Yes, you can.

At first read the documentation of the hardware. This will (hopefully) tell you baud rate, etc. and the syntax and commands.

Afterwards write a program, that chooses the right serial port and communicates with the device.

to communicate with the device will be no problem. That where is the problem is what have I to send to say for example (plug on the firste led)? The documentation of the hardware will be always avalaible? – anubis Jun 20 '15 at 18:41
The rs232 protocol is absolutly vendor specific. We cannot tell you what to send for switching on the first LED, unless you provide a documentation of the vendor. Not every vendor publishes documentation. – slartidan Jun 20 '15 at 22:25
