here's the pinout on the 850 interface port 1:

pin 1  DTR
pin 2  carrier detect
pin 3 send data (out)
pin 4 receive data (in)
pin 5 ground
pin 6 DSR
pin 7 RTS
pin 8 CTS
pin 9 nc?

I usually use only pins 2, 3, and 5, and use Xon Xoff.

Did you know?  That when you buy something "made in China", something like
half the money you pay goes to the Chinese government.  The same government
that did Tiananmen Square last June.  Don't think I'd want to give them any
money, not after that.  Don't worry about putting workers over there out of
work, they get paid even if there's nothing to do.  Or so I've heard.
