![]() I would be extremely grateful if anyone who knew C would mind translating it for me? You don't even have to write the AutoIt Code for me, just explain in plain English what the steps of the algorithm are and I'll write it. The wikipedia page on it has code written in C that performs the checksum, but I don't know C and am having trouble trying to translate it. Note that the checksum values are still read in and parsed (so it is still an error if they are missing) but their values are not checked. However, I can't find a single place online that just goes through the steps of a Fletcher Checksum. Ignore Checksums The -ignore-checksums option may be used to disable checksum validation of input files, for those formats which have checksums at all. I know that I'll have no problem once I know the algorithm and can simply code it in AutoIt. If the message on the serial port is X&sabe4, then the Fletcher 16 algorithm is applied to the X.

We use this algorithm for generating checksum in order to get proof of whether the message was delivered precisely. ![]() Our engineers told me it is a "Fletcher's Checksum" and I have scoured the internet and these forums for any sort of help duplicating this checksum in AutoIt. The task of the Fletcher 16 algorithm is to transform any long input string to 16 bit namely 4 hexadecimal number. Everything is all good, except that the hardware that normally creates these strings also sends a 4 digit checksum at the beginning of each string. If the message on the serial port is X&sabe4, then the Fletcher 16 algorithm is applied to the X. At the moment, I've been assigned a task at my job to create a small program that will basically spam our proprietary strings over a TCP connection to a controlling software program.
