- I'm doing an SDLC implementation in software (processing every bit) and
- am stumped by the CRC calculation.
- I receive a packet 03h,05h,08h,17h,31h,94h, the last two bytes of which are
- the CRC. This is in MNP level 5. I've read several versions of how the
- SDLC CRC is computed, but I can't reproduce it. I've tried CRC-CCITT,
- CRC-16, LSB first and MSB first, initialising to 0s and 1s, but there's
- something missing.
-
- Suggestions, anyone ?
