Help in x10 Programming

[Simple]

Hi guys,

I'm new to this forum.
I'm having problems creating a simple program to send bytes to the serial port to the x10 protocol.
The protocol I'm using is CM12U, somewhat similar to CM11A.

I've read up about it on standard transmission and extended transmission and I'm currently using x10 Java API to work with.
My main concern now is sending a simple command to turn ON/OFF an appliance module (AM12U).

Can anyone guide me with my programming?   

I will provided the codes if necessary.
Any help, guide, suggestions or hints are greatly appreciated!

Regards,
Riz
