On my Sparc Classic (NetBSD-current 1998/12/19) there seems to exist a 
   problem with the DCD signal.  Mgetty complains about an "tio_get_rs232_lines: 
   TIOCMGET failed: Inappropriate ioctl for device" every time when
   initializing the serial port.


i seem to recall that TIOCMGET support was lost when charles hannum
gave the zs driver a *major* overhaul, when i was looking at the
driver some time ago..


(i may be wrong.)
