I see you have several previous questions on the same subject (for example Raw socket Connection.). If the method suggested here does not work, you're going to have to be more specific. Give us the details needed to help. What is this device you are trying to communicate with? Which operating system does it run? Which operating system does your computer (which you will use to communicate with this equipment) run? How do I post a question effectively? has more advice.
