Can't confirm because what we had instead was a task to implement a custom protocol over an RS-485 linear bus. The device in question was only available on appointment, so we only had a few shots at this. Eventually we went with adding a checksum and resending the whole "packet" (one byte) when it didn't match, because we couldn't get the damn thing to send stuff correctly 100% of the time.
