ps auwx | grep 621  (or 1438) :-)

They're just other processes running making use of the port. If things are 
more problematic and you can't trace it, "lsof /dev/ttyS0" or "fuser -v 
/dev/ttyS0" will reveal the process using the device (generally speaking, I 
prefer lsof - I sometimes have problems with fuser reporting back the right 
data)

Find out what they are, decide if you want it running, and if not:
	kill <pid>
eg,
	kill 621

That should do the job :)
