4-port 386

[Rocky Wu]

I'm trying to set up 4 serial ports with 2 KW-524H cards.
I got no response from COM3 and COM4, but COM1 and COM2 are
fine. (524H has 2 serial ports, one parallel and one game port.) 
Does anyone know what the problem is OR whether
it is allowed to have two IO cards on the system?
I changed the dip switches according to the manual.
The following is my setup.

	COM1	IRQ 4	3f8-3ff	
	COM2	IRQ 3	2f8-2ff
	COM3	IRQ 5	3e8-3ef
	COM4	IRQ 9	2e8-2ef
	I also disabled the parallel on both cards.

My unix configuration is:

/etc/conf/init.d/mdevice:
	asy  Iocrwi  iHct  asy  0  3  1  4  -1

/etc/conf/init.d/asy

	00:23:respawn:/etc/getty tty00 9600
	01:23:respawn:/etc/getty tty01 9600
	02:23:respawn:/etc/getty tty02 9600
	03:23:respawn:/etc/getty tty03 9600

/etc/conf/node.d/asy

	asy  tty00  c  0
	asy  tty01  c  1
	asy  tty02  c  2
	asy  tty03  c  3

/etc/conf/sdevice.d/asy

	asy  Y  1  7  1  4  3f8  3ff  0  0
	asy  Y  1  7  1  3  2f8  2ff  0  0
	asy  Y  1  7  1  5  3e8  3ef  0  0
	asy  Y  1  7  1  9  2e8  2ef  0  0

Your input is very much appreciated!!!

P.S.
By the way, I tried one 524H with another brand of multi-io card.
After the first login prompt on tty0, I typed a few characters.
There were no echo's and the console was dead too. Does anyone
know about this??
