tset: can't initialize terminal

["Crist J. Clark" <cjclark_(_at_)_reflexnet_(_dot_)_net>]

I am trying to figure out what I broke and how to go about fixing
it. When I login at the VGA console of an i386 OpenBSD machine, I get
the following,

  tset: can't initialize terminal type su (error -1)
  Terminal type? _

Where it prompts me for a terminal type. I believe this is coming from
the following code in .login,

  if ( ! $?TERMCAP ) then
          tset -Q  '-mdialup:?vt100' $TERM
  endif

I put a line,

  echo "TERM: " $TERM

In front of that and sure enough I got,

  TERM: su

Before the error message. My /etc/ttys seems pretty normal,

  ttyC0   "/usr/libexec/getty Pc"         vt220   on  secure
  ttyC1   "/usr/libexec/getty Pc"         vt220   on  secure
  ttyC2   "/usr/libexec/getty Pc"         vt220   on  secure
  ttyC3   "/usr/libexec/getty Pc"         vt220   on  secure
  ttyC4   "/usr/libexec/getty Pc"         vt220   off secure
  ttyC5   "/usr/libexec/getty Pc"         vt220   on  secure
  ttyC6   "/usr/libexec/getty Pc"         vt220   off secure
  ttyC7   "/usr/libexec/getty Pc"         vt220   off secure
  tty00   "/usr/libexec/getty std.9600"   vt220   on  secure
  tty01   "/usr/libexec/getty std.9600"   unknown off
  tty02   "/usr/libexec/getty std.9600"   unknown off

The only change I recall being to the first serial device. I should
note that error does not occur for network logins.

If anyone remembers the 'Read-Only /' thread I have been perpetuating,
this is the machine I was using. Any ideas what I have broken and how
to repair it? Thanks.
