Anything in your /etc called serial.conf
	try setting the value then reload the serial module
	
# These are the standard COM1 through COM4 devices
#
#/dev/ttyS0 uart 16450 port 0x3F8 irq 4
#/dev/ttyS1 uart 16450 port 0x2F8 irq 3
#/dev/ttyS2 uart 16450 port 0x3E8 irq 4
#/dev/ttyS3 uart 16450 port 0x2E8 irq 3

I'm using slackware, maybe there is something similar in /etc
	do a grep -r tty *   see it any files pop up
most systems only enabled COM1 and COM2. Just uncomment them if they are
there.
