1. port control, cd tray control

How could i control a serial port, eg turn on pin 2 on com2? i have an
unused serial cable and i would like to use it to control some simple
robotics, how could i say, power a small light, or just use it as a switch
with an external power source. thanx.
Also, how can i control the cd tray ie open/close and find out the state of
the tray (open/closed)
