Epson 386SX Setting the Serial and Parallel Interfaces

Setting the Serial and Parallel Interfaces

The serial and parallel interfaces in your computer are set up to act as the primary ports. If these are the only ports you are using in your computer, you can skip this section.

If you install an option card with its own serial or parallel port, however, you may want to designate the built-in port as secondary and the additional port as primary. The Setup program lets you choose which port is primary and which is secondary so there is no conflict between the built-in port and the additional port. Here are some examples:

D If you install an option card with a port pre-set as primary by the manufacturer, you must designate it as the primary port and make the computer’s built-in port the secondary port.

0If you install an option card or peripheral with a port not pre-set, you must designate it as the secondary port and the built-in port as the primary port.

Cl	If you install two option cards with ports, designate one as
	the primary port and the other as the secondary port and
	disable the built-in port.
Follow these steps to change your built-in serial and parallel
interface settings:
1.	At the main Setup menu, highlight Serial/
	Parallel. The current settings for each port appear:		.
	Serial	Primary
	Parallel	Primary
