Perhaps if you provide what device you are attempting to communicate with you may get more responses. The solution may be much simpler than attempting to understand the protocol as most use cases it is just sending the desired command through the RS232 interface and waiting for the response. Generally, using the port in binary (or byte mode) is the most reliable method. What have you tried so far? Do you have any Code written?
