The Macintosh DIN 8 connectors have only one handshake output line (HSKO)
that can either be used for line control (DTR) or flow control (RTS).

The 'rtscts' on NetBSD/mac68k is a lie in that there is no 'rts'
functionality, but 'dtr' flow control. Use 'dtrcts' in place of 'rtscts'
and make sure you use a cable wired for hardware handshake (RTS shorted
with DTR on the 25 pin connector, especially).

If you are interested in details, search the mailing list archives; this
has been rehashed a few times on the lists.
