Not without a lot of programming, no. I looked into USB and decided against it. You have to weigh the cost of the component versus the cost of your time writing/debugging and the time it holds the project up. > Also, what is the advantage in the speed when using USB and not > RS-232 communication? is there a big different between this two > types? Like I said, our app never required huge amounts of data, and we already had written a fairly effective RS-232 component which I just tightened up a little (a 2 second timeout for realtime comms - no way!).
