You need to have documentation of how to communicate with the device. You say you have used serial communication to communicate so any details of how to communicate depends on the device. I doubt that anyone here is familiar with the device. So if there is something more specific you need help with then you need to be more specific.

sorry.. i think ill rephrase it. My device im working on is a One Touch Ultra 2 device by lifescan inc. There is no driver to it because of budget problems i have not purchased its software driver. So i have used serial communication port codes to open the connection through USB to device but i need to communicate with the device(like as if i am creating a driver in the codes) with commands and retrieve data etc. if anyone can help i would much appreciate it
