This field is useless, nobody uses hardwired RS-232 terminals
anymore.

What we should do is add a systemcall or sysctl, so session creators
like getty, sshd and similar can install a session indentifying string
on the session, and then dump that in the accounting.

sshd would log IP+port and possibly also credential used for auth.
