What parameters did you pass to stty?
% stty -F /dev/ttyS0 -a
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

I didn't mean so that you could use the kermit transfer protocol, but purely so you could use it's built in serial port config options. I used a similar setup to upload/download config and logging data at one point.
I may not be testing a lot more on this setup right now, though, as we haven't yet decided whether or not we are going to use it.
