That's documented in the fnctl docu (at least the 2.1 version I read).

You pass a string containing the byte array you want to input. The module then copies the string to a new memory array, and passes this array's address. The modified memory array then is converted back to a string which is returned by the fnctl as function result.

You could convert your integers by hand, or use the struct module to do this.
