changing serial port adress

Hi,

I need to change the adress of the serial port. Standard its 0x3F8. I
searched the linux source code for this address and only found
/include/asm-i386/serial.h which contains

#define STD_SERIAL_PORT_DEFNS			\
	/* UART CLK   PORT IRQ     FLAGS        */			\
	{ 0, BASE_BAUD, 0x3F8, 4, STD_COM_FLAGS },	/* ttyS0 */	\
	{ 0, BASE_BAUD, 0x2F8, 3, STD_COM_FLAGS },	/* ttyS1 */	\
	{ 0, BASE_BAUD, 0x3E8, 4, STD_COM_FLAGS },	/* ttyS2 */	\
	{ 0, BASE_BAUD, 0x2E8, 3, STD_COM4_FLAGS },	/* ttyS3 */

i changed it to the new address but i doesn't seem to work.. :(

this time i searched the source codes for STD_SERIAL_PORT_DEFNS but it looks
like it is never used?

someone has any experience with this?

greetz,

Luuk
