Serial device control through rs232 via my own web page

Hello!
I just created a web page using html and javascript. The page centered on an image of a control panel with various buttons. Next to each button there are 2 rectangles the squares when crushing the button pass from red to green (on off). My question is this: can you control a serial machine through my web page? (If I press on the button on the site it is turned off and also on the serial machine it goes from on to off?
thanks
