SHELL "sudo ln -b /dev/ttyUSB0 /dev/ttyS0" WAIT

and it doesn't work.... plase someine Help ME!!! =)

sudo does not ask for the root password.

Good. Do you see any "Defaults targetpw" in the file?

This makes no sense, as you have to specify the granted command, i.e. /bin/ln, therein instead. But the first rule you mentioned should do already.
