I don't see how that would apply to a word being included in my packet.
Well, from this statement, you probably need to drop back to basics. I would think that sending a string like 2r0807500, where 2 is the motor to control, r is to run it in reverse, 080 would be the speed 80 for it to run, and 7500 would be the delay of 7.5 sec., would be easier to work with. A string like this can easily be captured, the data parts captured into variables using string functions, and then the commands processed by "AFMotor", what ever that is. I think you would easier understand simple string operations than the 48 previous "array" post that have not produced working code.
