question: protected void encodeLinePrefix ( OutputStream outStream , int length ) throws IOException { outStream . write ( '*' ) ; crc . value = 0 ; tmp [ 0 ] = ( byte ) length ; tmp [ 1 ] = ( byte ) sequence ; sequence = ( sequence + 1 ) & 0xff ; encodeAtom ( outStream , tmp , 0 , 2 ) ; }
target:  Each UCE encoded line starts with a prefix of '*[XXX]', where the sequence number and the length are encoded in the first atom.
