Hi all

I have in my hands a legasy serial protocol that clames to have as a means
of verification a CRC32 based on 104C11DB7h polyonym with initialization
value 0xFFFFFFFF.
From a capture i did on the packets i got the folowing bytestream where the
last four bytes are supposed to be the CRC32 of the first eleven (all values
in hex)

A3 00 0B 20 00 20 40 2D 00 43 20 E1 51 FE A7

Is it possible? I tried any algorithm i found on the internet and I can't
find any relation to the result of the algorithms and the value in the
captured bytestream.
