Oh that's very disappointing.
I have tested that on a serial line, and it does work in my case ...

Could you provide me the "sb" command line you use (or rather your minicom or

And by private mail, I'd like the output of :
while true; do strace -T -tt -f -xx -s 4096 -o /tmp/forRobert.txt -p $(pidof sb); done

Cheers.
