Hi Oliver, I've just checked the issue. The "normal" coreutils stty supports such baudrates, but not busybox one: http://lists.busybox.net/pipermail/busybox/2008-February/064253.html So for buildroot one will have to choose normal coreutils and not busybox ones :-( I also had problems with iptables version from busybox, but I haven't look at the code.
