can anyone tell me how to do the parsing?

[Tarun Batra]

i have the information as shown below.
I have to parse the DATA PART that i will get from a machine and fill the values like Rinse mode,status of machine....
I will get data on Com Port,i have to do it in c++.
I have written the code to open the com port and send Data demand(command)


Data format
・ All data isASCII character code without checksumand CR.
・ Range ofMachineNumber start from0000 to 9999
・ If there is no top digit at data part, itwill be zero suppression and put space to fill it.
・ Calculate sum total from top till before checksum (１bite unit), then recognize this
complement of 1 as checksum.
・ Finish of format isCR Hexadecimal: OD

Data demand(command)
   CM”      “00”         Checksum       CR
(2 bite)   (2 bite)



Monitor data(response)
“RE”              “00”          MachineNumber    Data part
(2 bite)         (2 bite)         4bite            128 byte
