The SETODI is a self-configuring
driver that automatically detects the
correct LPT port, interrupt line, and
unidirectional/bidirectional mode
to be used. If you have a special
configuration, you may need to
override this automatic selection by
using the NET.CFG file. Otherwise,
you should skip this section.

The NET.CFG file is an auxiliary
file used by the ODI drivers. It
includes configuration information
about the network adapters in your
workstation. If you do not use any of
the special options listed in this
section, you do not need to edit
NET.CFG.

the semicolon out of the
corresponding line.
The pocket adapter driver section
in the NET.CFG file must start with
the line LINK DRIVER SETODI,
which identifies the driver to which
the driver options apply. The next
line is optional and must start with
an empty space, such as a true space
or a tab.
the line LINK DRIVER SETODI,
which identifies the driver to which
the driver options apply. The next
line is optional and must start with
an empty space, such as a true space
or a tab.
The options are as follows:
• POLLING—A PC may use either
IRQ-7 or IRQ-5 for handling the
parallel port communications. If
you need to work without
interrupts (usually only with test
evaluations), delete the
semicolon in this line. This will
force the driver to operate in a
polled mode without using
hardware interrupts.

• UNIDIR—Whenever the
SETODI driver is loaded into
memory, it tests the parallel port
to determine whether it can be
operated in the faster
bidirectional mode. The Adapter
is then configured according to
the test results. However, when
you use a long extension cable
or a low-quality parallel port, the
bidirectional mode may not
operate reliably, even if the test
passes. In this case, you should
force the unidirectional mode by
deleting the semicolon in this
line.

Adapter is auto-configuring,
automatically detecting the
correct port to be used. To
specify the exact parallel port
with which the SETODI driver is
to work, delete the semicolon in
this line and specify the port
number (1 to 4) in place of the
n.
