microcontroller - CRC16 checksum: HCS08 vs. Kermit vs. XMODEM - Stack Overflow

you can implement 16 bit IBM, CCITT, XModem, Kermit, and CCITT 1D0F using the same basic code base. see http://www.acooke.org/cute/16bitCRCAl0.html which uses code from http://www.barrgroup.com/Embedded-Systems/How-To/CRC-Calculation-C-Code
