HA! Found the problem --- thank-you everyone. Aparently, this little
device expects a 0x01 as the first byte of any command. Heh. Works
now.
So if you need dry contact I/O ... this seems to work for FreeBSD...

bytes = write(fd, s, strlen(s));
printf("wrote %d bytes %s\n", bytes, s);
sleep(1);
if(s == s1)
s = s2;
else
s = s1;
}
return 0;
}
