I suggest you download the Linux scripts from https://github.com/OneRNG/onerng.github.io/blob/master/sw/onerng_3.5.orig.tar.gz?raw=true and see if the commands in files/onerng.sh make any difference. A FreeBSD version of the stty command and then using the "echo" and "dd" commands to set up the device and pull data Not sure it will make a difference, but the best way to test it is by doing what is expected in Linux Regards, Gary
