port. For instructions on changing your software, see
the user’s guide or online documentation that came with the
software.
Parallel port
Your computer comes with one parallel port. This parameter
is set to Enabled which is the default parallel port setting.
The default base address is 378h. The default IRQ is 7.
If you install an adapter card with a parallel port, use this
menu to make sure that each parallel port has a different
address. If you change parallel port addresses in this menu,
you might also need to make changes in the software that
uses the parallel port. For instructions on changing your
software, see the user’s guide or online information that
came with the software.
Operation mode
As long as the parallel port setting is not disabled, this item
allows you to choose an operation mode for the parallel port.
You can select either the Standard mode or one of the
extended modes (Bidirectional, EPP, or ECP) for a parallel
port operation mode. The extended modes increase the
efficiency of your parallel port; however, these modes use
recent technology and are only supported by newer
hardware (such as some printer models). The available
modes are:
Standard
. This mode allows for one-way operation at a
normal speed, and is the default setting.
Bidirectional.
This mode allows for two-way operation
at a normal speed.
EPP.
This mode allows for bidirectional parallel port
operation at a maximum speed.
