The "ttyflags" problem still occurs with 1.3_BETA.  It's persisted
through 1.3_ALPHA, too.  The description of the problem is that the
system will hang at the line "ttyflags -a" in a stock /etc/rc.  More
specifically, it hangs when it gets to tty00 in a stock /etc/ttys.  A
backtrace gives:

    _Debugger
    _nmihand
    _lev7intr
    _spec_open
    _vn_open
    _sys_open
    _syscall
    _trap0

and then the debugger hangs as well.  This happens whether or not there
is a device attached to the Mac's serial port.

My hardware is LCIII + 68882, 36MB RAM, external SCSI.  Everything works
fine with GENERIC-47.  The problem only occurs with GENERIC-48 and up.

I would love to help someone debug this problem and make the LCIII a
fully functional system again.
