Define Documentation

#define SB_SERUSB_MAX_REQUEST   256

SB_SERUSB_MAX_REQUEST is the maximum allowable string for a serialized command or response over the USB. The longest request will be for the multi-read command, and we may see fit to extend this size. The multi-read response may also be even longer, but we do not necessarily have to allocate buffer space for the entire response, since we can process it as it comes in.
