try this:

	cat /var/log/dmesg | grep tty

this will tell you if the kernel detected any serial ports.

The longer the system is up and running the kernel messages slip away
from the dmesg command, but the original boot messages are stored in 
/var/log/dmesg

If you get something back like

ttyS00 at 0x03f8 (irq = 4) is a 16550A

then /dev/ttyS0 should be working, If not, check your kernel
configuration and build a kernel with serial ports
