  •         if (segmentsRequired > request.getMaxSegmentsAccepted() || segmentsRequired > 128)
                throw new BACnetException("Response too big to send to device; too many segments required:" + segmentsRequired + ", accepted: " + request.getMaxSegmentsAccepted());

    above the code to determine the amount of acceptable segment messages.

    the implementation for getMaxSegmentsAccepted is wrong. it is defined as a bitmap.
    so we should change that piece of code to:

        public int getMaxSegmentsAccepted() {
        	switch (maxSegmentsAccepted)
        	case 0:
        		return 64;
        	case 1:
        		return 2;
        	case 2:
        		return 4;
        	case 3:
        		return 8;
        	case 4:
        		return 16;
        	case 5:
        		return 32;
        	case 6:
        		return 64;
        	case 7:
        		return 128;
        	// 3 bits - we can't get here
            return 64;

    this is in the class ConfirmedRequest.
