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. With kernel type
drivers, you may need to have the full source file for the Linux system and the source
file must be located in the /usr/src/linux directory. If your source file is in a different
location, you must move it or link it to the “usr/src/linux” directory.
• Each serial card needs an open IRQ for Plug and Play function.
