It definitely sounds like udev is not keeping track of the symlink.
Unfortunately I do not use a dialup modem anymore, when I still had
it installed - FC3 did keep track of the symlink properly. It was a
US Robotics hardware modem on a PCI card.
Is your udev up to current patch level? That's always the first thing
before filing a bug report - make sure your system is up to date -
there have been a lot of patches, and some to fix udev issues.
If the size of the update download is an issue with your dialup
connection, and if you have a DVD drive, I can mail you the updates
on DVD - maybe it will resolve your issue.
If your system isn't updated, you can try (from CLI as r00t)
yum update udev hal
That will just pull in udev and hal updates and their dependencies
and may be all that you need to resolve this issue.
Michael: I think you may have missed my early discussion of this
problem, namely: "I use it to dial in to an old mainframe." My internet
connection is via broadband so I do have all the latest patches
installed. I appreciate your offer, tho. From my reading so far, UDEV is
good, but still prone to some problems. I shall keep investigating, but
at least for now, I can live with using ttyS14 when I have to refer to
the modem -- there's still a chance that will stop working, I suppose,
since I didn't try a reboot after I made that discovery. I'll have to
wait till morning to see.
