It is only used by login for the syslog entries.  Logins via dialup
connections are marked in a special way.  It's really not critical whether
the guess is right or not.  But I would prefer it to be right.

Maybe the kernel could automatically symlink /dev/ttyS[?] to the physical
devices in a standardized manner.  Currently, with a little black magic in
mint.cnf it is even possible to associate "/dev/modem" with your keyboard.

Ciao
