I can't get the sync to come up getting KPilot up on my ttys0.

-My computer has only one serial port so that should be ttys0.
-I created a symbolic link /dev/pilot to /dev/ttys0
-I did "chmod 666" on both ttys0 and pilot
-When I crank up KPilot it says something like "cannot open /dev/pilot"
-As root, when I do "ls -l /dev/ttys0 I get 

crw-rw-rw-    1 alandd   uucp       3,  48 Aug 30 13:30 ttys0

Does that mean some other process owns ttys0?  If so, how do I find out what 
it is?
