It's like this: /dev/modem is, at least on RedHat, a symlink to
whatever your modem is connected to.  Since modems don't move much,
pointing stuff to /dev/modem can cause problems when you don't have
_everything_ pointed there, since two different names point to the same
port -- which can cause locking problems.

Now, if you _do_ have a situation where your modem chanegs ports
regularly, I'm beginning to think (as someone who has this problem)
that maybe the work involved in making sure _everything_ points to the
symlink is worth not having to track down _everything_ _everytime_ I
move a modem.  But that's a personal opinion.

In any case, don't use the cua devices, if you're on a 2.0 or better
kernel; they're deprecated and they're going away.
