just an idea:
is ttyS0 really the name of the interface ?
do you see "ttyS0" in the output of ifconfig ?
I do not know the way your ipaq is conntected, but i would guess the
name of the interface is "ppp0" or "usb0".
you cold try ip adress instead of the name of the interface, e.g.
iptables -A INPUT -i 192.168.0.200 -j ACCEPT
iptables -A OUTPUT -o 192.168.0.200 -j ACCEPT

but if you are running iptables already, finding the error is not easy.
maybe you post your full iptables script ?

good luck
