Configuring the polled mode and quick close settings for a PCI host card
RIO allows some basic configuration of host cards as follows.
Polled mode RIO allows you to run the PCI card in polled mode i.e. without using interrupts. This facility is
useful when the normal interrupt levels used by RIO are not available or you have a larger
number of host cards than available interrupt levels.
Quick close facility When a RIO port is closed in software, the close will not complete until all data in the buffers
has been transmitted. This maintains data integrity. A quick close facility is available which
allows the system to close a port immediately when requested to do. This facility is useful
when you want to reduce the time taken to close a collection of ports, but final data integrity
is not important.
To use either of these facilities proceed as follows:
1. Click the Start button > Control Panel
The control panel window is now displayed.
2. In the Control Panel window, click on the System icon.
The System Properties tabbed window is now displayed.
Note
If you enable the quick close option, any data buffered in the driver will
be lost.
