350 * SIIG serial cards have an PCI interface chip which also controls

354 * version of serial driver doesn't support differently clocked UART's

356 * high frequency clocking for all UART's on given card. It is safe (I

358 * with other OSes (like M$ DOS).
359 *
360 * SIIG support added by Andrey Panin <pazke@donpac.ru>, 10/1999
361 *

365 * - 20x cards have control registers in standard PCI configuration space.
