I disagree.

6 should go to both pin 6 and 8.

If you don't wire DCD somehow, you enter a world of OS specific
trick to enable CLOCAL handling. Not all serial port driver have
cua devices. Not all applications can open in non-blocking mode
to enable clocal. 

If you do your adaptors right the first time, you'll simplify your
life later.
