RS-232 control of several relays

I want to use an RS-232 port to control several (at least 8, but preferably
16) relays individually. The load on the relays is low voltage/low current.
Basically, I want to use RS-232 to close the relay to replace a PC power
switch, so I can boot a machine on demand from another.
This is a school project, so I'm looking for a low-cost solution. I'd prefer
a trip to Radio Shack instead of a commercial solution. I did find this
component, which looks suitable: http://www.elabinc.com/ede300.htm
Any suggestions? Am I on the right track?
Thanks for the help!
Steven
