Here's how to find out which rpm created your /dev/ttyS*
and what they were originally:

# rpm -qf /dev/ttyS0
dev-2.5.9-1
# rpm -qilv dev | grep ttyS
crw-r--r---     root     root     4,  64 May 05 16:32 /dev/ttyS0
crw-r--r---     root     root     4,  65 May 05 16:32 /dev/ttyS1
crw-r--r---     root     root     4,  66 May 05 16:32 /dev/ttyS2
crw-r--r---     root     root     4,  67 May 05 16:32 /dev/ttyS3

Here is how to see changes in your dev files:

Comparing to your installed rpm database:
# rpm -V dev
Or compairing to the rpm file on the RHL5.1 CD:
# rpm -Vp /z/RedHat/RPMS/dev-2.5.9-1.i386.rpm
