followed with two bytes of CRC check sum, which is the adding sum of the original character
string.
Take the DI+(CR) command as an example. Assume that DI+(CR) would return
110m3(CR)(LF)( the string in hexadecimal is 2BH, 31H, 32H, 3311, 34H, 35H, 3614,
371-1, 45H, 2BH, 30H, 6DH, 33H, 20H, ODEI, OAH) , then PDI(CR) would return
H 0m3!F7(CR)(LF). '!' acts as the starter of check sum which is yielded by adding up
the string 2BH, 31H, 32H, 3311, 34H, 3511, 36H, 3711, 45H, 2BH, 30H, 6DH, 3311, 2011.
