Notes:
• The above installation procedure installs a module type driver. If you can not install
the driver successfully, you may need to use a kernel type driver. You will need to
enter the Build directory and run Install again. In kernel type drivers, you may need
to have the full source le for the Linux system to be re-compiled.
• Each serial card needs an open IRQ for Plug and Play function.
