Standart CRC16 or CRC32 algos with standart constants. This has ones point- byte sex.

Better way to know any algo is reverse app wich calc or check it.

@ssa: I suppose that you need it to send commands to Samsung. I have working on it too, but there is one more problem. FCS16 used to communiaction with Samsung 3G phones use custom hash table

Anyone can help .. ?
