Packing the serial port data according to the packing time andpacking length under the transparent transmission mode .The frame mechanism of serial port is based on the packaging time and the packaging length. The case are asfellow.1. Packing time set as 10ms and the length as 512.If the internal time for serial received the data more than 10ms, or the length more than 512, K7 send packing tonet when the serial port receive data.2. If the packing time is 0 and the packing length is not 0, only the packing length work; and if the packing length is0 and he packing time is not 0, only the packing time work.3. Set the packing time is 0 ms and the packing length is 0
