Epson Equity 286 PLUS - Manual (Page 50)

If you have installed three additional parallel ports and you
do not want to use the built-in port, select Disable.
Note
Be sure to also set any jumpers on the card(s) you install to
indicate how you want the port to be recognized (LPTl,
LPT2, or LPT3).
Setting the Serial Interface
The built-in serial port in your computer is set to act as the
primary port (COMl). If you install an option card that
provides an additional serial interface, that port automatically
becomes a secondary port (COM2). However, if you want the
secondary port to act as the primary, you need to select
COM2
for the built-in port.
If you install a card (or cards) that provide two additional serial
ports and you want them to act as the primary and secondary
ports, you need to select
Disab1e for the built-in port.
Note
Be sure to also set any jumper (s) on the card(s) you install to
indicate whether you want the port(s) to be primary or
secondary.
Setting the Disk Drive Controllers
If you are using the standard drives that came with your
computer’ the hard disk drive controller (HDC) and diskette
drive controller (FDC) should be set to
Enab1e .
However, if you install an option card that provides a controller
for a diskette drive or hard disk drive, you need to disable the
built-in controller.
