Skipping ttyS2??

[Jeroen Akershoek <jeroena@sara.nl>]

Hello,

I've got a system with one serial port on the motherboard and four other
ports on two PCI slots (2 each)
The kernel detects these as ttyS0 (onboard), ttyS14/S15 (1st PCI card)
and ttyS47/S48 (2nd PCI card).
We've got some pretty old proprietary software that insists on using
ttyS0-3, so I thought I'd just symlink
the higher ports.

I've made a rules file with the following:

KERNEL="ttyS14", SYMLINK="ttyS1"
KERNEL="ttyS15", SYMLINK="ttyS2"
KERNEL="ttyS47", SYMLINK="ttyS3"
KERNEL="ttyS48", SYMLINK="ttyS4"

This works fine with one exception: ttyS2 isn't symlinked

crw-rw----  1 root dialout 4, 64 Jun 14 10:07 /dev/ttyS0
lrwxrwxrwx  1 root root        6 Jun 14 12:15 /dev/ttyS1 -> ttyS14
crw-rw----  1 root dialout 4, 66 Jun 14 12:15 /dev/ttyS2
lrwxrwxrwx  1 root root        6 Jun 14 12:15 /dev/ttyS3 -> ttyS47
lrwxrwxrwx  1 root root        6 Jun 14 12:15 /dev/ttyS4 -> ttyS48

udevtest says that the rule matches and that it's creating the link.
Changing the order, changing the symlink, changing SYMLINK to NAME or
removing
the other rules have no effect either. It just seems that this device is
skipped or maybe
later overridden by the original 4,66 device (udevtest doesn't say
anything about it
though).

Anybody got ideas on this?

Regards,
  Jeroen
