Abstract:

    Oxford Semi 16PCI95X serial port support.

    This is specifically targeted to the 18.432 MHz clock input to the 16PCI95X on 
    the SIIG CyberPro series of PCI serial cards.  Note that support for any 16PCI95X device
    can be easily added (up to standard 16550 baud rates) by changing recognition of
    the device and clock prescaler parameters.
