0327    Default port speeds do not follow Microsoft Standard
0328    Adding extra local printer ports requires reboot to work correctly
0332    DTR flow control causes machine to hang when DTR asserted.
0409    Problems occur when ports are opened before driver is initialised.
0410    No support for SI XIO PCI (z280) boards.
0413    No support fot Jet SI XIO (ISA,EISA,PCI) boards.
0420    IOCTL_SERIAL_PURGE doesn't flush the SI XIO transmit buffer.
