4.1 Checksum algorithm

The checksum algorithm is that convert all the characters of the command string

(the first character to the characters before [CHK]) into ASCII hexadecimal values, and

take out the lowest 2 digit value after adding up, and then convert this value back to an

ASCII string, for example as below.

Example:

Command: Restart CAN converter module, RA[CHK]<CR>.

1. String sum = 'R' + 'A' = 52h + 41h = 93h.

2. Therefore, the checksum

is 93h, then [CHK] = ”93”.

3. The command string contains the checksum is "RA93<CR>".
