Some things to check:

look at the output from dmesg or /var/log/kern.log and see what it
says about the serial ports.  It will probably talk about tty a bit.
Does it see your ports?

Try to cat from /dev/ttyS0, /dev/ttyS1, /dev/ttyS2, and /dev/ttyS3.
At least some of those will report an error -- ones that Linux doesn't 
detect.  If it does detect a port on the device you're trying, cat
will just appear to pause for a bit; use Ctrl-C.  This is a way to
check to see if Linux is seeing the port.

See what /proc/interrupts says.  Also, /proc/ioports can be
instructive.

Try using Minicom set to a port speed of 9600.  Does the modem respond 
to AT at that speed?  Is minicom set to the proper serial port?
