CREATIVE PORTFIX 82C710
version 1.00
Creative Labs, Inc.
15 June 1992
Description:
------------
PORTFIX was written to enable the serial and parallel ports on
motherboards with the Chip & Technologies 82C710 Universal Peripheral
Controller and an installed Sound Blaster board.
This program turns on the serial port (3F8h) and the parallel port
(378h) if it is not already provided on an external card. If they
are already on an external board then the on-board ports will remain
unavailable.
Installation:
-------------
Using your favorite editor, place PORTFIX in the AUTOEXEC.BAT file
before any programs which use the serial port. This includes mouse
drivers, fossil drivers, and communication programs.
