Serial port pin control

I'm trying to control a relay via a com port, but i'm unable to use all of the pins. I open a com port and only "power lines" are given me some power, but i'd like to use all the pins. At the moment i have to use separate serial ports for each relay.
I could connect 2 relays on one com port via data pin, but like that one relay has to operate to get the second one to operate and i don't want that.

Any information is welcome.
