No, not yet. What kind of handshake does your serial line use? Did you tried 
to disable s/w *and* h/w handshake ("stty clocal -crtscts -ixoff 
</dev/ttyS0") or even put the port into raw mode?

And how are you "outputting" your stuff to ttyS0? Is your controlling 
terminal on ttyS0 and you're doing a "cat bigfile" or are you doing something 
like "cat bigfile" >/dev/ttyS0"?

Salut, Jörg
