3.5 Unidisk question

[bigbob@pb.seflin.org (Robert Stoecker)]

I just purchased a 3.5 Apple Unidisk on apple2.marketplace and it works 
fine.  I already have a 3.5 Unidisk, and this new one is 'just in case' 
the original breaks down.

Since I purchased both of these used, I have no manuals for them, but I 
pose the following question:   Since the Unidisk comes with a cable 
terminating in a RSC232 connector, what is the serial jack on the back of 
the drive used for?   It's pretty obvious I can't daisy-chain them 
together, and the Apple card (in slot 6) has only one lead.    Is there a 
connection that can be made to my hard drive by daisy-chaining it to the 
back with appropriate cables and terminators?

Any advice will be appreciated.
