Note 1: Xor checking four higher and lower bits’ confirmation: Xor value and four higher and lower
bits are smaller than or equal to 9 will be added with 30h and turned to be ASCII code number for
sending, for example, four higher bits of Xor checking is 6, and this plus 36h is 6 in ASCII for sending
out; Xor, four higher bits and four lower bits which are larger than 9 will be added with 37h and turn to
